Definition of Ectopic heartbeat
Ectopic heartbeat is an irregularity of the heart rate and heart rhythm involving extra or skipped heartbeats.
Causes, incidence, and risk factors
Ectopic heartbeats are small variations in an otherwise normal heartbeat that causes an irregular pulse. They may occur without an obvious cause and are usually harmless.
Signs and tests
A physical examination may show an occasional, irregular pulse, but if the ectopic beats do not occur frequently, your doctor may not detect them during a physical exam.
Most ectopic heartbeats do not require treatment. The condition is treated if your symptoms are severe or if the extra beats occur very frequently.
Ectopic heartbeats are generally benign, requiring no treatment. Occasionally, they may indicate an increased risk for other cardiac arrhythmias.
