BSPM in the cranial zone of positive potentials, which occupy the largest section, were conducted on the ventral and dorsal sides of body surfaces, and BSPM in the caudal zone of negative potentials--on the dorsal side (Fig.
On BSPM of 27% of ISIAH rats before the beginning of the [P.
In the present study, an original source of electrocardiographic information were the ECG recordings collected in the 87-electrode BSPM system.
A subject of comparison were isopotential maps created in the BSPM system from the patients with right bundle branch blocks.
Measurement of VATs was semi-automatically performed in each patient by the Fukuda Denshi model 7100 BSPM equipment (Fukuda Denshi Co.
In the present study, the BSPM was employed to assess and analyze patients implanted with a cardiac resynchronization device as to their clinical evolution regarding the functional class presented before and after undergoing CRT.
2 years) with angiographically documented critical single-vessel (SVD) coronary artery disease among them 52 patients with left anterior descending artery (LAD) involvement, 40 patients with right coronary artery (RCA) and 18 patients with left circumflex artery (Cx) lesions, without any specific ischemic changes on standard resting 12-lead electrocardiogram (ECG), isointegral and departure ST-T maps were recorded using Fukuda Denshi (Tokyo, Japan) 87-electrode system for BSPM.
As it was widely documented, BSPM has a unique spatial resolution, and at the same time, it retains completely a time-signal relation typical for standard ECG.
Conclusions: Beat-to-beat dynamics of white noise components of high resolution BSPMs
are able to stratify arrhythmia vulnerability.
We consider that the electrocardiographic variables obtained with the use of the BSPM, namely, the QT and Tpeak-end intervals, are appropriate for analysis and study of the effects of cardiac resynchronization therapy on the improved electrical dispersion as characterizing the improvement of homogeneity of cardiac ventricular repolarization.
The BSPM study was performed with a model 7100 Fukuda-Denshi equipment (Fukuda-Denshi, Tokyo, Japan), with 87 electrodes, 58 placed on the anterior chest and 29 on the back.
Maps can be recorded with different lead system and various methods of analysis of BSPM
have been used to study repolarization potentials.
