Slurred or notched downstroke of the S wave in V1 or V2 favors VT. Duration of onset of the QRS complex to peak of QS or S wave > 60 ms favors VT. These morphology criteria are hard to memorize ...
The sum of time–voltage QRS areas in the 12-lead electrocardiogram (ECG) has outperformed other 12-lead ECG indices for detection of left ventricular hypertrophy (LVH). We assessed indices of ...
An "Osborne wave" characterized by a notch in the downward portion of the R wave in the QRS complex. Low voltage. Bradycardia: This can be sinus bradycardia, junctional bradycardia, atrial ...
