By definition, a wide complex tachycardia is a heart rhythm with a QRS duration ≥ 120 ms (0.12 s) and a ventricular rate ≥ 100.
When this criteria is met, and the the rhythm is regular (no variability in the R-R interval) then it's a regular wide complex tachycardia. more

There seems to be a lot of confusion with regard to wide complex tachycardias.
For some reason, health care providers of all ranks and stripes forget the most basic rule.
If it's a wide complex rhythm (fast or slow) it's ventricular until proven otherwise! more |
