[The UHF therapy of hypertension patients].

Ninety-three patients with stages I-II essential hypertension treated with microwave electromagnetic fields (460 MHz) with collar exposure were studied. Microwave therapy was found to produce an antihypertensive effect in 74%, chiefly by lowering the increased cardiac output, to improve blood pressure responses to exercises, to make catecholamine excretion normal and coronary and cerebral circulation better.
