WebOct 12, 2024 · A broad QRS complex occurs if there is an abnormal depolarisation sequence – for example, a ventricular ectopic where the impulse spreads slowly across the myocardium from the focus in the ventricle. In contrast, an atrial ectopic would result in a narrow QRS complex because it would conduct down the normal conduction system of … WebThe QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing. It corresponds to the depolarization of the right and left ventricles of the heart and contraction of the large ventricular muscles.

Narrow complexes (QRS < 100 ms) are supraventricular in origin. Broad complexes (QRS > 100 ms) may be either ventricular in origin, or due to aberrant conduction of supraventricular complexes (e.g. due to bundle …
WebA broad QRS (or wide QRS) complex (width greater than .12 seconds) is known as a broad QRS tachycardia. Wide-complex tachycardias can be seen in two general forms: monomorphic and polymorphic. These can often be distinguished from other tachycardic mechanisms by the width, shape, and consistency of the QRS complex (it may be either … WebThe main feature of bundle branch blocks is the broadening of QRS complexes.
