A large hiatal hernia causing frequent premature ventricular contractions with bigeminy: A case report and review of literature.

UNLABELLED: Most patients with hiatal hernia (HH) are asymptomatic; however, common symptoms include gastroesophageal reflux disease (GERD) and heart burn. Larger hernia can cause obstruction, ischemia of the bowel, volvulus of the contents of the hernial sac, respiratory distress, and rarely, cardiac abnormalities are also noted. Most reported cardiac abnormalities associated with HH include atrial fibrillation, atrial flutter, supraventricular tachycardia, and bradycardia. We present a rare case of a large HH causing frequent premature ventricular contractions in bigeminy form that resolved with surgical correction of HH and did not recur on subsequent Holter monitoring. We highlight the potential association between HH/GERD and cardiac arrhythmias and reinforce the need to keep HH/GERD as one of the working diagnoses in a patient with cardiac arrhythmia.

LEARNING OBJECTIVE: •Large hiatal hernia can cause several arrhythmias such as atrial fibrillation, atrial flutter, supraventricular tachycardia, bradycardia, and premature ventricular contractions (PVCs).•It is essential to consider hiatal hernia and gastroesophageal reflux disease as one of the differentials in the work up of cardiac arrhythmias including PVCs.
