  2. Premature ventricular contraction - Wikipedia

    en.wikipedia.org/wiki/Premature_ventricular...

    A premature ventricular contraction (PVC) is a common event where the heartbeat is initiated by Purkinje fibers in the ventricles rather than by the sinoatrial node.PVCs may cause no symptoms or may be perceived as a "skipped beat" or felt as palpitations in the chest.

  3. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    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.

  4. Premature heart beat - Wikipedia

    en.wikipedia.org/wiki/Premature_heart_beat

    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 ...

  6. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Premature ventricular beats occurring after every normal beat are termed ventricular bigeminy; PVCs that occur at intervals of 2 normal beats to 1 PVC, or 1 normal beat to 2 PVCs, are termed "PVCs in trigeminy" [13] Groups of three premature ventricular beats are called triplets and are considered a brief run of non-sustained ventricular ...

  7. Bigeminy - Wikipedia

    en.wikipedia.org/wiki/Bigeminy

    For example, in ventricular bigeminy, a sinus beat is shortly followed by a premature ventricular contraction (PVC), a pause, another normal beat, and then another PVC. [1] In atrial bigeminy, the other "twin" is a premature atrial contraction (PAC).

  8. Heart rate turbulence - Wikipedia

    en.wikipedia.org/wiki/Heart_rate_turbulence

    Heart rate turbulence (HRT) is a baroreflex-mediated adjustment of heart rate which acts as a counter-mechanism to premature ventricular contraction (PVC). [1] It consists of a brief speed-up in heart rate, followed by a slow decrease back to the baseline rate.
