FIELD: medicine.
SUBSTANCE: presented is using 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine hydrobromide as an agent changing the total spectrum power of the heart rate variability and possessing anti-bradycardia properties. The effect of the invention can be used if it is necessary to increase the heart rate if it has dipped down, which can constitute an immediate risk of loss of the individual's life caused by a high risk of cardiac arrest emergency.
EFFECT: reducing the power of a high-frequency component of the cardiac rhythm spectrum by several times, reducing a RR interval variability factor by reducing the regulatory effect of the parasympathetic nervous system on the cardiac rhythm.
