Objective: Study goal was a comparative analysis of the characteristics of the isopotential maps, registered originally in the body surface potential mapping (BSPM) 87-lead (complete) cylindrical system, which were then transformed to the 30-lead (limited) spherical subsystem.
As an example of the comparison performed between the body surface heart potential mapping obtained in the complete system and the limited lead system, the isopotential maps of the QRS complex recorded in the same patient with right bundle branch blocks are displayed in the Figure 2 and Figure 3, respectively.
In the both compared systems, the sequences of the isopotential maps representing the QRS complex were characteristic for conduction disturbances ongoing within the right bundle branch.
A subject of comparison were isopotential maps created in the BSPM system from the patients with right bundle branch blocks.
Isopotential maps make possible to monitor precisely successive phenomena taking place during depolarization and repolarization of the cardiomyocytes, but, on the other hand, these maps contain such data abundance that sometimes it is difficult to perform any quick interpretation, especially in clinical conditions.
