Electrocardiographic and hemodynamic changes in coronary angiospasm.

Electrocardiographic and Hemodynamic Changes

To investigate the electrocardiographic and hemodynamic changes in isolated right ventricular infarction, 0.25 ml or 0.5 ml of metallic mercury was injected into the right coronary artery of 14 closedchest dogs. At autopsy, at least 60% of the right ventricle was necrotic in every dog. Heniodynamic observations were made in 11 and electrocardiographic mapping was performed in all 14 dogs. Right...

Hemodynamic changes and related factors in patients undergoing coronary artery ‎bypass grafting surgery

Introduction: Coronary artery diseases are the primary and most common cause of death in all ages. ‎Coronary artery bypass grafting (CABG) surgery as a common treatment intervention is considered ‎necessary in patients with coronary artery disease. Complications may occur during and after ‎‎(CABG) surgery. Among major complications are hemodynamic changes after surgery which is ...

Role of coronary collateral vessels during transient coronary occlusion during angioplasty assessed by hemodynamic, electrocardiographic and metabolic changes.

The clinical role of collateral vessels was evaluated during transient coronary occlusion by percutaneous transluminal coronary angioplasty in 22 patients with (8) and without (14) collateral vessels. Coronary occlusion pressure, the ratio of mean coronary occlusion pressure to mean aortic pressure and myocardial perfusion pressure at 40 s of balloon inflation were significantly higher in patie...

Electrocardiographic changes during selective coronary angiography.

Electrocardiographic Changes During Selective Coronary Cineangiography

S ELECTIVE coronary angiography is being used with increasing frequency for clinical diagnosis in several forms of heart disease. Except for the works of Ross,' Hale and Jefferson,2 and Lehman and associates,3 there have been no detailed reports in the literature about the electrocardiographic changes accompanying the injection of radiopaque media selectively into the coronary arteries of man. ...
