Dr Paul Wang:                   Welcome to the monthly podcast, On the Beat, for Circulation: Arrhythmia and Electrophysiology. I'm Dr Paul Wang, editor-in-chief, with some of the key highlights from this month's issue.                                                 In our first article, Daniel Alyesh, Konstantinos Siontis and associates described myocardial calcifications in patients with ischemic cardiomyopathy undergoing ventricular tachycardia ablation in comparison to a control group of patients without ventricular tachycardia. They found that in 56 consecutive post-infarction patients, myocardial calcifications were identified in 39 or 70% of post-infarction ventricular tachycardia patients compared to 6 or 11% of patients without ventricular tachycardia. A calcification volume of 0.538 centimeters cube distinguished patients with calcification-associated ventricular tachycardia from patients without calcification-associated ventricular tachycardias; area under the curve, 0.87; sensitivity, 0.87; spec
