  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. 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 ...

  4. 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.

  6. Bigeminy - Wikipedia

    en.wikipedia.org/wiki/Bigeminy

    After any premature ventricular contraction there is a pause that can lead to the development of bigeminy. A PVC wavefront often encounters a refractory AV node that does not conduct the wavefront retrograde. Thus the atrium is not depolarized and the sinus node is not reset.

  7. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    Premature ventricular contractions (PVCs), sometimes called ventricular extra beats (VEBs) 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]

  8. Frank–Starling law - Wikipedia

    en.wikipedia.org/wiki/Frank–Starling_law

    Premature ventricular contraction causes early emptying of the left ventricle (LV) into the aorta.Since the next ventricular contraction occurs at its regular time, the filling time for the LV increases, causing an increased LV end-diastolic volume.

  9. Dilated cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Dilated_cardiomyopathy

    Recent studies have shown that those subjects with an extremely high occurrence (several thousands a day) of premature ventricular contractions (extrasystole) can develop dilated cardiomyopathy. In these cases, if the extrasystole are reduced or removed (for example, via ablation therapy) the cardiomyopathy usually regresses.
