Evaluation and Management of Arrhythmias in Ischemic Cardiomyopathy.

Atrial and ventricular arrhythmias are highly comorbid with ischemic cardiomyopathy (ICM) and are associated with worsening symptoms, morbidity, and mortality. This review will discuss the pathophysiology, evaluation, and treatment of each arrhythmia in ICM with a focus on novel evaluation strategies and catheter-directed interventions. For atrial fibrillation /atrial flutter, recent studies have demonstrated mortality and symptom benefit with early rhythm control with catheter ablation. With respect to ventricular tachycardia, scar characterization is being investigated to change primary prevention and novel ablation technologies and strategies are being explored.
