Ectopic beats are considered normal and are not indicative of cardiac pathology. Ectopic beats often remain undetected and occur as part of minor errors in the heart conduction system. They are rarely indicative of cardiac pathology, although may occur more frequently or be more noticeable in those with existing cardiac abnormalities.
Heart disease was excluded after physical examination, chest x-ray, ECG, echocardiography, maximal exercise stress test, right- and left-heart catheterization and coronary angiography. [30] In 122,043 United States Air Force flyers and cadet applicants during approximately 48 seconds of ECG 0.78% (952 males) had PVC within all age groups, but ...
A premature heart beat or extrasystole [1] is a heart rhythm disorder corresponding to a premature contraction of one of the chambers of the heart. Premature heart beats come in two different types: premature atrial contractions and premature ventricular contractions. Often they cause no symptoms but may present with fluttering in the chest or ...
The total number of deaths due to an irregular heartbeat was 37.1% above average in March and 23.1% in April – a sharp jump from 13.7% in January and 9.2% in February.

The cardiac etiologies of palpitations are the most life-threatening and include ventricular sources (premature ventricular contractions (PVC), ventricular tachycardia and ventricular fibrillation), atrial sources (atrial fibrillation, atrial flutter) high output states (anemia, AV fistula, Paget's disease of bone or pregnancy), structural ...
