Delayed overall conduction time to the LV extends the QRS duration to > 120 msġ) Conduction delay means impulses travel first via the right bundle branch (black arrow)Ģ) Septum is activated from right-to-left (yellow arrows)ģ) Overall depolarisation vector is directed towards lateral leads (red arrow).The delay between activation of the RV and LV produces the characteristic “M-shaped” R wave seen in lateral leads The overall depolarisation vector from the right to left ventricle produces tall R waves in lateral leads (I, V5-6) and deep S waves in the right precordial leads (V1-3). Because of its relatively small size (about the size of a watch face), the placement of the AICD does not require major surgery, and recovery time is minimal.SCP-ECG acronym descriptions for super- and subclasses. Septal activation is thus reversed eliminating lateral Q waves tation algorithms promise significant assistance for the medical personnel due to the large. It occurs when a short circuit rhythm develops in the upper chamber of the heart. 61 items A 1246 items B 625 items C 1420 items D 773 items E 815 items F 691 items G 524 items H 804 items I 870 items.
