| Abstract: | - 1.1. Elevation of the concentration of potassium in the coronary sinus occurred only in 33 per cent of 69 dogs after ligation of a major coronary artery.
- 2.2. Eighteen of the 23 dogs (78 per cent) with an elevation of the level of potassium in the coronary sinus blood maintained a normal sinus rhythm throughout the experimental period.
- 3.3. Of 12 animals which developed ventricular fibrillation after coronary artery ligation, only 3 showed a significant elevation of the concentration of potassium in the coronary sinus. The other 9 failed to show any increase in the level of potassium in the coronary sinus. None of the 12 showed an increase in the concentration of potassium in the femoral artery.
- 4.4. These results fail to support the thesis that an increase in the levels of serum potassium incites ventricular fibrillation after coronary artery ligation.
