The case of a 25-year-old woman presenting with chest pain, ECG changes, and laboratory Findings suggestive of myocardial infarction is reported. Cardiac catheterization showed impaired left ventricular performance but otherwise normal coronary arteries. Laboratory analyses revealed primary hypoparathyroidism...
Objective The aim of this study is to investigate the charateristic changes of ECG and myocardial enzyme during peri-operation of CABG. Methods CABG were performed on 41 patients who have narrowing in three coronary arteries.Time after time we detected myocardial enzyme by monitoring cardiogram and...
How does the ECG vary and what is occurring during these conditions: junctional rhythm, second-degree heart block, and ventricular fibrillation? ECG: The ECG variation can be represented by the reduced or increased amplitude of T-waves...

We observed the changes of high frequency electrocardiogram (HFECG) in 126 cases of coronary artery disease (CAD), On whom angiography was also performed. The results showed that the numbers of high frequency notches (HFN) in group MI and group AP were significantly higher than that in normal...
The aortic valve between the left ventricle and the aorta Each valve has a set of "flaps" (also called leaflets or cusps). The mitral valve normally has two flaps; the others have three. Image 3: Coronary Arteries Our heart supplies or pushes oxygenated blood to the cells throughout the ...
Coronary artery disease (CAD) is an irreversible and fatal disease. It necessitates timely and precise diagnosis to slow CAD progression. Electrocardiogram (ECG) and phonocardiogram (PCG), conveying abundant disease-related information, are prevalent cli
Repeated ECGs, blood tests, and monitoring may be necessary if the health care provider remains concerned about narrowing of the coronary arteries. There are situations where the ECG will show evidence consistent with an acute myocardial infarction, but the changes in the tracing are due to ...
The procedure is known as coronary artery bypass graft (CABG). The doctor will take blood vessel from another part of the body and graft them onto the heart to bypass one, two, three, or more blocked coronary arteries. The procedure requires a stay in the hospital afterwards to recover. ...
Prior studies examined association between short-term mortality and certain changes in the admission ECG in acute myocardial infarction (AMI). Nevertheless, little is known about possible differences between patients with diabetes and without diabetes in
