Preliminary observations of the effect of short time experimental ventricular tachycardia on glucose and insulin levels in pigs. A preliminarry communication

The aim of the research was to determine whether short-time heart muscle ischemia caused by fast ventricular pacing rate (ventricular tachycardia) provokes insulin and glucose blood level alterations and if so, how long those changes last after return to the physiological heart rate and restoration of proper heart muscle perfusion as well. It was stated that short-lasting tachycardia provoked by fast, forced ventricle rate, with no damage on the cardiac muscle resulted in significant fall of the glucose and insulin blood levels. The glucose returned to its initial level several minutes after heart rate normalisation; however, the insulin drop maintained for more than 10 min.
