(vā'sō-pres'in, vas-ō-),

In pharmacologic doses vasopressin causes water retention and contraction of smooth muscle, notably that of all blood vessels; large doses may produce cerebral or coronary arterial spasm.

The following parameters were monitored before, during and after pitressin infusion (30 min): ST-segment elevation (height, mm) and duration (s); alteration of T-wave; duration (s) of the P-Q and Q-T intervals; and percentage incidence of the arrhythmias.
In all control guinea-pigs, intravenous administration of pitressin resulted in the typical electrocardiographic signs of coronary arterial spasm (ST-Segment elevation, increase voltage or inversion of the T-wave, prolongation of the P-Q and Q-T intervals), in an elevation of arterial blood pressure of 40.
5, 5 and 10 mg/kg) significantly decreased the electrocardiographic signs of coronaryspasm, the pressor response and the incidence of cardiac arrhythmias induced by pitressin.
