[29] In another study, a prolonged P wave interval of >120 ms was associated with higher risk of stroke; [40] atrial late potentials (using signal-averaged ECG) were the strongest predictor ...

24-h ECG, signal-averaged ECG and 2-D and Doppler echocardiography. Results 12-Lead ECG was abnormal in 62% of ARVC patients versus 7.5% of athletes and 2.5% of controls (p<0.0001). Ventricular ...

P area and signal-averaged P wave late atrial potential are strong predictors of AF incidence and possibly of stroke incidence. ECG left ventricular hypertrophy is strongly associated with stroke ...

Non-Invasive Tests. Non-invasive tests include an electrocardiogram (ECG or EKG), stress test, echocardiogram, Holter monitor, event monitor, signal-averaged ECG, tilt test, T-wave alternans test, and ...
