Abstract:
Seventy-three year-old male with history of diabetes, hypertension, and chronic kidney disease stage 3 presented with epigastric pain and hyponatremia. ECG showed new ST segment elevation at precordial leads consistent with Cove-type Brugada ECG pattern. Cardiac catheterization revealed non-significant coronary artery stenosis. He experienced pre-syncope and palpitations a year prior to admission with family history sudden cardiac death. Brugada syndrome was diagnosed. Cove-type Brugada ECG pattern and palpitations resolved with corrected sodium to 135.

Types of Arrhythmias
Sinus Node Arrhythmias
Sinus Bradycardia: Originating from the sinoatrial (SA) node, sinus bradycardia involves slower impulses, resulting in a heart rate of less than 60 beats per minute (bpm). Causes include sleep, vagal stimulation, beta-blockers, hypothyroidism,...
