Hiatal Hernia and Cardiac Arrhythmias

Clinical Evidence and Diagnostic Approach

The World Journal of Emergency Surgery notes that while tachycardia can be a sign of strangulated hernia, a surgical emergency, this typically presents with fever, continuous abdominal pain, and signs of systemic inflammatory response syndrome (SIRS) 1
The American College of Radiology recommends imaging with fluoroscopy, such as biphasic esophagram or upper GI series, as the most useful test for diagnosing hiatal hernia and determining its size 2

Surgical repair of large symptomatic hernias can resolve associated arrhythmias, with documented resolution of premature ventricular contractions and ventricular tachycardia post-operatively, although the exact mechanism and strength of evidence are not specified in the provided citations 1
