79 Possible Causes for Hyperkalemia, Short QT Interval

  • Acidosis

    She responded to thiazide diuretics and her BP is well controlled, and acidosis and hyperkalemia are corrected.[] When this process is abnormal, it can cause too much potassium to build up in the blood ( hyperkalemia ). This can be a problem for the heart and other organs.[] Pseudohypoaldosteronism (PHA) type II is an extremely rare disorder which presents with hypertension, hyperkalemia, and normal anion gap metabolic acidosis.[]

  • Primary Hyperparathyroidism

    Read More CE/CME Hyperkalemia in Adults: Review of a Common Electrolyte Imbalance Author: Melanie Douglas, PA-C Denise Rizzolo, PhD, PA-C Danielle Kruger, PA-C, MS Ed Although[] QT interval on the electrocardiogram 20.[] Also, manifestations related to symptomatic hypercalcemia can be present; these include nausea, vomiting, constipation, polyuria, polydipsia, mental confusion, coma, and a short[]

  • Digitalis Toxicity

    Abstract Cardiac glycoside toxicity is frequently associated with hyperkalemia and dysrhythmias in patients with renal insufficiency.[] Her labs revealed digitalis toxicity and hyperkalemia. Actual lab values not available. With digitalis toxicity, hypokalemia and hyperkalemia are possible.[] Thirdly digoxin toxicity is associated with hyperkalemia (2,3).[]

  • Metabolic Acidosis

    She responded to thiazide diuretics and her BP is well controlled, and acidosis and hyperkalemia are corrected.[] Correction of hyperkalemia leads to correction of metabolic acidosis in many patients, pointing to the central role of hyperkalemia in the pathogenesis of this acidosis.[] Decreased responsiveness to catecholamines Pulmonary vasoconstricition Neurological consequences: Cerebral vasodilation, thus increased intracranial pressure Electrolyte changes Hyperkalemia[]

  • Respiratory Acidosis

    CNS; HA, drowsy, restless, tremor, cofusion, disorientation - COMA (cerebral vasodilation, increased bloodflow to brain) & death -increased HR, lack of energy, weakness -hyperkalemia[] In addition, acidemia causes an extracellular shift of potassium, but respiratory acidosis rarely causes clinically significant hyperkalemia.[] Sodium bicarbonate (NaHCO 3 ) May be given in small IV doses in emergency situations to quickly correct acidosis if pH is less than 7.25 and hyperkalemia coexists.[]

  • Cardiac Arrhythmia

    The probable cause of arrhythmia is succinylcholine-induced hyperkalemia.[] Idiopathic short QT interval: a new clinical syndrome? Cardiology. 2000; 94: 99–102 Brugada J, Brugada R, Brugada P.[] While there is little doubt about the threat of lethal arrhythmias due to hyperkalemia, convincing evidence for the danger of low potassium dialysate and rapid or excess potassium[]

  • Hyperkalemia

    In patients with diabetic nephropathy, hyperkalemia may be caused by the syndrome of hyporeninemic hypoaldosteronism.[] PR and QT intervals, sinus tachycardia, sinus bradycardia, idioventricular rhythm, 1st and 2nd degree heart block [3].[] We present a case of hyperkalemia, initially diagnosed as ventricular tachycardia, to demonstrate how difficult hyperkalemia can be to diagnose.[]

  • Familial Short QT Syndrome

    Acquired disease –the most common cause– results from electrolyte disturbances or drugs, in addition to hypercalcemia, hyperkalemia, and acidosis; SQT manifests with digoxin[] […] of CSQTS is an abnormally short QT interval.[] […] an increase in I Ks . 10 A distinctive electrocardiographic feature of the short QT syndrome is the appearance of tall peaked T waves, similar to those encountered with hyperkalemia[]

  • Addisonian Crisis

    Aldosterone is the first-line defense against hyperkalemia.[] An EKG may show peaked T waves from hyperkalemia or short QT interval from hypercalcemia [13] .[] In a patient who developed clinical signs of intracranial hypertension, bilateral papilledema and diplopia, in association with mild hypotension, hyponatremia and hyperkalemia[]

  • Ventricular Fibrillation

    A : Here is the AHA position on Sodium Bicarbonate: “In some special resuscitation situations, such as preexisting metabolic acidosis, hyperkalemia, or tricyclic antidepressant[] ECG : [ 1 ] evidence of MI, prolonged QT interval, short PR, WPW pattern or other conditions. CXR: signs of left heart failure, pulmonary hypertension.[] […] depending on the clinical context, associated diseases and evolution of treatment): magnesium sulfate, propranolol (or other beta blockers), sodium bicarbonate (to treat hyperkalemia[]
