Long qrs interval meaning
WebThe T wave can be described by its symmetry, skewness, slope of ascending and descending limbs, amplitude and subintervals like the T peak –T end interval. [1] In most leads, the T wave is positive. This is due to the repolarization of the membrane. During ventricle contraction (QRS complex), the heart depolarizes. WebAlthough QT interval prolongation is one of the most common reasons for drug withdrawal from the market, the overall incidence of drug-induced QT prolongation is difficult to estimate. One study in France estimated that between 5-7% of reports of ventricular tachycardia , ventricular fibrillation , or sudden cardiac death were in fact due to drug …
