A set of electrocardiographic criteria for the diagnosis of coronary artery disease was evaluated in two different groups of patients examined by computer aided 12 lead exercise electrocardiographic stress testing and coronary arteriography. One group consisted of patients with severe angina pectoris and the other of patients who had suffered a myocardial infarction three years before the study...

BACKGROUND Non-specific electrocardiographic ST-T wave changes and voltage criteria for left ventricular hypertrophy (LVH) have been associated with cardiovascular morbidity and mortality. The aim of the cohort study was to evaluate the prognostic value of non-specific ST-T changes and LVH electrocardiographic criteria on cardiovascular events and mortality in hypertensive patients. METHODS A...

Left ventricular hypertrophy is a risk factor for cardiovascular mortality, including sudden cardiac death. Experimentally, left ventricular hypertrophy delays ventricular conduction and prolongs action potential duration. Electrocardiographic QRS duration and QT interval measures reflect these changes, but whether these measures can further stratify risk in patients with electrocardiographic l...

• The electrocardiographic effects of electrical activity in the heart are partially canceled by multidirectional spread of that activity. For example, the effect of excitation directed toward the right may be canceled by a similar process moving toward the left. The extent of such cancellation is of fundamental importance in electrocardiography. It is a measure of the extent to which cardiac e...

A prospective cardiologic evaluation was performed in 83 consecutive patients with transient cerebral ischemia or mild stroke and without symptoms or electrocardiographic signs of ischemic heart disease. Patients were studied with an electrocardiographic exercise test; a positive test was followed by exercise Thallium-201 myocardial scintigraphy. Results were compared to those obtained in a gro...

DOI: 10.21276/sjams.2017.5.9.47 Abstract: OP compound poisoning is a global problem and is most common medicotoxic emergency in India. Cardiac manifestations are also seen due to OP poisoning which may be serious and often fatal if not diagnosed early and treated adequately. We studied clinical and electrocardiographic changes in op poisoning. To study the clinical as well as electrocardiograph...
