The Role of Wearable Technology in Heart Health Wearable tech is designed to monitor physiological data and provide actionable insights to users. For heart health, these devices use advanced sensors to track metrics like heart rate, blood oxygen levels, and even irregular heartrhythms.
ECG waveform Cardiomatics catalog of ECG events: Sinus rhythm – the normal heartrhythm is the sinus rhythm generated by the physiological pacemaker, the sinus node. Sinus tachycardia – sinus rhythm above 100 bpm is a sinus tachycardia. AFIB/AFL – atrial fibrillation or atrial flutter episodes.
In other words, if the QT is less than 1/2 the RR (QT non -prolonged) and the heart rate is above about 60 beats a minute, you can confidently say the QT is not prolonged. 3) At heart rates below 60, far more caution is due. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval.
Similar-looking wide beats #7,13,14 must also be aberrantly conducted supraventricular impulses — and since P waves are lost after beat #6 and subsequent R-R intervals are irregular — beats #7-thru-16 constitute a run of rapid AFib.
