    Area of Science:

    • Cardiology
    • Electrophysiology

    Background:

    • Myocardial infarction can lead to complex cardiac arrhythmias.
    • Post-infarction complications require careful monitoring and management.

    Observation:

    • A 73-year-old male presented with fatigue and hypotension six weeks post-myocardial infarction.
    • ECG revealed sustained tachycardia with a right bundle branch block.
    • His bundle electrogram demonstrated a complete heart block.

    Findings:

    • The patient experienced a complete heart block following an inferior myocardial infarction.
    • Intravenous procainamide administration resulted in successful rhythm conversion.
    • Symptoms of fatigue and hypotension resolved, with blood pressure normalizing.
