The diagnosis of W-P-W syndrome accompanied with acute myocardial infarction is very difficult, because the negative delta waves in W-P-W syndrome may be similar to the abnormal Q waves of acute myocardial infarction, and the positive delta waves may mask the characteristic electrocardiographic changes of AMI. Two cases are reported and references are reviewed. Here in this paper seven important points are suggested for the diagnosis of W-P-W syndrome accompanied with AMI.

预激综合征(W-P-W综合征)合并急性心肌梗塞(AMI)时,诊断比较困难。因其负性delta波可酷似急性心肌梗塞的心电图变化,而阳性delta波又可掩盖急性心肌梗塞的特征性心电图图形改变。我们遇到2例,结合文献复习,对WP-W综合征合并AMI提出了7个方面的诊断要点,可供临床参考。

The atrioventricular (AV) accessory pathway (AP) potential in 10 patients with Wolff-Parkinson-White syndrom was recorded with close-space catheter in coronary sinus or largetip radiofrequency ablation catheter directly in the left ventricule. The potentials were recorded in eight patients during sinus rhythm. The atrium-pathway interval (A-AP) was29.4±9.4ms, APdelta wave interval 10.0±6.5ms and AP-ventricle interval 20.7±0.90ms. The amplitude of the AP was 0.78±0.41mV, Five AP potentials was recorded during...

The atrioventricular (AV) accessory pathway (AP) potential in 10 patients with Wolff-Parkinson-White syndrom was recorded with close-space catheter in coronary sinus or largetip radiofrequency ablation catheter directly in the left ventricule. The potentials were recorded in eight patients during sinus rhythm. The atrium-pathway interval (A-AP) was29.4±9.4ms, APdelta wave interval 10.0±6.5ms and AP-ventricle interval 20.7±0.90ms. The amplitude of the AP was 0.78±0.41mV, Five AP potentials was recorded during AV reentrant tachycardia and the mean amplitude was 0.46±0.36mV. The ventricle-AP interval (V-AP) and AP-strium interval (AP-A) was 52.2±20.5ms and 34.0±23.0ms respectively. The sites of APs were determined by ablation catheter. All the pathways were blocked With radiofrequency ablation and AP potential disapeared in the same time. The results suggested that AP potential is an excellent marker for the location of accessory pathway and ablation.

以冠状窦内导管或大头消蚀导管记录10例预激综合征患者的房室旁道(AP)电位。8例前传AP电位均起源于同步ECG delta波前0~20ms,平均波幅为0.78 mV,A-AP间期多在30 ms以内,AP电位在V波前15 ms以上。4例逆传AP电位的平均波幅为0.46 mV,V-AP及AP-A分别为52 ms及34 ms。记录AP电位有助于房室旁道的准确定位及其传导特性的研究。

Three patients with Wolff-Parkinson-White syndrome and a delta wave pattern indicative of an overt left-sided free wall accessory pathways undewent radiofrequency ablation with the use of only one catheter. No patient had a previous electrophysiological study. The catheter was introduced into the left ventricule close to the mitral annulus and was used for mapping as well as for ablation. The approach was completely successful in all the patients after the procedure. Overall procedure duration was 1.3 hours,...

Three patients with Wolff-Parkinson-White syndrome and a delta wave pattern indicative of an overt left-sided free wall accessory pathways undewent radiofrequency ablation with the use of only one catheter. No patient had a previous electrophysiological study. The catheter was introduced into the left ventricule close to the mitral annulus and was used for mapping as well as for ablation. The approach was completely successful in all the patients after the procedure. Overall procedure duration was 1.3 hours, there were no acute complications. The tachycardia did not reccur after 2 months follow-up. Thus, the single-catheter approach is feasible, safe and effective for the patients with overt left-sided accessory pathways.
