Well if you notice, V 2 to V 6 are almost identical; this makes us think that the technician who performed the test had some serious lead placement problems. Remember, leads I and V 6 should be identical. The qR' complex develops in patients who have an RBBB and an old anteroseptal MI; hence, the Q wave.

WebbWhat does a small Q wave mean? A small Q wave was defined as any negative deflection preceding the R wave in V(2) or V(3) with 40-ms duration and 0.5-mV amplitude, with or without a small (0.1-mV) slurred, spiky fragmented initial QRS deflection before the Q wave (early fragmentation).ECG and coronary angiographic findings were analyzed. WebbAn effective drilling fluid removal is necessary to achieve an efficient cementing in oil and gas industry, i.e., it is ideal that all the drilling fluid is displaced by the cement slurry.
