METHOD FOR EVALUATING INTRA-ATRIAL AND INTER-ATRIAL STIMULATION PROCESS Russian patent published in 2006 - IPC A61B5/402 

FIELD: medicine, cardiology, arhythmology, functional diagnostics.

SUBSTANCE: one should register electrocardiogram in esophagus, apply an electrode in a site where the maximum signal amplitude is registered, increase the signal 5-fold, not less to be filtered in the range of 0.5-40 Hz to be registered at the rate of 100 mm/sec, not less. The time for intra-atrial process should be measured from the beginning of ascending part of the first positive wave of pre-P-tooth up to the top of the second adhesion of P-tooth; the time for inter-atrial process should be measured from the site of crossing a descending part of the first positive wave and the onset of obliquely ascending pre-P-interval up to crossing this interval with the point of abrupt increase of the first phase of P-tooth. The innovation provides more means for noninvasive evaluation of intra- and inter-atrial stimulation process.

EFFECT: higher accuracy of evaluation.
