目的:用门控核素心室显像法(门控核素法)及声学定量技术(AQ法)、M超法测定18例正常人及22例冠心病的左心功能参数,探讨三种方法测定左心功能的价值。方法:运用门控核素法及AQ法在较短时间内分别测定正常组和冠心病组的左室射血分数(LVEF)、左室最大射血率(LPER)、左室最大充盈率(LPFR)及左室最大充盈时间(LTPER),同时M超法测定LVEF作为心功能指标,并进行统计学分析。结果:门控核素法与AQ法病例组LVEF之间、LPER之间测值相关性均较好(r分别为065,058),且配对t检验均p>005;其余各组两种方法左心功能的测值之间相关性较差。正常组的LPFR之间及病例组的LPFR之间配对t检验p<005。M超法与门控核素法的正常组LVEF之间和病例组LVEF之间测值均很接近,各自配对t检验均p>005。结论:AQ法与门控核素法比较,其左心功能测值差异性较大。M超法测定LVEF是基本稳定和可靠的
OBJECTIVE: To determine the left ventricular function parameters of 18 normal subjects and 22 patients with coronary heart disease by M-gated by gated radionuclide imaging (gated radionuclide) and acoustic quantification (AQ) Determine the value of left ventricular function. Methods: Gated left ventricular ejection fraction (LVEF), left ventricular ejection fraction (LPER) and left ventricular maximum rate of filling (LVEF) were measured by gated nuclear nuclide method and AQ method in a short time. LPFR) and maximum left ventricular filling time (LTPER). At the same time, LVEF was determined by M-ultrasonography as a cardiac function index, and statistical analysis was performed. Results: There was a good correlation between gonadal radionuclide test and LVEF and LPER in patients with AQ (r = 065,058, respectively), and p> 005 by paired t test. The rest of the two groups of methods left ventricular function measured between the poor correlation. Paired t-test between LPFR of normal group and LPFR of case group p <005. M-method and gated nuclide method between normal group LVEF and case group LVEF measured values ?? are close to each paired t test were p> 0 05. Conclusion: AQ method and gated radionuclide method, the left ventricular function measured differences. The M-mode determination of LVEF is basically stable and reliable
