Results: In all 13 patients, non-contact mapping showed AFLs confined to the RA with the cycle length (230 ±20 ms). 6 patients presented single-loop re-entry circulating around the central obstacle in the anterolateral wall through the channel between the CO and the crista terminalis .Seven patients presented "8" re-entry, and the gap of upper and lower loop located in CT in 4 cases, another 3 cases with upper loop and free-wall single-loop re-entry. RF of CT gap and/or the free-wall channel was effective in eliminating these AFLs in 13 patients.

结果 经 NMS标测证实13例患者折返均在右房内，激动在右房内的折返平均时间为230±20ms.6例房扑患者为单折返环，围绕右房中心障碍区折返，激动在心房的前壁穿过中心障碍区与界瘠之间的狭窄通道。7例患者证实为2个折返环，其中4例表现为上下折返环形成"8"字形折返，共同的传导通道在界瘠；另外3例表现为折返环1个在心房上部，1个在前游离壁。13例消融界瘠或前游离壁后房扑终止。

Vester等［6］对伴有VT的冠心病患者进行心房起搏(150 ppm)，胃痛发现在起搏期间出现了VLP；PTCA之后，VT不再发作，也不能诱发，再行心房起搏VLP阴性。

Situs solitus and situs inersus totalis were identified in 46.0% and 47.7% of patients, respectiely, and 6.3%(21 patients) had heterotaxy.

心房正常位和心房反位各占了在46.0%和47.7%， 6.3%(21名患者)有心脏旋转不良。

TEE was inserted and showed paradoxical gas embolisms in four chambers of the heart with interatrial septum bulging to the left side. No evidence of intracardiac right-to-left shunt was discovered.

经食道超音波检查证实产生paradoxical气体栓塞，心脏四个腔室都有许多气体存在，右心房鼓大合并心房中隔向左边膨胀，并无心脏右向左分流存在。

Objective To study the characters of L type calcium current of atrial isthmus,and to investigate the mechanism of arrhythmias related to atrial isthmus.

目的 研究心房峡部L型钙电流的特性，探讨心房峡部参与心律失常的机制。

Some electrophysiological index were measured, including atrial effective refractory period, rate adaptability, dispersion of AERP, inducibility and duration of induced atrial fibrillation under different basic pacing cycle length (300, 250 and 200 ms). Results: Contrast with control group, the values of AERP at 6 sites were shortened and maladaptation.
