As wearable technology becomes more common in daily life, cardiologists are finding new clinical value in devices that many patients already own. Lori Tam, M.D., a cardiologist at Providence Heart Institute, says smartwatches can play an important role in heart care — particularly when it comes to detecting abnormal heart rhythms.
For patients who experience palpitations, flutters or irregular heartbeats, capturing data at the right moment can be challenging. Symptoms often resolve before patients reach a doctor’s office or emergency department. Smartwatches equipped with ECG technology can fill that gap.
“I find them most helpful when patients can use it [smart watches] to monitor their heart rhythm,” Dr. Tam says. “It's helpful to capture the ECG when it's happening.”
Some smartwatches allow patients to record an ECG in real time and share it directly with their physician for review. This can provide cardiologists with valuable information that supports more accurate diagnoses and treatment planning.
“So having the ability to check your ECG in real time as it's happening can be very helpful for your doctor to help you diagnose your rhythm issue if there is any in your heart,” Dr. Tam says.
GLP-1s and heart health
In addition to wearable technology, Dr. Tam also addresses questions patients often raise about weight loss medications, specifically GLP‑1 receptor agonists, and their relationship to heart health. Studies have shown cardiovascular benefits in patients with existing heart disease, including those with plaque-related blockages or heart failure.
From a cardiology perspective, Dr. Tam says most patients can safely take these medications, though side effects may limit their use in some cases.
Together, innovations in wearable technology and ongoing research into medications are helping cardiologists personalize care and improve outcomes. Dr. Tam emphasizes that while technology can be powerful, it works best when paired with expert guidance and strong patient‑provider communication.
At Providence Heart Institute, our clinicians and caregivers continue to evaluate new tools that help patients better understand — and protect — their heart health.
