WebSo now it is possible to break down the QRS complex into 3 distinct waves: Q wave representing septal depolarisation; R wave representing ventricular depolarisation; S wave representing depolarisation of the Purkinje fibres. WebResults: Retrospectively, hypokalemia, cardiac troponin T and conductance abnormalities on ECG were significantly and independently associated with QTc prolongation. A prolonged QTc was associated with increased all-cause mortality (HR 2.698 (95% CI 1.032–7.055), p=0.043), however, this association was no longer significant when corrected for ...

This test gives … WebThe T wave on the ECG is the positive deflection after the QRS complex. It represents the repolarization of the ventricular myocardium. To understand the T wave, let’s first briefly go over depolarization and repolarization. Both of these processes represent a shift in the electrical potential and ions of the cells. landgut papenhausen

WebThe QRS Complex. The second wave is the QRS complex. Typically this complex has a series of 3 deflections that reflect the current associated with right and left ventricular depolarization. By convention the first deflection in the complex, if it is negative, is called a Q wave. The first positive deflection in the complex is called an R wave.
