  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. PVCs do not usually pose any danger. [1]

  3. Ectopic beat - Wikipedia

    en.wikipedia.org/wiki/Ectopic_beat

    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.

  4. Roemheld syndrome - Wikipedia

    Treatment of the primary gastroenterological distress is the first concern, mitigation of gastric symptoms will also alleviate cardiac distress. Anticholinergics, magnesium, or sodium (to raise blood pressure) supplements

  5. Arrhythmia - Wikipedia

    en.wikipedia.org/wiki/Arrhythmia

    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 tachycardia (NSVT); if the grouping lasts for more than 30 seconds, it is considered sustained ...

  6. Palpitations - Wikipedia

    en.wikipedia.org/wiki/Palpitations

    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 ...

  8. Premature heart beat - Wikipedia

    en.wikipedia.org/wiki/Premature_heart_beat

    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 a skipped beat. They typically have no long term complications. They most often happen naturally but may be associated with caffeine, nicotine, or ...

  9. Hypertrophic cardiomyopathy - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_cardiomyopathy

    HCM can be distinguished from other inherited causes of cardiomyopathy by its autosomal dominant pattern, whereas Fabry disease is X-linked, and Friedreich's ataxia is inherited in an autosomal recessive pattern. [10] Treatment may depend on symptoms and other risk factors. Medications may include the use of beta blockers, verapamil or ...
