The Actions of Lyophilized Apple Peel on the Electrical Activity and Organization of the Ventricular Syncytium of the Hearts of Diabetic Rats

Figure 9

Reentrant activity initiated by the application of an early extrasystole. The traces shown correspond to action potentials recorded in the papillary muscles of diabetic rats, in the area proximal (upper trace) and the area distal (lower trace) to the stimulation site, at a basic cycle of 500 milliseconds. Observe that, after the implementation of the extrasystole, two responses (asterisks) not evoked by stimulation appear, corresponding to a type of reentrant activity.
