The extremity and circumferential chest lead electrocardiogram in induced acute coronary insufficiency.

چکیده
The extremity and circumferential chest lead electrocardiogram (twenty-two leads) was studied in 8 patients with generalized coronary insufficiency induced by exercise. Over the right chest, posteriorly and laterally, there was noted RS-T elevation similar to but less pronounced than that occurring in lead aVR. These leads plrobably represent true or mixed cavity potentials. Standard leads revealed more marked RS-T alterations after exercise than did aV leads. In the left anterior chest leads, the greatest RS-T depression occurred in the left unipolar precordial leads representing the maximal voltage of the R weave usually V4 or V5. The practical application of these findings is discussed in relation to routine two step exercise tests.

Background :In addition to diagnosing the acute myocardial infarction (MI), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting MI. Many studies have been conducted to predict the occlusion site by interpreting the ST segment deviations in Electrocardiogram (ECG).Additional posterior and right precor...

Background: Slow coronary flow (SCF) is defined as a condition in which in spite of no evidence of coronary occlusion or stenosis in angiography, there is delayed pacification of the vessels after the injection of a contrast agent. There are several studies about electrocardiogram (ECG) changes in these patients, but changes like OLD MI, RBBB, LBBB, LVH and ST-T wave have not b...
