Cardiac function is not impaired, in the absence of arrhythmias, and contractility seems enhanced since potassium depletion produces a significant increase in the mean systolic ejection rate, a rise in LV dp dt, and a higher LVSW and a trend to increased LVMW at similar levels of LVEDP. ...
Structure and function of cardiac potassium channels Recent advances in molecular biology have had a major impact on our understanding of the biophysical and molecular properties of ion channels. This review ... DJ Snyders - 《Cardiovascular Research》 被引量: 386发表: 1999年 Blockade of Human Ca...
Hyperkalemia can cause fatigue, muscle pains, irregular heartbeat, and in severe cases cardiac arrest and death. What is the range for normal potassium levels? Normal potassium levels should range between 3.7 and 5.2 mmol/L. These values can be detected via a blood test to find potassium ...
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...

目的 探讨门冬氨酸钾镁联合胺碘酮对慢性心力衰竭并室性心律失常患者心功能的影响。方法 选择232例慢性心力衰竭并室性心律失常患者,用随机数字法分为观察组和对照组,每组116例。对照组采用胺碘酮治疗,观察组在胺碘酮基础上加用门冬氨酸钾镁。治疗前后,检测两组患者的血压、心率、P-R与Q-T间期、左室舒张末期内径(LVD...
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 ...
On the other hand, current research in pharmacology has identified several reversible activators of hERG1 channels, which have the ability to improve cardiac function in LQT2 animal models.16–22 Among these, the best characterized hERG1 agonist is the diphenylurea derivative NS1643.19,23 At ...
Indeed, epilepsies and cardiac dysfunction are just two examples of many illnesses stemming from mutations in ion channels. These are collectively referred to as channelopathies. For example, mutations in heart Na+ and K+ channels can lead to a cardiac channelopathy called Long QT syndrome (...
