Methods: Changes in QRST integral maps after nitroglycerine sublingual application were examined and single dipole best representing the difference QRST integral map was inversely computed.

Difference QRST integral maps (DI maps) as a difference between reference QRST integral map of record 0 and QRST integral maps of each record after nitroglycerine application were computed.

To confirm health condition of considered healthy subjects, their QRST integral maps were compared with available template (obtained from 72 healthy people measured in 32 leads according to Lux (4)) and departure QRST integral maps representing deviations from QRST integral map template were computed.

AQAL offers a comprehensive lens to both examine and meaningfully connect the complex and integral nature of human functioning; it is thought that this

integral map can support a rich exploration of sex-related issues, and more specifically the study, exploration, and promotion of healthy masculinity.

It is interesting, for example, to follow the

integral map of a formative, or the spread of loans borrowed into the Finnic languages in different periods (see Laanest 1995).

Features of the new ECU include drive-by-wire speed control, a proactive closed loop air/fuel control, an

integral map sensor for load compensation, engine temperature compensation and complete engine diagnostics.

In the group of arrhythmia patients, QRST integral map variability amplitudes increased significantly compared to the healthy group, while the random character of the pattern changes persisted.

Similarly, in normal subjects the autocorrelation functions of the KL components revealed a respiration dependent integral map pattern modulation.

Beat-to-beat QRST integral maps, Karhunen-Loeve coefficient time-series ([KL.sub.i], i=1-12), RR and nondipolarity index (NDI) time-series were computed.

In order to detect the susceptibility to ventricular arrhythmias, maps were recorded with different lead systems by different authors and, in particular, various methods of analysis of BSPM have been used to study repolarization potentials: QRST integral maps, eigenvector analysis, principal component analysis, autocorrelation analysis.

Eigenvector analysis (2) was proposed as a method to detect and quantify the non-dipolar components not evident on visual inspection of the integral maps. The cumulative contribution of the eigenvectors beyond the 3rd to an individual map, expressed as percentage contribution of the total map content, has been considered a "non-dipolar content" of that map.

Because the nondipolar content did not perform well in their study population, the authors examined how individual eigenvector pattern contributes to QRST integral maps in each group of patients.
