Cardiac arrhythmias due to potassium depletionMotte, G
Potassium ChannelsArrhythmiaPersonal failureComprehension钾通道心律失常hERG potassium channels are essential for normal electrical activity in the heart. Inherited mutations in the HERG gene cause long QT syndrome, a disorder that predisposes individuals to life-threatening arrhythmias. Arrhythmia can also be...
Serum potassium levels,cardiac arrhythmias,and mortality following non-ST-elevation myocardial infarction or unstable angina:insight from MERLIN-TIMI36. PATEL R B,TANNENBAM S,VIANA-TEJEDOR A,et al. Eur Heart J Acute Cardiovasc Care . 2017
Five series of experiments have been performed to investigate a possible causal relationship between the induced hyperkalemia and epinephrin-induced ventricular arrhythmias in pentobarbital anesthetized dogs. It is concluded that no causal relationship exists on the basis of the following observations. The ...
Mechanism of potassium channel block and its role in suppressing and aggravating cardiac arrhythmias. Although work on class III antiarrhythmics remains at an early stage, these agents still appear to possess greater efficacy and less proarrhythmia than con... TJ Colatsky,CH Follmer,CF Starmer -...
Thus, both hypokalemia (low plasma K + concentration) and hyperkalemia (high-plasma K + concentration) can result in potentially fatal muscle paralysis and cardiac arrhythmias, in part by altering conduction in skeletal and cardiac muscle. These functions are achieved by maintaining high intracellular...
alterations in membrane potential and cellular metabolism. They include fatigue, muscleweaknessand cramps and intestinal paralysis which may lead to bloating, constipation and abdominal pain. Severe hypokalemia may result in muscular paralysis or abnormal heart rhythms (cardiac arrhythmias) that can be ...
Cardiac arrhythmias (sinus bradycardia, sinus arrest, slow idioventricular rhythms, ventricular tachycardia, ventricular fibrillation, and asystole) Do not take potassium supplements without talking to your doctor, especially if you havekidney disease,diabetes,heart disease,Addison's disease,stomachulcers, ...

A significant inter-relationship between the plasma concentrations of magnesium and potassium and the evidence for a critical role of magnesium in the genesis of cardiac arrhythmias would support the proposal that magnesium should be routinely measured in situations, such as diuretic therapy, that are ...
