During astable anesthetic state, the calculated sinoatrial conductiontime and corrected sinus node recovery time were measuredbefore and after fentanyl administration.

在平稳的麻醉过程中，给予芬太尼（2.0ug/kg 静脉注射，继以0.075ug/kg/min 持续输注）并在给药前后测量窦房传导时间和校正窦房结恢复时间。

Create the model with sick sinus syndrome by external application of 20% methanal on the sino-atrial node. Observe the changes of heart rate and electro-physiological index of sinoatrial node.

In an attempt to determine non-invasively the sino-atrial conduction time, we recorded the sinus node electric activity by placing bipolar electrodes at the level of the right atrium anteroposteriorly across the chest of the dog.

本实验采用成年狗，以6极心导管电极从颈外静脉插至上腔静脉与右心房交界处，能记录到一个在心电图P波以前19—26毫秒的&P前波&。通过夹除窦房结和高血钾等实验证明，&P前波&可与P波分离而存在，并随窦房结夹除而消失。

The average SNERP of SSS patients was 525± 53.02ms,much higher than those of both the bradycardiac and normal cases (P0.01).The prolongation of SNERP(〉520ms)with high susceptibility and idiocrasy showed great significance for clinical diagnoses of sick sinus syndrome.

病窦组者SNERP平均值为525±53.02ms，显著高于窦缓组（427±18.19ms）和正常组（367.14±18.37ms）者（P〈0.01）；SNERP的延长（〉520ms）在病窦的诊断中具有重要的临床意义，其敏感性与特异性远较窦房结恢复时间与窦房传导时间为高。

Ⅱ型糖尿病大鼠窦房结16周后出现间质胶原重构，胶原类型比例失衡；Ⅱ型糖尿病大鼠行胰岛素降低血糖后可不同程度下调窦房结间质的沉积，一定程度上逆转胶原类型比例紊乱。

Results During isoprenaline administration the heart rate of arrhythmia in6cases went faster gradually and They were diagnosed as chronic sustained junctional tachycardia（3cases）and chronic atrial tachycardia（2cases）and sinoatrial reentrant tachycardia（1case）respectively;while the arrhythmias in other9cases disappered and turned to sinus tachycardiac and several minites after isoprenaline administration the arrhythmia in5cases recurred again,As a reˉsult,they were diagnosed non-paroxysmal ventricular（3cases）and non-paroxysmal junctional tachycardia（6cases）respectively.

结果 6例患者心动过速的频率逐渐增快，分别诊断为慢性持续性交界性心动过速（3例）、慢性房性心动过速（2例）和窦房结折返性心动过速（1例）；另9例异位心律失常消失，转变为窦性心动过速，停止滴注后数分钟5例再次出现原心律失常，诊断为非阵发性室性心动过速（3例）和非阵发性交界性心动过速（6例）。

Results The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with patients with normal frontal sinuses, the vertical diameters of agger nasi cells of patients with frontal sinusitis were larger(11.70±5.50 mm and 8.54±3.67 mm respectivevy, p＜0.01).Compared with patients with normal maxillary sinuses, the Haller's cells of patients with maxillary sinusitis were larger (77.8% and 33.3%,P＜0.05)and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6±17.8 mm2 and 41.6±12.6 mm2, respectively, P＜0.05). The deviation of uncinate process was one of the factors of maxillary sinusitis .The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause anterior ehmoid sinusitis.

结果 全中甲或中甲下部气化的发生率随前筛、上颌窦内软组织影增厚而升高；有额窦炎组病人的鼻丘气房最大纵向垂径明显大于无额窦炎组(分别为11.7±5.5 mm和8.5±3.7 mm，P＜0.01)；Haller气房在上颌窦炎组和非上颌窦炎组的发生率无显著差异，但前组发生炎症的Haller气房明显多于后组(分别为77.8%和33.3%，P＜0.05)，且前组Haller气房的冠状位截面积明显大于后组(分别为91.6±17.8 mm2和41.6±12.6 mm2，P＜0.05)；钩突角度随上颌窦内软组织增厚而减小；筛泡冠状位截面积随前筛窦内软组织增厚而增大(P＜0.01)。

The P wave duration and P 2R interval were increased while pacing at right atrial appendage 1 The activation time from pacing site to His bundle and coronary sinus was the longest in pacing at right atrial appendage , while the activation time in pacing at Koch triangle , Koch triangle with high right atrium and biatria was significantly shorter especially pacing at Koch triangle and Koch triangle with high right atrium1 There were no significant differences in right atrium pressure among all pacings1 Conclusion It is suggested that Koch triangle pacing could probably replace high right atrial with coronary sinus pacing and biatrial pacing 1

从心房激动顺序分析，右心耳起搏时，激动传至希氏束区及冠状窦区的时间最长，而 Koch三角、Koch三角+高位右房及双房起搏时则较短，尤其是 Koch三角、Koch三角+高位右房起搏缩短更明显。另外，不同部位、不同方式起搏时右心房压力无差异。结论 Koch三角起搏在某种程度上可替代高位右房+冠状窦起搏及双房起搏。

ObjectiveThe sinus node artery is the only blood supply for the sinus node, and cardiac arrhythmia is common when the artery is involved in coronary artery diseases or in heart surgeries. Thus its important for selective coronary angiographies and cardiac surgeries to make clear the form and course of the sinus node artery.

目的 窦房结动脉(sinus node artery，SNA)是窦房结的唯一血供来源，当冠心病或心脏手术累及该动脉时都可导致窦房结缺血而发生各种心律失常，所以对窦房结动脉的形态及走行的认识在选择性冠脉造影和心脏外科手术等方面都具有重要意义。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
