Web15 feb. 2014 · 2. The Six Second Method: Get 6 seconds of ECG tracing (i.e. 30 big boxes) and count the number of R waves that appear within that 6 second period and multiply by 10. Another version of this is the 10 second method (i.e. 50 big boxes) and count the number of R waves that appear within that 10 second period and multiply by 6. … WebThe QRS duration is generally <0,10 seconds but must be <0,12 seconds. If QRS duration is ≥ 0,12 seconds (120 milliseconds) then the QRS complex is abnormally wide (broad). This is very common and a significant finding. The reason for wide QRS complexes must always be clarified.
