To diagnose premature ventricular contractions (PVCs), a health care provider will typically listen to your heart with a stethoscope. You may be asked questions about your lifestyle habits and medical history.

Tests are done to confirm a diagnosis of premature ventricular contractions.


An electrocardiogram (ECG or EKG) can detect the extra beats and identify the pattern and source.

An electrocardiogram (ECG) is a quick and painless test to record the heart's electrical activity. Sticky patches (electrodes) are placed on the chest and sometimes the arms and legs. Wires connect the electrodes to a computer, which displays the test results. An can show if the heart is beating too fast, too slow or not at all.

If you don't have premature ventricular contractions (PVCs) very often, a standard may not detect them. Your health care provider may ask you to use a portable device at home to obtain more information about your heartbeats. Portable devices include:

  • Holter monitor. This portable device can be worn for a day or more to record the heart's activity during daily activities. Some personal devices, such as smartwatches, offer portable monitoring. Ask your health care provider if this is an option for you.
  • Event monitor. This portable device is intended to be worn for up to 30 days or until you have an irregular heart rhythm (arrhythmia) or symptoms. You usually press a button when symptoms occur. But some monitors automatically sense the irregular heartbeats and then start recording.

Your health care provider may also recommend an exercise stress test. This test often involves walking on a treadmill or riding a stationary bike while an is done. An exercise stress test can help determine whether exercise triggers your PVCs.


Most people with premature ventricular contractions (PVCs) who don't have heart disease won't need treatment. If you have heart disease, PVCs can lead to more-serious heart rhythm problems (arrhythmias). Treatment depends on the underlying cause.

A health care provider may recommend the following treatment for frequent PVCs:

  • Lifestyle changes. Eliminating common premature ventricular contraction (PVC) triggers — such as caffeine or tobacco — may reduce the number of extra beats and lessen symptoms.
  • Medications. Blood pressure medications may be prescribed to reduce the premature contractions. Those used for PVCs may include beta blockers and calcium channel blockers. Drugs to control the heart rhythm also may be prescribed if you have a type of irregular heartbeat called ventricular tachycardia or frequent PVCs that interfere with heart function.
  • Radiofrequency catheter ablation. If lifestyle changes and medications don't help reduce the PVCs, a catheter procedure may be done to stop the extra beats. In this procedure, a health care provider threads one or more thin, flexible tubes (catheters) through an artery, usually in the groin, and guides them to the heart. Sensors (electrodes) on the tip of the catheter use heat (radiofrequency) energy to create tiny scars in the heart to block irregular electrical signals and restore the heart rhythm.

Clinical trials

Self care

The following self-care strategies can help control premature ventricular contractions (PVCs) and improve heart health:

  • Track your triggers. If you have frequent PVCs, keeping a diary of the day and timing of symptoms may be helpful. A diary may help identify foods, drinks or activities that trigger the premature ventricular contractions.
  • Modify your substance use. Caffeine, alcohol, tobacco and stimulant drugs are known triggers of premature ventricular contractions. Reducing or avoiding such items may reduce PVC symptoms.
  • Manage stress. Anxiety can trigger irregular heartbeats. Find ways to help reduce emotional stress. Getting more exercise, practicing mindfulness and connecting with others in support groups are some ways to tame stress. If you need help managing anxiety, talk to your health care provider about strategies and medications that may help.

Preparing for your appointment

You're likely to start by seeing your family care provider. You may be referred to a doctor trained in heart diseases (cardiologist).

Here's some information to help you get ready for your appointment.

What you can do

Make a list of:

  • Your symptoms, how they feel and when they began
  • Key medical information, including other recent health conditions and family history of heart disease
  • All medications, vitamins and other supplements you take and their dosages
  • Questions to ask your health care provider

Take a friend or relative with you, if possible, to help you remember the information you receive.

For premature ventricular contractions, questions to ask your health care provider include:

  • What is likely causing my symptoms?
  • What tests do I need?
  • What treatment approach do you recommend, if any?
  • What lifestyle changes can I make to reduce my symptoms?
  • Do I need to eliminate alcohol and caffeine?
  • Am I at risk of long-term complications?
  • How will you monitor my health over time?
  • Do I need to adjust the medications I'm taking for other health conditions?

Don't hesitate to ask other questions.

What to expect from your doctor

Your health care provider is likely to ask you questions, including:

  • Do your symptoms come and go? If so, when are they likely to occur?
  • Do you drink alcohol? If so, how much?
  • Do you use caffeine? If so, how much?
  • Do you smoke or use other nicotine products?
  • Do you use illegal drugs?
  • How often do you feel stressed or anxious? What do you do to manage these feelings?
