Wellens' Sign and Syndrome Detected With the Home Use of a Novel 12-Lead Electrocardiogram

Wellens' sign is a high-risk electrocardiogram (ECG) pattern associated with proximal left anterior descending artery stenoses and high risk of major adverse cardiovascular events.

A man with transient chest pain remained asymptomatic including with exertion for 48 hours. His friend performs a home 12-lead ECG using a novel, artificial intelligence-enabled device that showed a classic Wellens' Sign Type A, and the man went to a hospital and subsequently received 2 stents in his proximal left anterior descending artery.

The Kardia12L is a Food and Drug Administration-cleared, pocket-sized ECG device that generates an interpreted 12-lead ECG. Devices like Kardia 12L can lead to diagnosis of cardiovascular disease from home and improve outcomes.

This case highlights the utilization of novel technology to facilitate accurate diagnosis.

This case illustrates Wellens' Type A Sign and Syndrome in an asymptomatic patient with a history of chest pain. New technology enables the recording of a diagnostic ECG in high-risk patients anywhere.
