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 induced by a blockage of hERG channels by a surprisingly ...
Cardiac arrhythmia (irregular heart rhythm). This requires immediate medical attention. What are the signs and symptoms of hyperkalemia? High levels of potassium (hyperkalemia) can produce the following signs and symptoms: Muscle weakness Fatigue Tingling Numbness Shortness of breath Irregular heartbeat...
Low potassium can cause a number of symptoms that should not be ignored as it can lead to more serious conditions, like arrhythmia and high blood pressure.
urinary systems, but may also have more far-reaching effects on human health. For example, prolonged potassium deficiency may lead to abnormal heart conduction, arrhythmia and even life-threatening conditions, especially in the elderly population. Potassium supplements (Potassium Orotate, Potassium Ascorba...
High plasma concentrations exert their most important effect on the heart, because arrhythmia and heart block are produced at plasma potassium concentrations of 8 to 10 mEq. per liter.1 A flaccid paralysis of skeletal muscle has been observed at high concentrations in some patients with advanced ...

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 - 《Circulation》 被引量: 417发表: 1990年 Blockade of Human Cardiac Potassium Channel Human Ether-a...
Low potassium is a known driver of cardiac arrhythmias, andTTFD possesses anti-arrhythmic propertiesand has historically been used to treat various types of arrhythmia in Japan. Furthermore,thiamine TTFD was also been shown to be protective against the cardiac toxin Strophanthin-G, preventing the...
Abnormal heart rhythms (arrhythmia ), especially if you're older Nausea, vomiting, or abdominal bloating Lightheadedness from low blood pressure If levels are severely low, your muscle tissue might start to break down (rhabdomyolysis). You might have paralysis and even respiratory failure. If you...
When potassium intakes exceed the amount that can be removed, the rising plasma concentration can cause muscle weakness, interference with electric conductance in the heart (arrhythmia), and eventually death due to cardiac arrest. The risk of hyperkalemia is particularly high in patients with renal ...
