In the remaining studies, widened QRS complexes were most commonly attributed ... time from last drug exposure to first noted electrocardiogram abnormality or clinical evidence of suspected ...

V5 and V6 ST and T wave displacement opposite to the major deflection of the QRS complex A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> 120 ms) would be to ...

This ECG shows atrial fibrillation with an uncontrolled ventricular rate. There are two QRS complexes that become wide in a right bundle branch block pattern. This can occur at fast heart rates ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...
