IN recent years there has been increasing interest in the clinical application of spatial vectorcardiography. Some comparative studies have indicated that the vectorcardiogram may be significantly superior to the conventional scalar electrocardiogram in the diagnosis of myocardial infarction and ventricular hypertrophy." 2 The Frank lead system3 has many theoretical advantages over the older ve...
Vectorcardiography (VCG) as an alternative form of 12-lead ECG is another method measuring the electrical activity heart. The use vectorcardiography in clinical practice not common, but VCG leads can be derived from ECG. has proven to a useful and more accurate tool for diagnosing various heart diseases within automated detection. This paper presents application four transformation methods name...
Until the mid-1980s, it was believed that the vectorcardiogram presented a greater specificity, sensitivity and accuracy in comparison to the conventional electrocardiogram, in the diagnosis of the different heart diseases. Recent studies revealed that the vectorcardiogram still is superior to the electrocardiogram in very specific situations, such as in the evaluation of electrically inactive ...
Reperfusion therapy has lowered the mortality in patients suffering acute myocardial infarction. Failure to reperfuse is associated with significantly higher risk of short- and long-term mortality. Detection of reperfusion is thus important. In a prospective pilot study, we used continuous on-line computerized vectorcardiography to monitor 21 patients with acute myocardial infarction treated wi...
