Acute Inferior Wall ST Segment Elevation Myocardial Infarction Caused Atrial Lead Dysfunction Reversed by Primary Percutaneous Coronary Intervention

A Case Report

Abstract

The mechanism of atrial lead dysfunction varies in patients receiving pacemaker implantation and this needs to be investigated, especially when the causes are reversible. We report and discuss a 76-year-old female who had atrial lead dysfunction caused by acute myocardial infarction and who was recovered after primary percutaneous coronary intervention. The sequential electrocardiographic changes were demonstrated and the possible mechanisms were discussed.
