ECG and arrhythmia classification
ECG and arrhythmia classification : Narrow complex arrhythmias (arise above bifurcation of the bundle of His) – QRS duration <0.1s (2.5 small squares) Broad complex arrhythmias (arise from ventricles or are conducted abnormally from a site above the ventricles so that a delay occurs (rarer). QRS duration is >0.1s (2.5 small squares).
