Summary

Irradiation of various parts of the rabbit body by microwaves of λ=12.5 cm at an intensity below the thermal level (7–12 mw/cm2) influenced the sinus rhythm. This chronotropic effect of the microwaves was observed during the 20-minute period of irradiation, and for 10 minutes immediately after it. Irradiation of the ventral parts of the body slowed the heart, and irradiation of the dorsal part of the head speeded it. It is suggested that the effect observed was the result of reflex autonomic reactions provoked by the direct action of the microwaves on the superficial reflexogenous zones, and that the effect from irradiation of the head was produced by action on brain cells.
