ECG example 7. Sinus rhythm. Relatively large T-waves in V2-V3, with ST-segment elevations. Relative to the R-waves, T-waves are too large and pointed (differential diagnoses are considered below). ECG examples. Click to zoom. Overview of the normal electrocardiogram (ECG) ...
Objective: To investigate the agreement between perceived heart rhythm and the ECG-registered heart rhythm, as well as between symptoms and the ECG after direct current (DC) cardioversion of atrial fibrillation (AF). Methods: Consecutive patients with symptomatic AF subjected to DC cardioversion were...
The latter looks at your heart rhythm from multiple views (one for each of the connected leads) and can detect heart attacks. If the Apple Watch ECG shows AFib, the responsibility is on the individual to get it further checked on by a physician and perhaps take a more advanced...
