Massive inferior wall aneurysm presenting with ventricular tachycardia and refractory cardiomyopathy requiring multiple interventions: A case report

Figure 1 12-lead electrocardiograms showing an inferior ST-segment elevation myocardial infarction and ventricular tachycardia respectively. A: 12-lead electrocardiogram one month earlier showing sinus rhythm with a ventricular rate of 90 beats per minute, left axis deviation, pathologic Q waves with 2-3 mm ST-segment elevation in inferior leads (III > II) and avF, and reciprocal ST depression in I and avL; B: 12-lead electrocardiogram showing ventricular tachycardia (VT) with a left bundle branch block morphology, ventricular rate of 150 beats per minute, left superior axis, poor precordial R wave progression, V2 transition suggesting inferoseptal origin of scar-related VT.
