喀喇

方法：①选择2005-06某部驻西喀喇昆仑山海拔3700m地区健康男性青年20名，平均年龄（20±1）岁。

METHODS : ① Totally 20 healthy young males stayed at high altitude of 3 700 m and mean age of ( 20 ± 1 ) years were selected from western Karakorum mountain area in June 2005 . All cases were told the fact .

3例心底部有收缩早期喀喇音。

Three cases had systolic early click murmur .

收缩期喀喇音82例分析

Analysis of 82 Cases With Systolic Click

可在二尖瓣脱垂（通常伴有收缩中期喀喇音）或主动脉瓣缩缝时听到。

They may be heard in mitral valve prolapse ( frequently accompanied by midsystolic clicks ) or coarctation of the aorta .

本文报告经心音图证实的收缩期喀喇音82例，经超声心动图证实绝大多数（82%）伴有二尖瓣脱垂。

The paper reported 82 cases with systolic click prored by phonocardiogram ( PCG ), most of them associated with mitral prolapse proved by echocardiogram .

于胸骨左缘可闻频速、高调清脆的喀喇样的附加心音，第三四肋间隙最清晰。

Rapid , high - pitched , clicking additional sounds were heard along the left sternal border , loudest in the third or fourth left intercostal space .

又走了几秒钟，他听到喀喇喇一声响，他觉得空气似乎又变了，变得芳香扑鼻。

After going on for a few seconds more he heard a crackling , and it seemed to him as though the atmosphere again changed , and became balmy and perfumed .

所以以前还没有电子收音机的时候，如果调那种老式收音机，电台里面有时候有“喀喇喀喇”的声音，那个就是杂音。

So the old days before digital radio when you were tuning in your radio and you heard " crrcckkk " on the station you wanted to hear , that was the noise .

方法：实验于2005-06选择进驻西喀喇昆仑山海拔3700m20d的某部健康青年士兵12名，均自愿参加本实验。

METHODS : Twenty young healthy soldiers who had been stayed in Karakorum Mountain , the altitude of which was 3 700 m for 20 days from 2005 to 2006 were selected , all participants took part in the experiment voluntarily .

同样听诊器有利于检查者发现二尖瓣脱垂时收缩中期喀喇音和心包摩擦音。结果收缩期脱垂的二尖瓣表面粗糙并向左房膨出，可伴有腱索异常。

Likewise , the stethoscope allows the examiner to detect mid systolic clicks in mitral valve prolapse and pericardial friction rubs . Results The surfaces of the prolapsed mitral valves showed rough and accompanied with abnormal tendinous chordae , and their bodies projected into left atrium during systole .
