Can Wearable Tech And AI Really Predict Sudden Cardiac Events Or Is It Still Just Hype?

Every few months, a new smartwatch feature promises to 'predict' heart problems before they strike, from irregular rhythms to ECGs you can record on your wrist. It sounds futuristic, almost too good to be true, and for many people, it raises a real question: can these devices actually warn us about sudden cardiac events, or are we getting swept up in tech-driven optimism?

To understand where the science truly stands, we spoke to Dr Jajati Keshari Padhi, Senior Consultant and Director of Interventional Cardiology, Manipal Hospital, Bhubaneshwar. He explains how wearables and AI are reshaping early detection, where their limitations still lie, and what this means for everyday users trying to stay ahead of heart disease.

How Wearables Are Changing Heart Monitoring

"The way we monitor the health of our hearts is quickly evolving, thanks to wearable tech and AI, offering the possibility to detect some sudden cardiac events early through screening. They can record heart rate variability, detect irregular rhythms like atrial fibrillation, and even generate basic ECG tracings; data that used to be available only in hospitals," explained Dr Padhi.

Paired with AI algorithms, the devices can detect tiny trends and anomalies that may be signs of growing cardiac stress or early warning signals of heart disease. For instance, AI models could process streaming continuous data to notify users or physicians when irregular patterns are detected before heart attack and arrhythmia events.

The Limitations You Should Know About

But for all the promise, technology isn't fool-proof just yet. False positives, inadequate clinical validation, and data interpretation for users still pose important challenges. Wearables are not a substitute for professional diagnostics or medical-grade monitoring.

"Don't fork out for the most expensive devices, thinking they will be what keeps you safe. In other words, they're useful as an early warning system, sounding a wake-up call for medical consultation rather than being used as a stand-alone diagnostic tool," highlighted Dr Padhi.

Bottomline

Dr Padhi concluded, "So it's not just hype; AI-enhanced wearables really are blazing the path for predictive and preventative cardiac care. Yet we can only sustainably prevent sudden cardiac events by developing technologies that are inextricable from medical oversight, rigorous data analysis, and personalised health management."
