Two cases of congestive heart failure with coexistent magnesium and potassium depletion are described. The prolonged QTc intervals and ventricular premature beats of the first patient and the idionodal tachycardia of the second patient disappeared only after magnesium repletion, which normalized both extra- and intracellular potassium and magnesium levels. The third patient had a case of urosepsis while on total parenteral nutrition. He developed diarrhea, hypocalcemia, hypokalemia, hypomagnesemia, weakness, muscular fasciculations and athetoid movements. The neurological manifestations were relieved and the biochemical abnormalities normalized only after magnesium repletion.
本文描述了两例伴有镁和钾缺乏的充血性心力衰竭病例。首例患者的QTc间期延长和室性早搏以及第二例患者的结性心动过速仅在补充镁后消失，补充镁使细胞内外钾和镁水平恢复正常。第三例患者在接受全胃肠外营养时发生了泌尿道感染。他出现了腹泻、低钙血症、低钾血症、低镁血症、虚弱、肌肉震颤和手足徐动症。仅在补充镁后，神经学表现得到缓解，生化异常恢复正常。
