A Case of Acute Coronary Occlusion in a Morbidly Obese Patient Masked on Electrocardiogram by Low QRS Voltage

J Investig Med High Impact Case Rep. 2020 Jan-Dec:8:2324709620903133. doi: 10.1177/2324709620903133.

Abstract

Timely diagnosis of acute coronary occlusion is essential to avoid chronic cardiac impairment and death. We describe an uncommon case of acute myocardial infarction masked by low QRS voltage secondary to morbid obesity. This case highlights the importance of considering the degree of ST-segment elevation proportionally to the QRS amplitude if there is clinical suspicion of acute coronary occlusion.

Keywords: ST-elevation myocardial infarction; acute coronary syndrome; high BMI; low QRS; masking EKG; morbid obesity.
