Abstract
Objective We analyzed the surface ECG of 146 patients with dual atrioventricular nodal pathway and that of 120 patients with concealed W-P-W syndrome,which were confirmed by RFCA during sinus rhythm and tachycardia,and summarized the distinguishing features of ECG to increase the diagnostic accuracy of atrioventricular nodal reentrant tachycardia.Methods We compared the surface ECG in 12 leads during sinus rhythm with tachycardia,and tried to find the relation between the different locations of retrograde P' wave and QRS complex in all leads.Results There was no retrograde P' wave in 30 patients ECG,the occurrence rate was 20.5%.There were 84 patients without retrograde P' wave in limb leads but with rSr' complex in V1 lead,occurrence rate 57.5%;29 patients with pseudos wave and rSr' complex in V1 lead,occurrence rate 19.9%;3 patients with pseudo-q wave,2.1%.Only one patient with concealed W-P-W syndrome appeared rSr' complex in V1 lead.Conclusion The specialty and accuracy of rSr' complex in V1 lead is higher for the diagnosis of dual atrioventricular nodal pathway with supraventricular tachycardia.It is a very useful method in diagnosing dual atrioventricular nodal reentrant tachycardia rapidly and accurately in the surface ECG.关键词
