Abstract

In fasting and anaesthetic rabbits, the experimental model of gastric dysrhythmia could be produced by electric stimulation of inferior phrenicus vagus and splanchnic nerve for innervation of corpus and antrum, or by left gastric artery infusion of Adr, Ach and glucagon at a steady velocity. The results were as follows: (1) Electrical stimulation of inferior phrenicus vagus at low frequency and intensity could increase the frequency and amplitude of basic electric rhythmia (BER) or slow wave (P less than 0.01), and might induced tachygastria and tachyarrhythmia. Electrical stimulation of splanchnic nerve could increase the frequency and amplitude of BER (P less than 0.05), and might induced bradygastria. (2) Bradygastria could be elicited by left gastric artery infusion of Adr (400 micrograms/kg/h). The frequency and amplitude of BER induced were decreased. Tachyarrhythmia could be elicited by infusion of Ach (400 micrograms/kg/h). The frequency and amplitude of BER induced were increased. Dysrhythmia of BER could be elicited by infusion of glucagon (400 micrograms/kg/h). (3) Electroacupuncture of "Zusanli" acupoint may exhibit double modulated effects on experimental model of gastric dysrhythmia. Different types of gastric dys...Continue Reading

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
