Can COVID Cause Heart Palpitations?

What “Heart Palpitations” Actually Means (And Why It Feels So Dramatic)

“Heart palpitations” is a catch-all phrase for the sensation that your heart is doing something noticeableracing, fluttering, pounding, skipping, or thumping. It can feel like your chest is hosting a tiny drum solo, and your brain did not buy tickets for this concert.

Important detail: palpitations are a symptom, not a diagnosis. Sometimes they’re caused by a harmless extra beat. Sometimes they’re caused by a rhythm problem (an arrhythmia). And sometimes they’re caused by everything around your heartfever, dehydration, stress, poor sleep, medications, or a post-viral nervous system that’s temporarily confused.

So… Can COVID Cause Heart Palpitations?

Yes. COVID-19 can be associated with palpitations in two main windows:

• During acute infection: when your body is fighting the virus.
• After infection (post-COVID or “Long COVID”): when symptoms linger or show up weeks later. Public health and clinical resources list fast-beating or pounding heart/palpitations among commonly reported post-COVID symptoms.

Why COVID can affect your heartbeat

COVID isn’t just a “nose and throat” illness. It can stress multiple systems that influence heart rate and rhythm, including inflammation, oxygen levels, blood volume (hydration), and the autonomic nervous system (the body’s automatic “idle speed” controller).

Common COVID-Related Reasons You Might Feel Palpitations

1) Fever and inflammation: your body’s “high alert” mode

When you have a fever, your heart rate often rises. That’s normal physiology: your body is trying to circulate heat and immune signals. Add inflammation and stress hormones, and you may feel a racing or pounding heartbeat.

2) Dehydration (or not eating much) during illness

Fever, sweating, diarrhea, low appetite, and “everything tastes like cardboard” can lead to low fluid intake. When blood volume dips, your heart can beat faster to keep blood pressure stablehello, palpitations.

3) Low oxygen, coughing fits, and the “breathing tax”

Breathing difficulty increases the body’s workload. Even mild drops in oxygen or prolonged coughing can trigger a faster heart rate and a strong “thump” sensation.

4) Medication and stimulant effects

Some common illness helpers can also make your heart more noticeable:

• Decongestants (especially stimulant-type ingredients)
• Asthma inhalers or breathing treatments that can raise heart rate
• Caffeine/energy drinks (often used to “power through” fatigueunderstandable, but not always kind to your pulse)

5) Anxiety and “body scanning” (a very real feedback loop)

COVID can be scary. Even when symptoms are mild, uncertainty can crank up adrenaline. Adrenaline increases heart rate and makes normal heart sensations feel louder. Then you notice it more, worry more, andbamthe loop tightens. (It’s not “all in your head.” It’s your nervous system doing what nervous systems do.)

Palpitations After COVID: Long COVID and the Autonomic Nervous System

Many people report heart-related symptoms after the acute infection resolvesespecially a fast heart rate, pounding heartbeat, or feeling wiped out after small activity. Major medical resources describe fast or irregular heartbeat as a symptom that can occur with Long COVID.

Autonomic dysfunction: when your “automatic settings” get glitchy

Your autonomic nervous system controls heart rate, blood pressure, sweating, and digestionbasically the background settings you never think about until they’re annoying. Post-viral autonomic dysfunction is a recognized phenomenon, and scientific statements and clinical summaries describe autonomic issues and arrhythmia-related symptoms in some people after COVID.

POTS (Postural Orthostatic Tachycardia Syndrome): the “standing up makes my heart sprint” pattern

One specific form of autonomic dysfunction is POTS. In POTS, heart rate increases significantly when moving from lying down to standing, often along with dizziness, fatigue, brain fog, and palpitations. U.S. specialty centers have reported a connection between COVID and POTS-like symptoms in some patients, even after mild infections.

A classic clue: you’re okay lying down, then you stand up and your watch shows your heart rate shoots upand you feel shaky, lightheaded, or “wired but tired.”

When Palpitations Might Signal Something More Serious

Most palpitations are benign. But COVID (like other viral illnesses) can be linked to conditions that deserve medical evaluation.

1) Arrhythmias (true rhythm disorders)

An arrhythmia is a problem with the heart’s electrical timing. Some arrhythmias are mild. Others can raise risks and require treatmentespecially if accompanied by fainting, chest pain, or shortness of breath.

Clinical cardiology summaries note that certain arrhythmias (including atrial fibrillation) can occur during COVID illnessmore often in sicker or hospitalized patientsand may require long-term follow-up if newly diagnosed.

2) Myocarditis (inflammation of the heart muscle) or pericarditis (inflammation of the heart lining)

Viral infections can trigger myocarditis. Symptoms can include chest pain, shortness of breath, fatigue, and rapid or irregular heartbeats. If you develop new chest pain, fainting, or severe breathing symptomsespecially after a recent viral illnessseek urgent evaluation.

3) Blood clots and cardiovascular strain (less common, higher-stakes)

COVID is associated with increased clotting risk in some situations and can stress the cardiovascular system. Palpitations alone don’t equal a clot, but palpitations plus sudden shortness of breath, chest pain, or fainting should be treated as “get checked now” symptoms.

Red Flags: When to Seek Urgent Care (Not Just a Calm Google Spiral)

Get emergency care immediately if palpitations come with:

• Chest pain or pressure
• Fainting or near-fainting
• Severe shortness of breath
• Severe dizziness
• New weakness on one side, trouble speaking, or other stroke-like symptoms

If palpitations are frequent, worsening, or disrupting sleepeven without dramatic red flagsit’s still worth talking to a clinician for proper evaluation.

How Doctors Evaluate Post-COVID Palpitations

Clinicians typically start by figuring out what your heart is actually doing during the episodes and what might be triggering them. Expect questions like: “When does it happen?” “How long?” “What were you doing?” “Any dizziness, chest pain, or shortness of breath?”

Common tests (depending on your symptoms and risk factors)

• Electrocardiogram (ECG/EKG): a quick snapshot of your rhythm.
• Ambulatory monitoring (Holter or event monitor): records rhythm over 24 hours to a few weeks to catch intermittent palpitations.
• Blood tests: may check anemia, electrolytes, thyroid function, inflammation markers, and other contributors.
• Echocardiogram: ultrasound to assess structure and pumping function if indicated.
• Orthostatic vitals or tilt-table testing: if POTS or orthostatic intolerance is suspected.

What about smartwatches?

Wearables can be helpful for documenting heart rate trends and, in some models, capturing a rhythm strip. They’re not a full medical workup, but they can provide useful breadcrumbsespecially if you export readings and bring them to an appointment.

What You Can Do at Home (Safely) While You Wait for Answers

If you’re not experiencing emergency symptoms, these strategies can reduce palpitations and support recovery.

1) Hydrate like it’s your part-time job

Drink fluids regularly. If you’ve been sweating, having diarrhea, or eating less, consider oral rehydration solutions or electrolyte drinks in moderation. If you have kidney disease, heart failure, or are on fluid restrictions, ask your clinician what’s safe for you.

2) Go easy on stimulants (yes, including “just one more coffee”)

Caffeine, nicotine, and energy drinks can amplify palpitations. Try a short “stimulant vacation” and see if symptoms quiet down.

3) Eat steady, simple meals

Low blood sugar can make your heart feel jumpy. Aim for small, balanced mealsprotein + complex carbs + a little fatespecially if you’re recovering and appetite is unpredictable.

4) Sleep and stress: not glamorous, but wildly effective

Poor sleep makes palpitations more likely and makes you notice them more. Create a “boring bedtime routine” (dim lights, no doomscrolling, cool room). If anxiety is fueling symptoms, breathing exercises, gentle stretching, and guided relaxation can help.

5) Return to activity gradually (especially if you suspect Long COVID)

Some people experience post-exertional symptom worseningfeeling okay during activity but crashing afterward. If that’s you, pace yourself: shorter bouts, lower intensity, more rest breaks. Consider a clinician-guided return-to-exercise plan or cardiac rehab if recommended.

6) Track patterns like a detective (but not like a panicked detective)

Keep a simple log for 1–2 weeks:

• Time of episode
• Heart rate (if you have it)
• What you were doing (standing, showering, walking, lying down)
• Food, caffeine, and medications
• Symptoms (dizzy, short of breath, chest discomfort)

This turns “something weird happened” into actionable clinical data.

Medical Treatments: What Might Be Recommended

Treatment depends on the cause. There isn’t one magic “palpitations pill,” but there are many effective approaches.

If palpitations are from benign extra beats or sinus tachycardia

• Hydration and electrolyte management
• Reducing stimulants and alcohol
• Addressing sleep, stress, anemia, thyroid issues, or medication side effects

If POTS or autonomic dysfunction is suspected

• Increased fluids and salt intake (when appropriate)
• Compression garments
• Recumbent exercise (like rowing or biking) before upright cardio
• Medications (sometimes), guided by a clinician

NIH has also launched trials to evaluate treatments for autonomic symptoms in Long COVID, underscoring how common and impactful these issues can be.

If an arrhythmia is diagnosed

Treatment may include medications, addressing triggers, anddepending on the rhythmprocedures or anticoagulation. The plan is individualized based on the rhythm type and your health profile.

If myocarditis or pericarditis is suspected

Doctors may recommend rest from intense exercise, medications to reduce inflammation, and close monitoring. The key is prompt evaluation to protect heart function and guide safe recovery.

FAQ: The Questions People Ask (Usually at 2:07 a.m.)

How long do palpitations last after COVID?

It varies. Some people notice palpitations only during the acute illness. Others have episodes for weeks or months, especially if Long COVID symptoms develop. Persistent or worsening symptoms warrant evaluation so you can rule out treatable causes (like anemia, thyroid issues, dehydration, or an arrhythmia).

Can mild COVID cause palpitations?

Yes. Even mild infections can trigger dehydration, stress responses, or autonomic symptoms. Mild doesn’t always mean “your body didn’t care.” It may simply mean you weren’t hospitalized.

Should I exercise if I have palpitations after COVID?

Exercise can helpbut timing and intensity matter. If you have chest pain, fainting, severe shortness of breath, or suspected myocarditis, do not “push through.” For many others, a gradual, paced return is best. If your symptoms worsen after exertion, consider medical guidance before increasing activity.

Are palpitations always an arrhythmia?

No. Palpitations can occur with normal rhythm (just more noticeable) or with benign extra beats. But because COVID can be associated with arrhythmias in some cases, repeated episodes deserve a proper checkespecially if you have risk factors or red-flag symptoms.

Conclusion: Listen to Your HeartBut Don’t Let It Boss You Around

COVID-19 can cause heart palpitations during illness and in recovery. Often, the cause is non-dangerous (fever, dehydration, stress, stimulant effects), and symptoms fade as your body recalibrates. But palpitations can also be tied to Long COVID patterns such as autonomic dysfunction/POTS, or less commonly, to arrhythmias or inflammatory heart conditions like myocarditis.

The best approach is balanced: take palpitations seriously (track them, address triggers, seek evaluation when needed) without assuming the worst. Your goal is to translate a scary sensation into useful informationthen let your healthcare team help you choose the next right step.

Experiences Related to “Can COVID Cause Heart Palpitations?” (Realistic, Common Scenarios)

Below are composite experiences based on commonly reported patterns clinicians and major health systems describenot personal anecdotes. Think of these as “you’re not the only one” snapshots that may help you recognize what’s going on and what questions to ask.

Experience 1: “My heart started sprinting… while I was folding laundry.”

A lot of people describe palpitations as the moment their body’s normal “idle speed” vanished. They weren’t running. They weren’t even late. They were doing something deeply non-athleticlike folding towelsand suddenly their heart felt like it was chasing a bus. In many of these cases, the trigger turns out to be a recovery combo: mild dehydration (because water tasted weird for a week), poor sleep, and a little extra caffeine to compensate for fatigue. Once they start sipping fluids consistently, cutting back on stimulants for a few days, and getting more sleep, the episodes often become less frequent and less intense.

Experience 2: “It’s worse when I stand up, shower, or walk upstairs.”

This is a common post-COVID storyline: lying down feels okay, but standing up flips a switch. People notice their pulse jumps, they feel lightheaded, and their smartwatch basically starts narrating a suspense novel: “Heart rate: 132… while brushing teeth.” That pattern is one reason clinicians consider orthostatic intolerance or POTS-like symptoms after COVID. Folks often say the shower is the biggest villainheat plus standing still is a classic setup. Practical tweaks (cooler showers, sitting while drying off, compression socks, hydration, and gradually rebuilding conditioning with recumbent exercise) can make daily life feel more normal again.

Experience 3: “The palpitations made me anxious… and then the anxiety made the palpitations worse.”

It’s incredibly common for palpitations to trigger fear. Your heart is not a subtle organ. It’s basically a drummer with no volume knob. People describe checking their pulse repeatedly, scanning for symptoms, and spiraling into “What if?” modeespecially at night when everything is quiet and your thoughts have free Wi-Fi. Many find that learning the red-flag symptoms (chest pain, fainting, severe shortness of breath) helps reduce panic. Others benefit from a simple routine: slow breathing, a sip of water, writing down what they feel, and reminding themselves, “I’m monitoring thisand I’m getting it checked.”

Experience 4: “My tests were normal, but I still felt awful.”

This can be frustrating: an ECG looks okay, basic labs are fine, and yet the person still feels palpitations, fatigue, and exercise intolerance. For some, the next step is longer monitoring (like a Holter or event monitor) to catch intermittent rhythms. For others, the workup shifts toward autonomic function, sleep quality, iron levels, thyroid function, and recovery pacing. Hearing “normal tests” doesn’t mean “nothing is happening.” It can mean “nothing dangerous showed up today,” which is still good newsand a starting point for symptom-focused care.

Experience 5: “It faded slowlylike a dimmer switch, not a light switch.”

Many people expect recovery to be a straight line. Post-COVID symptoms often behave more like a toddler learning to walk: two steps forward, one step back, occasional dramatic flop. People commonly report that palpitations improve gradually when they protect basics (hydration, sleep, pacing, nutrition) and avoid big trigger spikes (intense workouts too soon, stimulant overload, skipping meals). The improvement can be slow, but tracking patterns often reveals progress: fewer episodes per week, lower peak heart rate, faster recovery after standing, and better tolerance for daily activity.

If any of these experiences sound familiar, the most helpful next move is simple: document what you feel, notice triggers, and bring that information to a clinicianespecially if symptoms are new, frequent, worsening, or accompanied by red flags.
