Vectorcardiography in myocardial infarction.
Standard limb leads and unipolar electrocardiography can provide valuable information in the diagnosis of myocardial infarction but there are occasions when the cardiographic changes are inconclusive. It may be difficult to differentiate between pericarditis and myocardial infarction. The electrocardiographic changes in posterior or lateral infarction are not always characteristic. It is not al...
متن کاملThe history of vectorcardiography.
Vectorcardiography (VCG) is a part of electrocardiography (ECG). The vectorcardiogram displays the various complexes of the electrocardiogram, i.e. QRS, P and T complexes, in the form of "loops" which are determined from vectors representing successive instantaneous mean electric forces from the heart throughout an entire cardiac cycle. Since the heart is a three-dimensional structure, the elec...
متن کاملThe clinical value of vectorcardiography.
SOME WORKERS, with great enthusiasm about the clinical value of vectorcardio-grams, may, after reading this article, believe it should be classified under some heading other than Clinical Progress, but the writer hopes that the discussion will at least point out clearly the relationship between ordinary electrocardiograms and vectorcardiograms and some of the problems relating to the registrati...
متن کامل[Vectorcardiography in Wolff-Parkinson-White syndrome].
Twenty-six patients with Wolff-Parkinson-White (WPW) syndrome were studied by echocardiography. They were classified into the following WPW types: anterior right ventricular pre-excitation (Type I) - six patients; posterior right ventricular pre-excitation (Type II) - six patients; posterior left ventricular pre-excitation (Type III) - fourteen patients. Twenty-three patients were in WPW at the...
متن کاملVectorcardiography Based Analysis of Atrial Fibrillation
This paper discusses the feasibility and effectiveness of using vectors of the current dipoles representing local electric activity inside the atrial myocardium during atrial fibrillation. The application relates to the search for improving the performance of electric signals observed on the body surface in the diagnoses of this life-threatening arrhythmia. The topics addressed include some his...
