Ectopic beat is a disturbance of the cardiac rhythm frequently related to the

heart muscle ordinarily responsible for impulse formation (i.e., the sinoatrial node). An ectopic beat can be further classified as either a premature ventricular contraction (PVC), or a premature atrial contraction (PAC).[1]

Some patients describe this experience as a "flip" or a "jolt" in the chest, or a "heart hiccup", while others report dropped or missed beats. Ectopic beats are more common during periods of psychological stress, exercise[2] or debility; they may also be triggered by consumption of some food like carbohydrates, strong cheese, or chocolate.[citation needed]

It is a form of

cardiac arrhythmia in which ectopic foci within either ventricular or atrial myocardium, or from finer branches of the electric transduction system, cause additional beats of the heart. Some medications may worsen the phenomenon.[citation needed

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. Ectopic beats are a type of

cardiac arrhythmias, which is a variety of cardiac abnormalities relating to rate or rhythm of the cardiac cycle.[3]

Ectopic beats may become more frequent during
