Ectopic heartbeat is an irregularity of the heart rate and heart rhythm involving extra or skipped heartbeats.
Causes
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.
Sometimes they are associated with chemical (electrolyte) problems in the blood, which need treatment. They can also happen with ischemia caused by a decrease in blood supply to the heart.
Ectopic beats
may be caused or made worse by excessive
smoking,
alcohol consumption, caffeine, certain medications such as stimulants, and some illicit
drugs.
Ectopic beats are rare in children who do not have congenital heart disease. Most extra heartbeats in children are premature atrial contractions (PACs), which are almost always benign.
In adults, ectopic beats are common. Their causes should be investigated even if it turns out that no treatment is needed.
Symptoms
Symptoms include:
Feeling your heart beat (palpitations)
Feeling like your heart stopped or skipped a beat
Feeling of occasional, forceful beats
Note: There
may be no symptoms.
