Ectopic heartbeats are small changes in a heartbeat that is otherwise normal. These changes lead to extra or skipped heartbeats. Often there is not a clear cause for these changes. They are mostly harmless.
The two most common types of ectopic heartbeats are:
PVB (premature ventricular beat); Premature beats; PVC (premature ventricular complex/contraction); Extrasystole
Sometimes ectopic heartbeats are seen with:
Ectopic heartbeats are rare in children without heart disease that was present at birth (congenital). Most extra heartbeats in children are premature atrial contractions (PACs). These are almost always harmless.
In adults, ectopic heartbeats are common. They are most often due to PACs or PVCs. Your doctor should look into the cause, but no treatment is needed most of the time.
Note: There may be no symptoms.
A physical exam may show an occasional uneven pulse. If the ectopic heartbeats do not occur very often, your doctor may not find them during a physical exam.
Blood pressure is most often normal.
The following tests may be done:
The following may help reduce ectopic heartbeats for some people:
Most ectopic heartbeats do not need to be treated. The condition is only treated if your symptoms are severe or if the extra beats occur very often.
The cause of the heartbeats, if it can be found, may also need to be treated.
In some cases, ectopic heartbeats may mean you are at greater risk for serious abnormal heart rhythms, such as ventricular tachycardia.
