What Your Smartwatch Can—and Can’t—Tell You About Your Heart
Smartwatches can detect irregular rhythms, measure heart rate, and even record an ECG—but they’re not foolproof.
As Dr. Patrick Kee, cardiologist at Vital Heart & Vein, shared with Parade.com, here are a few things to keep in mind:
They don’t monitor continuously unless prompted
ECGs require you to remain still for accuracy
Readings can be “inconclusive” or inaccurate during motion or outside normal ranges
Sensors may be affected by sweat, tattoos, skin tone, or a loose fit
Smartwatches are powerful tools, but they don’t replace medical-grade equipment. If you’re getting frequent alerts—or have symptoms—follow up with a cardiologist.
