Ectopic heartbeatPVB (premature ventricular beat); Premature beats; PVC (premature ventricular complex/contraction); Extrasystole; Premature supraventricular contractions; PAC; Premature atrial contraction; Abnormal heartbeat
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:
- Premature ventricular contractions (PVC)
- Premature atrial contractions (PAC)
