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]
Treatments may include physical maneuvers, medications, electricity conversion, or electro- or cryo-cautery. [citation needed] In the United States, people admitted to the hospital with cardiac arrhythmia and conduction disorders with and without complications were admitted to the intensive care unit more than half the time in 2011.

In people without underlying heart disease and who do not have any symptoms, bigeminy in itself does not require any treatment. If it does become symptomatic, beta-blockers can be used to try to suppress ventricular ectopy. Class I and III agents are generally avoided as they can provoke more serious arrhythmias. [4]
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
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.

People who are determined to be at high risk for palpitations of serious or life-threatening etiologies require a more extensive workup and comprehensive management. [1] Once a cause is determined, the recommendations for treatment are quite strong, with moderate to high quality therapies studied. [1]
Treatments for primary pulmonary hypertension such as prostacyclins and endothelin receptor antagonists can be fatal in people with PVOD due to the development of severe pulmonary edema, and worsening symptoms after initiation of these medications may be a clue to the diagnosis of pulmonary veno-occlusive disease.
