Left ventricular hypertrophy can be diagnosed on ECG with good specificity ... representing ventricular depolarization, is increased. Likewise, when the myocardium is abnormally thickened ...

Normally, there is no electrical activity (flat ECG) between ventricular depolarization (reflected by the QRS complex) and repolarization (T wave), corresponding to the ST segment, because all ...

The QT interval is the time from the beginning of the QRS complex, representing ventricular depolarization, to the end of the T wave, resulting from ventricular repolarization. The normal QT ...

Single ventricular premature complexes ... otherwise, sinus depolarization would suppress it 2,3. Figure 2: An ECG obtained from a beagle dog 21 days later, showing six rhythm strips ...
