title: [The chronotropic reaction and the dynamics of the blood supply to the forearm during modulation of the baroreceptor reflex activity in patients with arterial hypertension].
abstract: Original method of baroreflex activation and deactivation was described. Bradycardia and vasodilatation of the forearm vessels were observed at baroreflex activation. Tachycardia and forearm blood flow reduction were observed at baroreflex deactivation. The sensitivity of baroreflex heart component vas shown to depend upon the arterial pressure and a baseline cardiac cycle duration in both normo- and hypertensive subjects.
