Hyperkalemia Masking ACS - STEMI: ED Enigma

Abstract: Acute coronary syndrome ST segment elevation myocardial infarction with inferior wall myocardial infarction with right coronary artery block (ACS - STEMI - IWMI) usually presents with bradyarrythmias1 due to common blood supply to sinus node2, 3 and hyperkalemia higher than>7.5 meq/L known to cause and present as ventricular fibrillation, sinoatrial and atrioventricular blocks, asystole, complete heart blocks secondary to disordered membrane polarization.4, 5 Here we describe a case who presented to emergency room with junctional bradycardia and had severe hyperkalemia and metabolic acidosis, despite antihyperkalemic measures and metabolic acidosis treatment patient didn?t improve and was found to have ACS ? STEMI
