Polar H10 ECG is a specialized Connect IQ watch application that connects directly to a Polar H10 chest strap using Bluetooth Low Energy (BLE). It captures and displays raw, real-time electrocardiogram (ECG) wave patterns, giving you hospital-grade cardiac visual feedback and instantaneous HRV metrics on your watch.
Allows advanced self-coached athletes to verify heart rhythm health, check HRV, and inspect raw signals.
Directly displays the raw electrical micro-volts of your heartbeat at a high-frequency sampling rate (130Hz), rendering a continuous, clear oscilloscope-style wave.
Bypasses standard heart rate averaging to record individual millisecond-accurate R-to-R intervals directly from the Polar H10 internal processor.
Computes live heart rate variability (HRV) indices, including rMSSD, helping you evaluate autonomous nervous system stress and recovery levels in real-time.
Standard Garmin watches only receive high-level average heart rate packets. This custom application implements Polar's proprietary BLE SDK protocol using Garmin's Bluetooth Low Energy module.
By connecting to the Polar H10 directly as a peripheral device, the app unlocks high-frequency streaming of raw biosignals, turning your watch into a portable electrocardiograph.
Ideal for athletes checking for premature ventricular contractions (PVCs), verifying rhythm stability under load, or checking precise morning autonomic recovery states.
