1·The cause of death was concluded to be severe hypotension, bradycardia and cardiac failure due to combined intoxication with verapamil, metoprolol and digoxin.
死亡原因是维拉·帕米、美多心安和地高辛联合中毒引起的严重低血压、心动过缓和心脏衰竭。
2·Digoxin directly inhibits the sodium-potassium ATPase pump in the membrane of the cardiac myocyte, causing an increase in intracellular sodium and calcium which increases myocardial contractility.
地高辛直接抑制心肌细胞膜的钠-钾atp酶泵，导致细胞内的钠和钙的增加，进而增加心肌收缩力。
