Heart Monitor 24

A standard ECG recording lasts 30 seconds — but your heart doesn't stop being interesting after half a minute. Heart Monitor 24 connects to your Polar H10 chest strap and records continuous, high-resolution ECG data for hours or even a full day, so you can finally see what's happening between those brief snapshots. Clinical recording equipment costs $3,000 or more. A Polar H10 costs around $100 and is available worldwide. Heart Monitor 24 turns it into a 24-hour ECG recorder you can wear during sleep, exercise, work, or rest — capturing the moments that short recordings always miss. — SEE EVERY HEARTBEAT IN DETAIL — Heart Monitor 24 captures the full electrical signal at 130 Hz — the highest quality available from a consumer chest sensor.
