A palpitation — a skipped, extra or irregular heartbeat — is a type of abnormal heart rhythm, or arrhythmia. It occurs when an electrical signal fires from the wrong place at the wrong
time, causing the heart to beat out of rhythm. Many people are unaware of minor irregular heartbeats, and even completely healthy people have extra or skipped heartbeats once in a while. Palpitations are more common as you age. Usually, these occasional arrhythmias are nothing to worry about. But in some cases, extra or irregular beats can cause bothersome symptoms or lead to other types of sustained, rapid heart rhythms. Occasional, harmless
palpitations can have many causes: However, some palpitations may be symptoms of a more serious condition, such as: Many people experience palpitations (the feeling that their heart is momentarily racing or pounding), a skipped or extra beat or a fluttering or forceful beat. When you feel a "skipped" beat, what you are probably experiencing is an early
heartbeat. Because the heart contracts before the ventricles have had time to fill with blood, there is little or no blood pushed out to the body. Therefore you don't feel that contraction as a beat. The next beat will feel more forceful, as an extra volume of blood is then pushed out. However, some symptoms are more serious. Consult with your doctor if you experience any of these:

Published Feb. 9, 2018 , Updated Feb. 9, 2018 Pay attention to your heartbeatPeople say, “My heart skipped a beat,” when they’re scared or excited. But an irregular heartbeat is actually much more common than you’d think. “An irregular heartbeat is called an arrhythmia,” says Dr. Pugazhendhi Vijayaraman, cardiac electrophysiologist and director of cardiac electrophysiology at Geisinger Northeast. “There are many different types, which can be temporary or permanent. Often, arrhythmias are harmless; however, if you feel a persistent irregular heartbeat, see a doctor.” One type of arrhythmia, a premature ventricular contraction, or PVC, is the most common type of irregular heartbeat. A PVC happens when the heart beats too early, which causes a stronger second beat. This causes a fluttering or pounding sensation in the chest. Most people have at least one PVC every day, and many don’t even notice it. Things like caffeine, alcohol and stress can cause small, temporary arrhythmias like PVCs. But there are factors that can cause permanent arrhythmias, too. Here are four potential causes of a persistent, irregular heartbeat:
When to see a doctorWhile PVCs are normally harmless, certain types of arrhythmias, like atrial fibrillation and ventricular fibrillation (VFib), can lead to cardiac arrest and heart attack. VFib can paralyze the heart—making it unable to pump blood. If left untreated, VFib can lead to cardiac arrest. If you feel a persistent irregular heartbeat, your doctor can help diagnose the type of arrhythmia and monitor your heart. They may refer you to an Electrophysiology (EP) lab, where they can test, diagnose and treat arrhythmias. Get emergency medical attention if you experience dizziness, fainting, shortness of breath and pain in your chest. These symptoms could be a sign of a severe arrhythmia and heart attack. Similarly, if you notice numbness on one side of your body, confusion, facial drooping and muscular weakness, these symptoms could be a sign of a stroke.

What is the most common cause of irregular heartbeat?Common triggers for an arrhythmia are viral illnesses, alcohol, tobacco, changes in posture, exercise, drinks containing caffeine, certain over-the-counter and prescribed medicines, and illegal recreational drugs.
How often is too often for irregular heartbeat?To make sure your palpitations are not a sign of something more serious, let your healthcare provider know if: You experience new or different palpitations. Your palpitations are very frequent (more than 6 per minute or in groups of 3 or more)
How long can you have an irregular heartbeat?paroxysmal atrial fibrillation – episodes come and go, and usually stop within 48 hours without any treatment. persistent atrial fibrillation – each episode lasts for longer than 7 days (or less when it's treated) permanent atrial fibrillation – when it's present all the time.
Can you live with an irregular heartbeat?You can certainly live a happy, healthy life with an irregular heartbeat. However, it's always a good idea to check with your doctor when you're experiencing new symptoms or discomfort.
