Health: New “Digital AI Device” Helps Identify Patients With Atrial Fibrillation (Mayo Clinic)

Mayo Clinic LogoThis small device may change how doctors identify and manage patients with atrial fibrillation, an irregular heart rhythm that increases risk of stroke.

And the past. The device uses artificial intelligence, or AI, to not only determine if a person is in the midst of an episode of atrial fibrillation, but also it can reveal if they’ve had the irregular rhythm before or will have it in the future.

Dr. Paul Friedman and his team trained the device to detect subtle changes in the heart’s electrical signals. Then in a study, they found it can identify patients with episodic atrial fibrillation. Even when they record the heart while the rhythm is normal – something no current wearable heart monitor can do.

That’s because a heart monitor won’t detect atrial fibrillation unless you have an episode while wearing it. But in a matter of moments, the AI device can identify people with atrial fibrillation, even if their heart is in normal rhythm. Then they can get on the right treatment to help prevent life-threatening strokes from happening.

Heart Studies: Alcohol Abstinence For Atrial Fibrillation Reduces Arrhythmia (NEJM)

Abstinence from alcohol reduced arrhythmia recurrences in regular drinkers with atrial fibrillation. 

New England Journal of Medicine

January 2, 2020 Atrial fibrillation is the most common sustained arrhythmia,1 and alcohol is consumed by a majority of U.S. adults.2 The current study showed that among regular drinkers, a substantial reduction in alcohol consumption by patients with symptomatic atrial fibrillation was associated with a reduction in recurrence of atrial fibrillation and a reduced proportion of time spent in atrial fibrillation. Earlier meta-analyses showed that alcohol was associated with a dose-related increased risk of incident atrial fibrillation, with increased risk observed even among drinkers who consumed as few as 7 drinks per week.8 Current trends show a rise in alcohol consumption among adults older than 60 years of age,2coupled with greater prevalence of atrial fibrillation in this age group. The present study, with participants having an average intake of approximately 17 drinks per week at baseline, suggests that consumption at these levels may contribute to atrial fibrillation.
