Connect IQ Watch App

ECG Waveforms on Your Wrist.

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.

Real-Time ECG Wave Simulator

ECG STREAM (130Hz)
Live HR: 62 bpm rMSSD: 74.2 ms Status: STREAMING

Precision Cardiac Monitoring

Allows advanced self-coached athletes to verify heart rhythm health, check HRV, and inspect raw signals.

Raw ECG Visualization

Directly displays the raw electrical micro-volts of your heartbeat at a high-frequency sampling rate (130Hz), rendering a continuous, clear oscilloscope-style wave.

Millisecond RR Intervals

Bypasses standard heart rate averaging to record individual millisecond-accurate R-to-R intervals directly from the Polar H10 internal processor.

Live HRV Analytics

Computes live heart rate variability (HRV) indices, including rMSSD, helping you evaluate autonomous nervous system stress and recovery levels in real-time.

Direct Bluetooth Connectivity

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.

Pairing Process

  1. Wear your Polar H10 strap (moisten the electrodes for signal clarity).
  2. Launch the Polar H10 ECG watch app on your Garmin device.
  3. The watch will automatically scan for nearby Bluetooth heart rate sensors.
  4. Select your Polar H10 sensor ID from the menu. Once paired, the ECG sweep line will immediately begin drawing.
