Can Apple Watch ECG detect PVCs?
In participants with an irregular pulse notification on the Apple Watch and no AF observed on ECG patch, atrial and ventricular arrhythmias, mostly PACs and PVCs, were detected in 40% of participants. The Apple Watch Series 7, due to be released sometime this fall, does not feature any new health sensors.
What does A-Fib look like on a heart monitor?
In A-Fib you will see many “fibrillation” beats instead of one P wave. A characteristic sign of A-Fib is the absence of a P wave in the EKG signal. The next large upward spike segment, the QRS Complex, is formed when the ventricles (the two lower chambers of the heart) are contracting to pump out blood.
Is Apple Watch ECG FDA approved?
Apple has landed a new FDA clearance for an updated version of its ECG feature, allowing the tool to add a category called A-Fib with high heart rate. This comes a little over two years after Apple first landed a De Novo clearance for its first version of the ECG reading.
