Objective : To explore the diagnostic value of STsegment depression Twave inversion on inferior leads during narrow QRScomplex tachycardia- Methods : We analyzed 12 lead electrocardiograms of 205 patients (112 males) during narrow QRS complex supraventricular tachycardia to evaluate the significance of STsegment depression/T wave inversion- All patients underwent complete electrophysiologic evaluation and successful radiofrequency catheter ablation- None ofthem had pre excitation in sinus rhythm- Results : There were 99 atrioventricular node reentrant tachycardias (AVNRT) and 116 AV reciprocating tachycardias (AVRT)- STsegment depression or T wave inversion > 1-5 m V on inferior lead was present more often in AVRTthan in AVNRT, and the sensitivity were 62-5 % vs- 6-7 % ,70-2 % vs- 16-3 % and 64-4 % vs- 6-7 % on lead Ⅱ, Ⅲand aVF,respectively- The mean magnitude of Tinversion of AVRTon lead Ⅱ, Ⅲand aVF1-7 ±0-8 m V,1-6 ±0-8 m Vand 1-5 ±0-8 m V- For AVRT,the specificity of STdepression/Twave inversion were 93 % ,90 % and 93 % on lead Ⅱ, Ⅲand aVF- The percentages of STsegment/T wave inversion on lead Ⅱ, Ⅲand aVFin AVRT with right side accessory pathway were significantly higherthan those with left side accessory pathway (84 % vs- 48 % ,86 % vs- 53 % and 82 % vs- 50 % ,respectively ,all p < 0-001)- Conclusion : The presence of STsegment depression/T wave inversion > 1-5 m V on inferior leads during narrow QRS complex tachycardia , strongly suggests arioventricular reciprocating tachycardia- This finding is helpful for the promptly distinguisgment of orthodromic AVRT using a concealed accessory pathway-
