The Frontier X3 does not display or provide an ECG output. ECG is available in our FDA-cleared medical device, the
Frontier X Plus.
The Frontier X3 still records the ECG signal. Your heart rate, HRV, strain, breathing rate, body shock, step cadence, calories, stress, training load and sleep staging are all derived from it, with unchanged accuracy. What the device does not do is show, export or stream the ECG trace itself.
