Why Measure From The Chest?

Measure At The Source Your heart’s signals are strongest at the chest, giving you more precise readings.

ECG Vs. PPG Chest-worn ECG tracks heart activity directly, unlike wrist PPG, which relies on blood flow changes.

Reduce Noisy Signal Chest placement reduces motion artifacts, giving you cleaner, more reliable data during activity.
