A canine model of gastric electrical stimulation

Electrical stimulation or pacing of the stomach has been advocated as a possible treatment for gastric motor dysfunction. To date, researchers have employed frequencies similar to, or slightly higher than the native electrical control activity frequency in gastric stimulation with little success. In the present study, the efficacy of electrical stimulation at frequencies ranging from 3 to 30 cycles/min was investigated in a dog model. The study compared the relative efficiency of the "low-frequency" stimulating signal (3 to 9 cycles/min) versus the "high-frequency" signal (20 and 30 cycles/min) in generating contractions.
