Role of wearable rhythm recordings in clinical decision making—The wEHRAbles project

Abstract

Background: Multiple wearable devices for rhythm analysis have been developed using either photoplethysmography (PPG) or handheld ECG. Hypothesis: The aim of this survey was to assess impact of these technologies on physicians' clinical decision-making regarding initiation of diagnostic steps, drug therapy, and invasive strategies. Methods: The online survey included 10 questions on types of devices, advantages, and disadvantages of wearable devices as well as case scenarios for patients with supraventricular arrhythmias and atrial fibrillation (AF). Results: A total of 417 physicians (median age 37 [IQR 32-43] years) from 42 countries world-wide completed the survey. When presented a tracing of a regular tachycardia by a symptomatic patient, most participants would trigger further diagnostic steps (90% for single-lead ECG vs 83% for PPG, P
