Is the Apple Watch reliable at detecting tachycardia and bradycardia? I am a 38 year old woman who notices ocassional spikes in my BPM of 150 to 205 as well as ocassional drops from 59 to 30. Is this something to be concerned about?
Those values seem extreme. Do you verify them by taking a manual pulse? A blood pressure cuff, a pulse oximeter or a Kardia EKG monitor will also give cross checks.
