Correlation between divalent cation concentration and electrocardiogram in canine myocardial infarction.


Myocardial infarction is accompanied by changes in serum divalent cation concentrations. The effects of these changes on the electrical activity of the heart have not been fully determined. In six mongrel dogs, major coronary arteries were catheterized and occluded with metal beads; in five dogs the arteries were catheterized, but left patent. Serum… (More)
