As a whole, cocaine-associated electrocardiographic abnormalities are well described in the literature (primarily in the form of observational studies, small controlled studies and case reports).
When electrical activity does not conduct through the His-Purkinje system, but instead travels from myocyte to myocyte, a longer time is necessary, and the QRS duration is widened. A widened QRS ...

Ventricular tachycardia refers to a wide QRS complex heart rhythm — that is, a QRS duration beyond 120 milliseconds — originating in the ventricles at a rate of greater than 100 beats per minute.
A faster rhythm is known as accelerated idioventricular rhythm. Ventricular rhythms have a wide QRS complex. The ECG records electrical impulses and provides information about the heart rate and ...
However, Goff would bounce back from the interception, later throwing a nine-yard touchdown pass to former USC wide receiver Amon-Ra St. Brown. St. Brown has now scored a touchdown in seven ...
