You diagnose him with congestive heart failure. You consider various medications for his treatment, which aim to improve his cardiac function by slowing the rate and increasing contractility. Digoxin is one such drug (though it does appear to have a 20% higher all-cause mortality rate in atrial fibrillation patients, so it is not given without careful consideration). How does digoxin work in terms of altering movement of Na+, K+ and Ca++ and how does that relate to the improvement in cardiac function (increased contractility and slower heart rate)?
