METHOD FOR DETERMINING THE NORMAL AND PATHOLOGICAL REACTION OF THE CORRECTD QTc INTERVAL DURING EXERCISE TESTING Russian patent published in 2021 - IPC A61B5/00 

FIELD: cardiology/functional diagnostics.

SUBSTANCE: invention relates to medicine, namely to cardiology, to functional diagnostic. Measurement of QT interval is carried out, QTc is calculated according to A. Sagie's formula. Based on the data obtained, a regression line is plotted on the graph according to the formula QTc = a(RR)+b, where a is the slope coefficient, b is the shift coefficient (intercept), and the dependence of the QTc duration on the RR interval is estimated. When the QTc interval is "shortened" in response to a decrease in the RR interval (a> -0.079), the QT response is considered normal. When the QTc interval is “lengthened” (a -0.079), the reaction is considered pathological.

EFFECT: method improves accuracy of detecting the latent syndrome of the shortened QT interval or the latent syndrome of the extended QT interval in patients with normal or borderline QTc values ​​on the resting electrocardiogram.
