... inhibition Stopping the heart by stimulation of the vagus nerve in the neck causing rapid death. It may be caused in many ways including pressure on the neck and sudden immersion in cold water. There are no post mortem signs and the diagnosis can be made only by elimination of other factors and evidence surrounding the...

...carbazole 5-HT 3 (serotonin) antagonist used to prevent perioperative nausea and vomiting, and postoperative shivering . It is presented as a clear colourless solution for intravenous administration or in tablet form. Mechanism of action is by inhibition of the 5-HT 3 -mediated vomiting reflex via vagal afferents in the small intestine peripherally, and the area postrema in the medulla centrally. Side effects include flushing, constipation, headache, bradycardia, and, rarely, convulsions and anaphylaxis...

...also inhibition of activity in sympathetic nerves decreases both the rate and force of contraction of the heart and dilates of both the resistance and the capacitance vessels (veins) (Fig. 1). Fig. 1 The baroreceptor reflex. An increase in blood pressure increases the rate of nerve impulses from baroreceptorto brain. Vagal centres are stimulated: increased activity in the vagus nerve to the pacemaker slows the heart. Sympathetic centres are inhibited causing less activity in sympathetic nerves. As these nerves are excitatory, the effect of inhibition is to...

...surgery in the early 1950s. In the same period, a technique devised by Adolf Fick for calculating the output of the heart was used successfully for human diagnosis. The heart's specialized conduction system was thoroughly investigated by F. W. Stannius , who demonstrated vagal inhibition and the intrinsic pacemaker (how the heartbeat is regulated). In 1893 Wilhelm His discovered the auriculo-ventricular bundle of special conducting tissue that bears his name, often coupled with that of A. F. Stanley Kent , who discovered the bundle independently in the...
