## Resource

What can nine carefully selected studies teach us about the changing practice of cardiac electrophysiology? In EP Edge® Journal Watch Issue 34, August 2026, Dr. Sharma provides a clinically focused review of emerging evidence across atrial fibrillation, pulsed field ablation, implantable cardiac devices, sudden death prevention, resuscitation, occupational radiation safety, and postural orthostatic tachycardia syndrome. This episode examines whether transvenous and subcutaneous ICD shocks produce different patterns of myocardial injury; the incidence and clinical meaning of migraine following pulsed field ablation; whether routine mechanical CPR improves meaningful survival after out-of-hospital cardiac arrest; and why hemolysis and renal effects may differ among PFA platforms and workflows. Dr. Sharma also explores the FINE-HEART analysis of finerenone and sudden death, the LOSE-AF randomized trial of weight loss in older patients with persistent atrial fibrillation, occupational radiation exposure during pregnancy, the prognostic significance of skin thickness over cardiac implantable electronic devices, and a randomized crossover comparison of ivabradine and propranolol for POTS. Rather than simply reciting percentages and P values, the discussion explains why each study was undertaken, how it was designed, what its principal statistical findings mean, where uncertainty remains, and how the results might—or might not—affect clinical practice. Each analysis concludes with the EP Edge take: a practical interpretation for physicians, trainees, nurses, allied professionals, and others caring for patients with heart-rhythm disorders. The episode also previews the early September 2026 arrival of EPEdge.org and the EP Edge app. Built around Knowledge · Access · Humanity, t…
