Objective To analyse the cause of abnormal Q wave ECG but with normal 201Tl myocardial imaging. Methods 69 patients both studied with ECG and 201Tl myocardial imaging. Results 60 of 69 cases, 87% have abnormal Q wave. 23 of 69 cases, 33.3%, include 9 intraventricular conductional block, 7 dilated cardiomyopathy, 5 hypertrophic cardiomyopathy, 2 aortic regurgitation. All patients have normal results in 201Tl myocardial imaging. Conclusions The diagnosis of old myocardial infarction by ECG must be well...

All patients have normal results in 201Tl myocardial imaging. Conclusions The diagnosis of old myocardial infarction by ECG must be well considered. However, radionuclide myocardial imaging should be the routine method for the diagnosis of old myocardial infarction.

目的 分析临床心电图 (ECG)出现异常Q波而核素心肌显像正常的原因。方法  6 9例患者分别行ECG和2 0 1 Tl心肌显像。其中男 5 2例 ,女 17例 ,4 5岁以下 2 8例。结果  2 5例ECG表现为前间壁心肌梗死 ,33例表现为下壁心肌梗死 ,5例表现为前间壁 +下壁心肌梗死 ,4例表现为侧壁心肌梗死 ,2例表现为正后壁心肌梗死 ;误诊为前间壁或下壁心肌梗死共 6 0例 ,占 87%。经心脏超声、ECG等检查 ,6 9例中 9例为心室内传导障碍 ,7例为扩张型心肌病 ,5例为肥厚型心肌病 ,2例为风湿性心脏病主动脉瓣关闭不全 ,共 2 3例 ,占 33 3% ,其余各种检查未见明显异常。结论 依靠ECG诊断陈旧性心肌梗死应慎重 ;核素心肌断层显像应为诊断心肌梗死的常规检查方法。

Objective Transmyocardial laser revascularization(TMLR)is a modern approach in the treatment of patients with chronic ischemic ca rdiac disease.The histological features of CO 2 laser created channels after transm yocardial laser therapy have not been described previously.The purpose of this experiment is to study the histologic characteristics of laser created channels after TMLR in animal models of acute ischemia.Methods Acute myocardial ischemia was created by multiple ligation of the coronary artery in 8dogs.The laser procedu re was performed on the animals by beating heart using high power CO 2 laser.Channels were created in the a rea of interest(3-5holes /cm 2 ).The animals were sacrificed at 7day,1month and 6months after TMLR,respectively.The laser -created channels in unfixed and formalin -fixed tissue were grossly located.The laser -tre ated areas were excised and cut lengthwise for histological investigati on with established staining method.In addition,some of tissue specimen s were observed with scanning electr onic microscopy.Results Immediately after application of th e laser,four concentric zones(vaporization,carbonization,fixation,and transition)could be distinguished along the transmyocardial path.Up to 6months,laser induced channels remained patent,and th e containing red blood cells were surrounded by solid tract of con nective tissue.Direct communications were observed between some of the channels and ventricular cavities.Conclusions The laser channels remained patency6months after TMLR.The laser patency channel features were related to la ser pulse width and intramyocardial pressure.

目的观察CO2激光对犬急性心肌缺血行心肌打孔后孔道的形态学变化,以探求TMLR的供血机制。方法8只杂种犬采用冠状动脉结扎方法造成左室前侧壁心肌梗死或缺血。使用大功率CO2激光在心肌缺血区域打孔,打孔数目3~5个/cm2,分别在TMLR后1周、1和6个月将犬心脏取出,经相应组织学方法处理后进行光镜和扫描电镜观察。结果孔道刚建立时可见气化孔道、炭化焦痂、坏死带及变形细胞层由内向外依次排列;TMLR后1周时孔道开放,孔道边缘有炎细胞浸润,1及6个月孔道内壁光滑,孔道与其它心肌结构相连,同时孔道周围的心肌微循环结构较前丰富。但孔道内壁的变化及炎症反应的程度与激光脉冲时间有关。结论TMLR后激光心肌孔道可以较长期保持通畅,使心腔内的氧合血通过这些孔道灌注心肌。但激光脉冲时间和心壁压力大小对孔道的通畅影响较大。

Objective To observe the relationship between electrocardiogram injury pattern in aVR and aVL and clinical prognosis in patients with acute anterior myocardial infarction.Methods One hundred and two cases with anterior myocardial infarction who received thrombolytic therapy were selected.Electrocardiogram at admission were analyzed.ST segment elevation or depression ≥0.05mV in aVR lead were defined as aVR injury pattern.aVL injury pattern included any of the following criteria (1)ST elevation≥0.05mV;(2)any symmetrical T-wave inversion associated with less degree ST elevation;(3)any isoelectric ST segment associated with both symmetrical T-wave inversion and an abnormal Q wave(≥30ms in duration).Echocardiography were examined at 2 weeks and LVEF were measured in all patients.All cardiac events in hospital were recorded.Results (1)Peak value of CK and CK-MB were higher in patients with aVR injury pattern than without.(2)Peak value of CK and CK-MB were higher and LVEF were lower in patients with aVL injury pattern than without.(3)Peak value of CK,CK-MB,left ventricular end systolic volume (ESV),the incidence of left ventricle aneurysm were higher and LVEF were lower in patients with aVR and aVL injury pattern than without.Conclusion ECG aVR and aVL injury pattern in patients with acute anterior myocardial infarction were the important marker in predicting clinical prognosis.

目的 探讨急性前壁心肌梗死患者心电图aVR和aVL导联损伤图形与临床预后的关系。方法 入选急性前壁 (包括前壁、广泛前壁、前壁 +侧壁 )心肌梗死患者 10 2例 ,分析入院当时心电图 ,aVR导联损伤图形指ST段抬高或压低≥0 0 5mV ;aVL导联损伤图形包括以下情况之一 :①ST段抬高≥ 0 0 5mV ;②ST段抬高幅度 <0 0 5mV同时伴有T波对称性倒置 ;③ST段在等电线而伴有T波对称性倒置和病理性Q波形成 (时间≥ 3 0ms)。所有患者于发病 2周行超声心动图并测量左室射血分数 (LVEF)。记录入院期间心脏事件情况。结果 ①伴aVR导联损伤图形者CK、CK MB峰值明显增高。②伴aVL导联损伤图形者CK、CK MB峰值明显增高而LVEF明显减低。③同时伴aVR和aVL导联损伤图形者CK、CK MB峰值、左室收缩末期容积 (ESV)和室壁瘤发生率明显增高 ,而LVEF明显减低。结论 急性前壁心肌梗死时aVR和aVL导联均表现损伤图形是判断预后不良的重要指标
