Heart Pulse rate detector

Severe arrhythmia pulse waves are unstable, so they can't be detected properly by the senor.
Tips on placing your finger on the sensor:
Place the finger so that the sensor is covered by your fingerprint, not the fingertip. If your fingernail turns white, you are pressing too hard. Try pressing down a bit with your finger first, and then make adjustments until seeing the touch sensor changes to the pulse and small heart icon blinks, then, it demonstrates that your pulse is being registered.
