Qrs wave form
WebAug 18, 2016 · A complex consists of five waveforms labeled with the letters P, Q, R, S, and T. The middle three letters—Q, R, and S—are referred to as a unit, the QRS complex. ECG tracings represent the conduction of electrical impulses from the atria to the ventricles. (See ECG waveform components .) ECG waveform components WebQRS complex is a group of waves seen on an electrocardiogram, representing ventricular depolarization. The QRS complex is sometimes called the QRS wave. QRS wave in …
