Should I See a Doctor? When to Worry About Heart Palpitations

Believing that something could be wrong with your heart is a scary feeling. Heart palpitations  can make you fear the worst, but palpitations are actually quite common and usually nothing to worry about.

However, that’s not to say that you should ignore them completely. Rarely, they could be a sign of a more serious condition like AFib. Knowing when to worry about heart palpitations can help you catch certain conditions early so that you can seek treatment.

When to Worry About Heart Palpitations

Heart Palpitations occur for many reasons. You should contact your doctor if you experience heart palpitations frequently, for longer than a few seconds, or if they are accompanied with dizziness, loss of consciousness, chest or upper body pain, nausea, excessive or unusual sweating, and shortness of breath.

What are Heart Palpitations?

Have you ever felt your heart skip a beat or flutter in your chest? If so, you’ve experienced heart palpitations. A broad medical term, the term “palpitation” can mean many different things, including:

  • Feeling like your heart is beating too quickly
  • Feeling your heart thump in your chest
  • A heartbeat that feels irregular/out of rhythm/skips a beat

Any sensation that makes you aware of your heart beating is a type of palpitation. You can even feel these sensations in your throat or neck.

Common Triggers

If you’re worried that your heart palpitations are the result of a heart problem, here’s some good news – most palpitations are not caused by heart-related issues. Instead, they are commonly triggered by:

  • Exercise
  • Stress/Anxiety
  • Alcohol
  • Stimulants (caffeine)
  • Nicotine withdrawal
  • Hormonal changes during pregnancy
  • Low blood sugar

How to Reduce Heart Palpitations at Home

For the most part, palpitations caused by non-heart related triggers can be treated with simple home remedies.

For example, if you only feel your heart race when you’re anxious or stressed, relaxation techniques like meditation and deep breathing could be the key to reducing these palpitations.

Likewise, a thumping heart caused by stimulant use can be calmed by reducing your intake of tobacco products and caffeine. If you’re taking any medication, tell your doctor about the palpitations you’re experiencing to find out if your medication could be causing them.

Hydration and diet play a big role, too. Being dehydrated or having low levels of potassium can also trigger heart palpitations. If you have low blood sugar, eating too many carbohydrate-rich foods and processed sugars can increase your likelihood of experiencing palpitations.

When to See a Doctor

Nearly everyone will experience heart palpitations at some point. A majority of the time, they’ll be completely benign (not harmful). Other times, it could be your heart trying to tell you that something’s wrong.

You should call your doctor if your heart palpitations last longer than a few seconds at a time or occur frequently.

If you’re healthy, you don’t need to worry about brief heart palpitations that only happen every now and then. That being said, it’s still a good idea to monitor your palpitations and keep track of how often they happen and how long they last. They when, when you do visit your doctor, it will be easier for them to make an accurate diagnosis.

When to Call an Ambulance

If a person’s heart palpitations are accompanied by:

  • Loss of consciousness
  • Chest pain
  • Upper body pain
  • Dizziness
  • Shortness of breath
  • Unusual sweating
  • Nausea

These are possible warning signs of a heart attack or other serious heart condition that requires immediate medical attention. Call 911 or your local emergency number – it’s always better to be safe than sorry.

Serious Causes of Heart Palpitations

Sometimes, heart palpitations are a sign of a serious type of arrhythmia (irregular heartbeat) such as AFib or ventricular tachycardia (VT), or even heart failure.


Atrial fibrillation, or AFib, is a common condition that causes the upper chambers of the heart (the atria) to quiver irregularly instead of beating at a regular pace. This makes it difficult for the heart to pump blood to your lower chambers (ventricles) and out to the rest of your body. As your blood flow slows down, your risk of forming dangerous clots increases.

Untreated, AFib can increase a person’s risk of stroke 5-fold, so being able to recognize the early warning signs is important. However, because the disorder affects people in so many different ways, it is notoriously difficult to diagnose.

Common risk factors include:

  • Age (adults 65+ are most at risk)
  • High blood pressure
  • A family history of AFib
  • Hyperthyroidism (overactive thyroid)
  • A history of heart disease or previous heart surgery

You should ask your doctor about testing for AFib if you:

  • Have a high risk of AFib based on the factors above
  • Experience fluttering heart palpitations that last longer than a minute at a time
  • Have palpitations accompanied by dizziness/fainting/shortness of breath

Detected early, AFib can be treated with medication, ablation surgery, or a pacemaker.

Ventricular Tachycardia

Ventricular tachycardia, or VT, is a rare but serious type of arrhythmia that causes the heart’s lower chambers (ventricles) to beat too quickly. Like AFib, VT can result in dizziness and shortness of breath.
Heart Failure

If the heart is unable to pump blood effectively, heart failure can occur. Heart palpitations on their own are not a sign of heart failure – instead, they are just one of many symptoms that can occur. Some patients experiencing heart failure may not even experience palpitations at all.

According to the American Heart Association, some of the most common symptoms include:

  • Fatigue
  • Fluid build-up in the lungs
  • Rapid heartbeat
  • Loss of appetite
  • Shortness of breath
  • Confusion

However, keep in mind that heart failure symptoms vary from person to person, and women often experience different symptoms than men.

Don’t Panic (But Don’t Ignore the Signs, Either)

At the end of the day, most heart palpitations are as harmless as hiccups. If you are otherwise healthy and only experience them from time to time, you have no reason to panic.

However, while heart palpitations are usually not dangerous, it’s still in your best interest to get your symptoms checked by a cardiologist if the problem persists. And if your palpitations are accompanied by other symptoms, such as dizziness or weakness, it could be a sign of a more serious condition that shouldn’t be ignored.
