Circulation: Arrhythmia And Electrophysiology On The Beat

Dr. Wang:            Welcome to the monthly podcast, On the Beat, for Circulation: Arrhythmia and Electrophysiology. I'm Dr. Paul Wong, editor-in-chief, with some of the key highlights from this month's issue.                                 In our first paper, Jeremy Wasserlauf and associates compare the accuracy of an atrial fibrillation sensing smartwatch with simultaneous recordings from an insertable cardiac monitor.                                 The authors use smart rhythm 2.0, a convolutional neuro-network, trained on anonymized data of heart rate, activity level and EKGs from 7500 AliveCor users.                                 The network was validated on data collected in 24 patients with insertable cardiac monitor, and a history of paroxysmal atrial fibrillation who simultaneously wore the atrial fibrillation sensing smart watch with smart rhythm 0.1 software.                                 The primary outcome was sensitivity of the atrial fibrillation sensing smart watch for atrial fibrill
