Using the isolated perfused guinea-pig heart and a system for quantitating rhythm disturbances based on computer-aided statistical analysis of beat-to-beat intervals, a number of factors influencing the incidence of rhythm disturbances were investigated. Manipulation of perfusate composition revealed that, after 'moderate' ischaemia, reperfusion arrhythmias were increased in the presence of noradrenaline and non-glucose fuels. Free fatty acids, unless in the presence of catecholamines, were not particularly arrhythmogenic. In contrast, the presence of pyruvate or lactate, endproduct inhibitors of glycolysis, significantly increased incidence of reflow rhythm disturbances. The dose-dependent arrhythmogenic effects of pyruvate and anti-arrhythmogenic effects of glucose support the thesis that inadequate glycolytic flux could be important in the development of arrhythmias.</p>","PeriodicalId":72971,"journal":{"name":"European journal of cardiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18252073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All the patients of the CAD group were selected from 230 CAD patients because of their normal values in standard ejection phase indices (i.e. ejection fraction, EF; mean velocity of circumferential fiber shortening, VcfM; mean normalized systolic ejection rate, MNSER). An 'instantaneous' evaluation of the ventricular function, by means of a frame-by-frame analysis throughout the ejection period, allowed us to detect abnormalities of ventricular ejection in the early phase of systole in these CAD patients. In comparison with the control group, the CAD group presented similar peak values of dV/dt, dV/dt/EDV and Vcf, and a significantly longer time to peak values of these indices; EF curve analysis showed similar values at the end of systole in the two groups, but the mean curve of the CAD group was significantly lower in the first third of ejection when compared with that of control group. A segmental wall motion analysis in the early phase of systole showed a diffuse delayed ventricular wall motion (tardokinesis) related to abnormalities demonstrated by frame-by-frame analysis of ejection phase indices. Our results confirm that the CAD patients may have abnormalities of ventricular performance in the early phase of systole even when standard ejection phase indices are still within the normal range. In addition, the chronological appearance of these abnormalities during the whole systole has been clearly assessed; finally, these data confirm the importance of acceleration in blood ejection from the left ventricle as an index of ventricular function.</p>","PeriodicalId":72971,"journal":{"name":"European journal of cardiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1981-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18299572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
