How is the rise of arrhythmia-detecting devices like Apple Watches playing out in emergency departments across the country?
In this Dec. 7, 2017, file photo, AliveCor president and CEO Vic Gundotra rests his thumb on a wristband sensor to check his heart rate in Mountain View, Calif.Paul Chernoff was in the middle of a Zoom call this past June when his Apple Watch sent him an alert.
The cardiologist recommended an electrocardiogram , but there was no reason for Chernoff to stay in the hospital to wait for it. He had no major risk factors for the big worry with Afib -- having a stroke -- and the arrhythmia likely was temporary and would resolve on its own. One of the most frequent complaints he sees in the ED is palpitations, "which could mean anything," he said. If someone who had palpitations earlier now shows a normal EKG in the ED, McGann can go back and look at Apple Watch data.
"The downside here is false positives," McGann said. "The downstream effects are cost and time for yourself, resource utilization, overtesting, and things like that." "If someone is having crushing chest pain or they are having difficulty breathing, sure, then an ED visit is likely appropriate," he said.
For instance, Marcus recently performed an ablation for premature ventricular contractions on a symptomatic patient. During a routine follow-up, the patient said she felt better but intermittently felt a bit off. When Marcus reviewed her Apple Watch data during those vague symptoms, there was no evidence that her PVCs had returned.
