Heart Palpitations

Back To Heart

Heart palpitations are sensations that your heart is racing, fluttering, pounding or skipping beats. They are common and often harmless but they can sometimes be a sign of an underlying heart rhythm disorder or another health condition. 

At Banner Health, our heart specialists can help identify what’s causing your symptoms and whether treatment is needed. 

What are heart palpitations?

Heart palpitations are the feeling that your heart is beating differently than normal. You may become unusually aware of your heartbeat, even when you're resting.

Palpitations are a symptom, not a diagnosis. They can happen during exercise, while you're sitting quietly or even when you're trying to fall asleep.

In many cases, palpitations occur even when the heart rhythm is normal. In other cases, they may be caused by an arrhythmia, which is an abnormal heart rhythm.

Most heart palpitations are not serious, but recurring symptoms should be evaluated by a healthcare provider.

What do heart palpitations feel like?

Everyone experiences palpitations differently. You might notice these sensations in your chest, throat or neck.

  • Racing heartbeat: Your heart feels like it’s beating faster than normal, even when you aren’t physically active.
  • Fluttering or quivering: You may feel a fluttering sensation, butterflies in your chest or a flip-flopping feeling.
  • Skipped or extra beats: You may notice a stronger feeling heartbeat followed by a brief pause. These sensations are often caused by premature ventricular contractions (PVCs) or premature atrial contractions (PACs).
  • Pounding heartbeat: Your heartbeat may feel unusually strong or forceful in your chest,  throat, neck or ears.

How are heart palpitations diagnosed?

Your health care provider will help you find the cause of your symptoms. They will use several testing and diagnosis tools to check your heart health.

  • Medical history and physical exam: Your provider will review your symptoms, possible triggers, medications and family history. They will also listen to your heart and lungs.
  • Electrocardiogram (EKG): An EKG records your heart's electrical activity and can identify abnormal heart rhythms.
  • Holter monitor or event monitor: These are portable devices you wear for one day or more. They track your heart's electrical activity during your normal daily life.
  • Echocardiogram: This is an ultrasound of the heart. Doctors use it to look at your heart structure and valves.
  • Blood tests: Bloodwork can check for thyroid issues, anemia or electrolyte imbalances that may contribute to palpitations.

Treatment for heart palpitations

Your treatment plan depends on what is causing the palpitations. Some people do not need medical treatment, while others may benefit from medication or specialized procedures.

Lifestyle changes

You may be able to stop palpitations by:

  • Staying hydrated
  • Getting enough sleep
  • Reducing caffeine 
  • Managing stress
  • Limiting alcohol
  • Avoiding nicotine products

Medication

If a heart rhythm disorder is causing your symptoms, your doctor may prescribe medicine to control your heart rate or rhythm.

Procedures

Some arrhythmias can be treated with catheter ablation, a minimally invasive procedure that blocks abnormal electrical signals in the heart.

Monitoring

Your provider may recommend ongoing monitoring to track your symptoms and ensure your treatment plan is working effectively.

How to prevent future palpitations

Healthy habits can reduce how often you experience palpitations. 

  • Drink plenty of water so you stay hydrated
  • Limit or avoid alcohol
  • Limit stimulants like caffeine and nicotine
