Wearable technology makes this possible by continuously tracking heart rhythm, sleep, stress and recovery, revealing how daily choices affect long-term cardiovascular health.

“Wearable technology is changing how we detect and monitor heart health,” said Dr. Ali Sovari, cardiac electrophysiologist at Dignity Health. “It provides real-world, continuous data that often reveals patterns we cannot capture during a short clinic visit.”

Unlike traditional tests that offer brief snapshots, wearables provide continuous monitoring—more like watching the full movie than a single scene—allowing earlier detection of intermittent arrhythmias, stress-related changes and sleep abnormalities.

What Wearables Track

Wearables like smartwatches, smart rings and fitness trackers, are becoming increasingly sophisticated gathering useful data that can provide insights into our cardiovascular health. They can monitor several key metrics including:

  • Heart rate and recovery
  • Heart rate variability (autonomic balance)
  • Physical activity and movement
  • Sleep quality and patterns
  • Single-lead ECGs for rhythm detection (e.g., atrial fibrillation)

Turning Data Into Action

The true value of wearable technology isn't just in the data it collects, but in what we do with that information. It can increase awareness of our habits, guide lifestyle changes, detect early warning signs and improve patient–clinician discussions.

The Future

As wearables evolve to include more advanced monitors and become more readily available, they are shifting cardiovascular care toward prevention—empowering people to engage with their heart health daily and make informed, proactive decisions for a healthier future.
