Background: Detection of myocardial ischemia was studied with multichannel exercise magneto-cardiography (MCG). A surface gradient method was applied to analyze cardiac magnetic fields. Methods: We studied 27 patients with single vessel coronary arte

Exercise induced ischemia was detected using a novel method for calculating the orientation of magnetic field at ST-segment and T-wave. Magnetocardiographic mapping was performed during supine physical exercise testing in 35 subjects including 23 pat

Body surface potential mapping (BSPM) data obtained during endocardial stimulation at multiple ventricular pacing sites show a broad spectrum of potential distributions. In this study, BSPM sequences are analysed using a neural network approach based

This study was performed to evaluate the accuracy of multichannel magnetocardiographic (MCG) and body surface potential mapping (BSPM) in localizing three-dimensionally the tip of an amagnetic catheter for electrophysiology without fluoroscopy. An am

The purpose of the study was to validate, in patients, the accuracy of magnetocardiography (MCG) for three-dimensional localization of an amagnetic catheter (AC) for multiple monophasic action potential (MAP) with a spatial resolution of 4 mm2. The A

The position of a non-magnetic pacing catheter was localized non-invasively from multichannel magnetocardiographic (MCG) measurements in 5 patients. A catheter specially designed to produce no magnetic disturbances was inserted in the heart after sta

High-resolution magnetocardiographic mapping was applied to localize the ventricular preexcitation site in ten patients suffering form Wolff-Parkinson-White syndrome. Three different source models were tested, consisting of the dipole and quadrupole
