Repolarization alternans (RA) is characterized by its amplitude and instant of occurrence along the JT segment, but only the amplitude is generally used to discriminate abnormal cases. The role of RA timing was focused in the present study. ECGs from 201 coronary-artery-disease (CAD) patients and 167 control-healthy (CH) subjects were analyzed by our heart-rate adaptive match filter (AMF) method to...
The aim of the current study was to study the low-frequency power distribution of diastolic heart sounds in patients with coronary artery disease (CAD). Heart sound recordings were made from the 4th intercostal space in 132 patients referred for elective coronary angiography. CAD patients were defined as subjects with at least one stenosis with a diameter reduction of at least 50% as identified with...
Accurate identification of patients with acute coronary syndrome (ACS) is often difficult especially when an electrocardiogram (ECG) does not show typical changes of ST segment. The aim of the present study was therefore to investigate the sensitivity of magnetocardiography (MCG) and electrocardiogram for the early diagnosis of coronary artery disease in patient presenting with acute chest pain. Methods...
