METHOD FOR PREDICTING THE RISK FOR THE DEVELOPMENT OF PAROXYSMAL ATRIAL FIBRILLATION IN PATIENTS WITH ISCHEMIC CARDIAC DISEASE

FIELD: medicine, cardiology. ^ SUBSTANCE: one should register a standard electrocardiogram (ECG) and measure the duration of a "P"-wave. Moreover, it is necessary to conduct daily ECG monitoring to calculate single, paired and group atrial extrasystoles. Then one should calculate diagnostic coefficient DC by the following formula: DC=DC1+DC2+DC3+DC4, DC1 =-8.8 at duration of "P"-wave below 106 msec, 9.3 at duration of "P"-wave above 116 msec, -3.5 at duration of "P"-wave ranged 106-116 msec. DC2=-1.9 at the absence of group atrial extrasystoles during a day, 8.3 -at daily quantity of group atrial extrasystoles being above 4, 2.5 - at daily quantity of group atrial extrasystoles ranged 1-4. DC3=-2.9 at daily quantity of paired atrial extrasystoles being below 3, 8.1 - at daily quantity of paired extrasystoles being above 35, -1.4 - at daily quantity of paired atrial extrasystoles ranged 3-35. DC4=-5.1 at daily quantity of single atrial extrasystoles being below 15, 4.3 - at daily quantity of single atrial extrasystoles being above 150, -1.0 - at daily quantity of single atrial extrasystoles ranged 15-150, if DC is above or equal to 13 one should diagnose high risk for the development of paroxysmal atrial fibrillation, in case if DC is below or equal -13 it is possible to diagnose no risk for the development of paroxysmal atrial fibrillation, and if DC is above -13 and below 13 - the diagnosis is not established. ^ EFFECT: higher sensitivity of diagnostics. ^ 5 ex
