ABSTRACT
Objective Study the differential diagnosis value of the axis of "no man's land" in wide QRS complex tachycardia.Methods Retrospectively analyse the axis of "no man's land" in 137 patients with wide complex tachycardia who had undergone intracardiac electrophysiologic studies,use the algebraic sum of the deflections in leads I and III to plot the QRS axis,to observe the rule of arrhythmia of "no man's land" appearance.Results Eighteen of 137 patients who had wide complex tachycardia had the axis of "no man's land",among which 16 patients had left idiopathic ventricular tachycardia,and 2 patients had wide complex supraventricular tachycardia they had accessory pathway conduct anterogradely.Conclusion The axis of "no man's land" is helpful in differential diagnosis of ventricular and supraventricular tachycardias with abberency or bundle branch block.
