It was described by French physician François Dessertenne in 1966. Prolongation of the QT interval can increase a person's risk of developing this abnormal heart rhythm, occurring in between 1%-10% of patients who receive QT prolonged in relation to the development of hypothermia (p<0.001). Hypokalemia was signiﬁcantly associated with the development of PVT (p=0.002), with this arrhythmia being most likely to develop in patients with serum potassium values of less than 2.5mmoll−1 (p=0.002). Rebound hyperkalemia Wilkes NJ, Mallett SV, Peachey T, Di Salvo C, Walesby R. Correction of ionized plasma magnesium during cardiopulmonary bypass reduces the risk of postoperative cardiac arrhythmia.

Arrhythmias, Cardiac/complications* to-moderate hypokalemia is harmful, it has been speculated that low serum potassium may trigger cardiac arrhythmias and sudden death. The initial observations associating hypokalemia with cardiac arrhythmias were made in digitalized patients.29 These observations were later confirmed,30 and there is consensus that hypokalemia may aggravate arrhythmia, pulse thread and weak, altered mental status increase dietary potassium, administer potassium, supplement (IV & PO) - potassium chloride, monitor I&O and serum [quizlet.com] In hypokalemia-induced arrhythmia, IV potassium chloride must be given more rapidly, usually through a central vein or using multiple peripheral veins simultaneously. Infusion of 40 mEq (40 mmol) potassium chloride /hour can be undertaken but only with continuous cardiac monitoring and hourly serum potassium determinations. Hypokalemia and hyperkalemia are common electrolyte disorders caused by changes in potassium intake, altered excretion, or transcellular shifts.

Better health. Different reasons of sudden death are postulated including serum potassium imbalance leading to arrhythmia [4,5]. To define the hypokalemia, the cut off value of serum potassium level is less than 3.5 mEq/L. In a study it was conducted in patients with hypertension, acute MI and heart failure, the frequency of hypokalemia was around 17% [6].

Hepatic enzyme inducers (eg, barbiturates, carbamazepine, phenytoin, rifampin) Dexamethasone plasma levels may be reduced, decreasing the efficacy. In addition, seizure control with phenytoin may be altered. Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Potassium helps carry electrical signals to cells in your body. It is critical to the proper functioning of nerve and muscles cells, particularly heart muscle cells.

Treatment The treatment of hyperkalemia involves protecting the heart against the onset of arrhythmias, and decreasing the level of potassium in the bloodstream. One of the medicines used to decrease hyperkalemia is sodium bicarbonate.

The initial observations associating hypokalemia with cardiac arrhythmias were made in digitalized patients.29 These observations were later confirmed,30 and there is consensus that hypokalemia may aggravate Potassium deficiency, also referred to as hypokalemia, occurs when the body does not contain enough potassium to properly carry out its functions. Your level of potassium usually falls between 3.6 and 4.8 mEq/L of blood.

Weakness and fatigue are often the first signs of … This arrhythmia can lead to sudden cardiac death. Treatment The treatment of hyperkalemia involves protecting the heart against the onset of arrhythmias, and decreasing the level of potassium in the bloodstream. One of the medicines used to decrease hyperkalemia is sodium bicarbonate.

The effects of potassium on the electrophysiologic properties of the heart have been extensively studied and clearly are arrhythmogenic. Hypokalemia increases resting membrane potential and increases both the duration of the action potential and the duration of the refractory period, the latter to a greater degree than the former. Hypokalemia is a frequent disorder, especially important in cardiac patients. While in patients without heart disease hypokalemia rarely leads to death, among cardiac patients (who have inherent risk for arrhythmias and who frequently use medications potentially augmenting the risks of hypokalemia and/or arrhythmia) unrecognized hypokalemia may be one of the leading causes of iatrogenic mortality.
