The production of ventricular arrhythmias following ligation of the right coronary artery in dogs.
Right ventricular infarction and associated ventricular arrhythmias. once considered rare. are now commonly recognised in patients with inferior wall infarction and clinical data is strongly suggestive of that cardiovascular changes occuring with human myocardial infarction vary importantly depending upon the site of myocardial infarction. Sympathetic hyper-activity is associated with the anter...
متن کاملThe origin of ventricular arrhythmias 24 hours following experimental anterior septal coronary artery occlusion.
The anterior septal coronary artery was acutely ligated in 16 open-chest anesthetized dogs to produce an infarct of the septal myocardium. Twenty-four hours following occlusion complete epicardial mapping and extensive plunge electrode recording techniques were used to localize the sites of origin and patterns of activation of the ventricular tachyarrhythmias that developed during recovery. The...
متن کاملEffects of carbon monoxide inhalation on myocardial infarct size following experimental coronary artery ligation.
This study was conducted to determine whether or not a low concentration of carboxyhemoglobin influences the extent and severity of myocardial ischemia caused by coronary ligation. In 10 dogs, electrograms were recorded from 6 epicardial electrodes mounted on the anterior surface of the left ventricle and distributed over the area normally perfused by the lighted branch of the left anterior des...
متن کاملAnti-coagulation therapy following coronary endarterectomy in patient with coronary artery bypass graft
Background: Since there is a lack of research on postoperative anticoagulation protocol in patients undergoing coronary artery bypass graft (CABG) / coronary endarterectomy (CE), we recommend a new protocol for anticoagulation in these patients. Methods: In this double-blind randomized clinical trial study, 52 patients undergoing CABG / CE entered the study and were divided into two groups. In...
متن کاملMyocardial Infarction Following Coronary Ligation in Dogs
In the subacute phase of myocardial infarction following coronary ligation in dogs, a relationship was noted between the extent of infarction and the degree of elevation of left ventricular end-diastolic pressure. Left ventricular filling pressure was consistently increased when 25% or more of the left ventricle was infarcted. Isoproterenol infusion resulted in enhanced left ventricular functio...
