1.	When the self-triggering impulse does not arrive at the AV node and travels a different and slower path over the ventricles, the QRS becomes widened and is classified as ___________(a) Ectopic beat(b) Ventricular-ectopic beat(c) Ventricular beat(d) Atrio-ventricular beatI had been asked this question during a job interview.Origin of the question is Video Printers in chapter Recording System of Biomedical Instrumentation
Answer» Right answer is (b) VENTRICULAR-ectopic BEAT Explanation: Sometimes irritation occurs in the ventricles, the self-triggering IMPULSE does not arrive through the node and thus travels a DIFFERENT and slower path in spreading over the ventricles. The QRS wave then becomes widened, and is classified as a ventricular ectopic beat. This ectopic beat is classified from ventricles so it is called as a ventricular ectopic beat.
