WebDr. Burns explains, “EKGs are not typically looking for arrhythmias. Therefore, unlike the longer rhythm strips or event monitors, the EKG need only be long enough to capture only several heart complexes. “The EKG is looking at the electrical flow through heart muscle. If this is abnormal, it will be apparent in any one heartbeat.”. WebUsually very small or absent. R wave: first upward deflection of the QRS complex. Upward deflections occurring after an S wave are noted by a "prime mark" such as R' S wave: the first downward deflection occurring after the R wave. A monophasic negative QRS complex is called QS.
