Arrhythmias can complicate the course of patients with ST-elevation myocardial infarction. These arrhythmias can include both tachyarrhythmias and bradyarrhythmias. Tachyarrhythmias range from Ventricular premature complexes to life-threatening ventricular tachycardia/ fibrillation. Bradyarrhythmias range from sinus bradycardia to complete heart block. These arrhythmias have the ability to provoke hemodynamic consequences and increase mortality. Tachyarrhythmias are more common with Anterior wall myocardial infarction and bradyarrhythmias are more common with Inferior wall myocardial infarction. We report a case of Mobitz Type 1 (Wenkebach) second-degree atrioventricular block in a patient with Anterior wall myocardial infarction. Angiography showed a significant lesion in Left anterior descending artery, after the first septal and diagonal branch. After the successful percutaneous coronary intervention, this second degree AV block reverted to first degree AV block. To the best of our knowledge, there is no case report describing this association separately.
