| Popis: | 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. |
