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。

The 4th left rib was cut and a model of left coronary artery occlusion/release was carried outo Rats were divided randomly into 4 groups: control group without LCA occlusion (group A, n=6);I/R group(group B, n=6); ketamine(5mg.kg-1)+I/R group (group C, n=6); ketamine(10mg.kg-1)+I/R group(group D,n=6)o All rats in groups B, C , D were subjected to 30 minutes of LCA occlusion followed by 120minutes of reperfusion. Rats in group C and D were injected with 5mg.kg-1 and 10mg.kg-1 of ketamine before reperfusion, respectively. Significant electrocardiogram and color changes at the area at risk were considered indicative of successful coronary occlusion and reperfusionc Serum was exampled from left jugular vein at 30 minutes and 120 minutes during reperfusion to measure IL-6 and TNF- level by ELISA measurements. After reperfusion of 120 minutes, the heart was removed and the cardiac apex was exampled with snap-frozen in liquid nitrogen and stored at -70 C .

采用左冠状动脉前降支结扎开放建立心肌缺血／再灌注模型，健康SD大鼠24只，随机分为心包打开假手术组(A组，n=6)，缺血／再灌注对照组(B组，n=6)，5 mg·kg~(-1)氯胺酮+缺血／再灌注组C组，n=6，缺血30min后右腹股静脉注入5 mg·kg~(-1氯胺酮，10mg·kg~(-1)KTM+I／R组D组，n=6，缺血30min后右腹股静脉注入10 mg·kg~(-1氯胺酮。10％水合氯醛40 mg·kg~(-1)腹腔注射麻醉，气管切开，连接多功能监护仪记录心电图；小动物呼吸机人工呼吸，呼吸频率60次／分，潮气量2ml／100g，于左胸第四肋间打开胸腔暴露心脏，在左心耳下1mm左冠状动脉处，用丝线，眼科外用不锈钢小圆针穿过心肌浅层，稳定10min后将U型含有铜丝的胶管置于冠状动脉表面一起结扎(A组不结扎，B、C、D组结扎)；结扎开始左心室心尖部即由红色变暗，30 min后呈暗红色，心电图中出现S-T段抬高，说明缺血形成。

"These findings support the current strategy of directing patients with suspected acute coronary syndrome to the nearest hospital with acute care facilities, irrespective of the availability of a catheterisation laboratory, and argue against early routine transfer of these patients to tertiary care hospitals with interventional facilities," the authors write."Our results do not suggest that an invasive approach to patients with acute coronary syndrome is harmful but that a more restrictive selective use of invasive procedures, as usually applied to patients first admitted to a community hospital, is at least as effective as a more liberal routine use."

研究人员表示，这些发现支持了目前将怀疑是急性冠状动脉疾病病患送到最近的、具有紧急照护设施医院的策略，不论该医院是否具有心导管设施，并且争议早期固定将这些病患转送到具有介入设施三级医院的作法；我们的结果暗示，对急性冠状动脉疾病患者进行侵入性的作法是有害的，但是侵入性手术的受限，就像将病患送到社区医院一样，与更不受限的作法比起来是同样有效的。

Arrhythmias included second degree atrioventricular block in 3 patients, paroxysmal ventricular tachycardia in 3 patients and frequent ventricular premature beat in 3 patients. Cardiac syncope occurred in 2 patients with Ⅱ°AVB and in a patient with VT.Significant coronary stenosis related to ischemia occurred in 5 patients, and coronary artery was normal in 1 patient.
