Weight loss interventions, including bariatric surgery and dietary changes, reduce the risk of ventricular arrhythmias and sudden cardiac death in obese patients by correcting electrophysiological abnormalities.
Losing weight through diet or surgery is a powerful way to protect your heart from dangerous rhythms. It doesn't just change your appearance; it physically corrects the electrical signals in your heart (shortening the QT interval) and reduces the metabolic stress that triggers arrhythmias. Discuss weight management strategies with your cardiologist.
Various studies have demonstrated that weight loss, either by diet or bariatric surgery, shortens QTc and reduces QT/QTc dispersion in obese patients, reduces BCAA plasma levels, restores cardiac electrical dysfunction, and ameliorates the risk of arrhythmias such as atrial fibrillation.
