About ECG+ | Analyzer for QTc & HRV
ECG+ integrates with Apple Health to unleash the greatest power of your Apple Watch ECG, by analyzing and calculating intervals like QT/QTc, PR or QRS, and heart rate variability (HRV) out of your ECG data. QT/QTc are critical measurements linked to life-threatening arrhythmias. HRV is widely considered one of the best objective metrics for physical fitness and determining your body’s readiness to perform.
HRV refers to the variation in time between successive heartbeats, which is an indicator of the health of the autonomic nervous system. QT interval refers to the time it takes for the heart to recharge between beats, which is important for assessing cardiac health.
In the ECG+ app, you can do many things about your ECG recordings from Apple Watch ECG -
1. HRV Trends - with HRV trends you can learn your health level changes. A up hill trend means a better physical fitness level and a down hill indicates you should pay more attention to your overall health. With QT trends you can monitor closely your QT intervals over a period of time and seek healthcare attention whenever a prolonged QT is identified automatically.
2. Measure QT and calculate QTc - ECG+ app automatically identify and measure QT for you, and you can choose one out of 6 QTc formulas to do the QTc calculation
3. Long QTc warning - the app automatically calculates and shows a long QTc warning if a QTc is exceeding the normal range (normal range is based on gender)
4. ECG report - ECG+ app provides a much more comprehensive report than the default report from Apple Health, and it includes R-R markings, HRV Poincaré plot, 6 intervals, heartbeat signatures and more, with which you can get a much clearer picture of how your heart is functioning
[Disclaimer]
All findings associated to the ECG readings in the ECG+ app, including but not limited to PAC/PVC detection, Long QT detection and HRV calculation, do NOT suggest diagnosis. It only provides more information for you with which to consult your doctor, not as a substitute to doing so.
