WebIn this video, I demonstrate how to use the Big Box Method (AKA "the 300 method") to determine the heart rate on an ECG. Check out the 6 second method too - ... WebNote that the paper speed is 50 mm/s (1 large box equals 100 ms). The hallmark of both RBBB and LBBB is the QRS duration which is by definitions 120 ms or longer. The distinction between RBBB and LBBB is simple, as illustrated in this figure. ECG criteria for right bundle branch block (RBBB) QRS duration ≥0,12 seconds.
