Abstract

Premature ventricular contractions (PVC) are a type of ventricular arrhythmias, occurring as a result of formation or reentry of an abnormal impulse in the ventricular myocardium or in the Purkinje system. PVC occurs commonly in healthy individuals and is observed in 1%-4% of the population. Several lifestyle factors like stress levels, caffeine, drugs, alcohol, nicotine, sleep, and physical exercise have been implicated in increasing the risk. Caffeine and drugs precipitate heightened cardiac stimulation, precipitating PVCs. Excessive alcohol and nicotine disturb the electrical pathways resulting in PVCs. Higher rates of PVCs have been associated with obesity. Individuals with insomnia and increased stress levels are also at an increased risk due to an imbalance in the autonomic system. Exercise is known to induce PVCs, including in healthy, asymptomatic individuals. Modification of these factors can decrease PVC risk. This article aims to provide a comprehensive review of the effects of lifestyle factors on PVC.
