We wished to assess the effects of beta-blockade on baroreflex sensitivity and standard tests
of integrity of autonomic nervous function in patients with coronary artery disease, and to …

Based on solid experimental evidence the concept has emerged that analysis of autonomic
reflexes, and specifically of baroreceptive reflexes, might contribute to the identification of …

To determine whether β-adrenoceptor blockade lowers blood pressure by potentiating
arterial baroreflex sensitivity (BRS), we compared the effect of acute iv and chronic oral beta …

This study evaluated the effect of β blockade on cardiac autonomic control and its
dependence on heart rate change. The relations between RR interval duration, heart rate …

1. Baroreflex sensitivity is a useful tool for investigating cardiovascular reflexes in a number
of clinical settings. Several different methods of measuring baroreflex sensitivity are …

The overshoot rise in arterial pressure after release of Valsalva strain is a natural challenge
for baroreflex regulation of heart rate. To assess the feasibility of the Valsalva manoeuvre in …

To evaluate the effect of a hydrophilic and a lipophilic β‐blocker on the autonomic nervous
system, 20 normal subjects were studied under baseline conditions and 7 days after being …

Arterial baroreceptors play an important role among the large number of physiological
mechanisms governing the adjustment of cardiovascular system to several surrounding …

Decreased sensitivity of cardiopulmonary and arterial baroreceptors has been hypothe
sized to sustain sympathetic activation in patients with heart failure. In the present inves …

The purpose of the present study was to assess the agreement between measurements of
baroreflex sensitivity (BRS) obtained by the Valsalva manoeuvre and by the phenylephrine …
