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 Correlation between Infarct Size and the QRS Axis Change after Thrombolytic Therapy in ST Elevation Acute Myocardial Infarction.
OBJECTIVE Electrocardiography (ECG) may be a practical guiding tool for prognostic infarct sizing in ST elevation acute myocardial infarction (STEAMI). In this study, we sought to find a relation between the infarct size and the change in the QRS axis after thrombolytic therapy. MATERIALS AND METHODS Patients with STEAMI who received thrombolytic therapy were selected retrospectively. The mea...
متن کاملEnzymatic and Immunogenic Changes of Myocardial Infarction
Diagnosis of myocardial infarction is very important in a patient with chest pain. Chest pain is not always present or it may be from other causes rather than myocardial infarction. Q wave is present in 30] of infarction. ST,T wave changes are present in all myocardial infarctions, but these changes also are present in myocardial ischernia. For these reasons diagnosis of myocardial infarction...
متن کاملThe construction method of the QRS loop in myocardial infarction.
In order to investigate the relation between the infarcted area in myocardial infarction and the change of the QRS loop, the following method was tried. The normal QRS loops in 3 planes were constructed with the digital computer. Then the vector of an optional segment corresponding to infarction was diminished and the QRS loops were constructed. The comparison of the QRS loops in clinical cases...
متن کاملTransient QRS changes simulating acute myocardial infarction.
The purpose of this study was to determine the characteristics and incidence of abrupt occurrence of abnormal initial QRS forces that cannot be explained by acute myocardial infarction or left or right ventricular overload. Computerized data from 3175 patients with suspected acute infarction were reviewed to identify those in whom the ECGs revealed QRS complexes considered to be diagnostic (Q w...
