| Popis: | 1. 1. Supernormal phase of A-V conduction was recorded for the first time under experimental conditions in an intact mammal (dog). Potassium was the agent responsible for depression of A-V conduction and appearance of supernormal conduction. 2. 2. This observation bridges the gap between the previously described supernormal phase in compressed and fatigued heart muscle preparation, on one hand, and in the human heart, on the other hand, and supports strongly the existence of supernormal phase of A-V conduction in the clinically reported cases. |
