AIM To study the effect of canine the third fat pad ( SVC-AO FP FP) on effective refractory period ( ERP) of left atrium and left superior pulmonary vein and its effect on ERP dispersion of left atrium. 目的研究犬心脏第3脂肪垫(SVC-AOFP)对左心房及左上肺静脉有效不应期(PERP)及心房有效不应期(AERP)离散度的影响。
Methods Twelve female goats were instrumented with epicardial electrodes patches on the left atrium ( LA) and left superior pulmonary vein ( LSPV). 方法在12只山羊的左房游离壁及左上肺静脉外膜缝合电极片,心房快速刺激,诱发维持时间超过24h的持续性房颤。
In 14 dogs, the right superior pulmonary vein ( RSPV) was exposed via a right thoractomy; 探讨心脏脂肪垫在肺静脉灶性放电与心房颤动(简称房颤)中的作用。14条狗麻醉后经右侧开胸暴露右侧肺静脉。
The circuit of reentry located in the post wall of left atrium in 2 cases, related to left superior pulmonary vein in 3 cases, related to right superior pulmonary vein in 2 cases, and accompanied with typical atrial flutter in 1 case. 折返限于左房壁2例、与左上肺静脉有关3例、与右上肺静脉有关2例、合并典型心房扑动1例。
Results 206 pulmonary veins ( PVs) and 11 superior vena cava ( SVC) were isolated in 69 patients and one focal ablation of right superior pulmonary vein ( LSPV) was performed. 结果69例共电隔离肺静脉206根,上腔静脉11根,右上肺静脉口外点消融1例。
Method: a specially designed hook was introduced into the left atrium from the left superior pulmonary vein, partial chordae tendines of mitral valve were transected to produce moderate mitral regurgitation. 方法:经实验犬左上肺静脉置入特制金属钩,钩断部分二尖瓣腱索,产生中度二尖瓣返流。
Of 3 died cases were caused by mistaken ligation of right superior pulmonary vein during the operation. 11例手术中死亡3例,2例与右肺静脉连接变异有关。
Electrophysiological features and radiofrequency catheter ablation of atrial tachycardia originated from right superior pulmonary vein 起源于右上肺静脉房性心动过速的电生理特点及射频导管消融术
Effect of canine anterior fat pad on electrophysiological characteristics of left atrium and left superior pulmonary vein 犬心脏第3脂肪垫对左心房及左上肺静脉电生理特性的影响
On the sections of 27 cadavers ( 61.4%), left pulmonary artery and anterior segmental artery which together like a fishhook drew left superior pulmonary vein. 在27例(61.4%)断层标本上,左肺动脉与前段动脉一起呈鱼钩状勾绕左上肺静脉。
One of the two Afi cases triggered by left atrial ectopic beats given linear lesion between left superior pulmonary vein ( LSPV) and right superior pulmonary vein ( RSPV) during sinus rhythm; 2例左房心房颤动患者,1例在窦性心律下其致心房颤动房性期前收缩起源于左右上肺静脉之间,行线性消融成功;
