Question | Answer |
---|---|
hypokalemia | Increased cardiac instability & risk for dig toxicity. *ventricular dysrhythmias, EKG changes |
Hyperkalemia | Asystole, ventricular dysrhythmias, ekg changes |
Hyponatremia | low levels from diuretic use, or low lvl in heart failure indicating water excess. Hypocalcemia. Ventricular dysrhythmias, ekg changes, cardiac arrest |
Hypocalcemia | ventricular dysrhythmias, cardiac arrest |
Hypercalcemia | EKG changes, AV block, tachy or brady cardia, digitalis hypersensitivity, cardiac arrest. |
P- phosphorus | should be interpreted with calcium levsl because the kidneys retain or excrete one electrolyte in an inverse relationship to the other. |
Hypomagnesaemia | Ventricular tachycardia & fibrillation, EKG changes |
BUN | Elevated in heart disorders that adversely affect renal circulation: Heart failure & cardiogenic shock |
Glucose | elevated with acute cardiac episode- physiologic stress |
