Fig. 3. A dysrhythmic and tachygastria episode of gastric slow waves during hyperglycemia. (A) Activation maps of the start, mid and post dysrhythmia are shown. The first and third (waves 1 and 3) cycles both demonstrate the normal direction of propagation (), whereas the second wave (wave 2) illustrates an episode of figure-of-8 re-entry. (B) The selected electrograms demonstrated that tachygastria (up to 12 cpm) was associated with the period of re-entry (up to 30 seconds), followed by a 63 seconds of quiescence, before recovery back to the normal direction of propagation, with the exception of the double potentials in some of the posterior channels (p4–p7).
