Temporary cardiac pacing induced electrocardiographic changes simulating myocardial infarction

Suresh Kumar Behera, Akshaya Kumar Samal, Akshyaya Kumar Pradhan

Abstract


Temporary transvenous pacing is an immediate lifesaving measure in patients with Stokes-Adams syndrome and in patients with symptomatic bradycardia. Bradyarrhythmias are known to occur in acute myocardial infarction. But in a paced heart, it is difficult to diagnose myocardial infarction from electrocardiogram (ECG) because pacemaker rhythm causes distortion of natural wave forms. On the other hand, remarkable T wave inversions and ST depressions do occur in the ventricular paced ECG as secondary changes. The case report describes a patient who developed profound de novo T wave inversions and ST depressions in the unpaced ECG following temporary transvenous pacing simulating MI.
