Abstract

The article provides the results of thyrotropic hormones (TH) influence on spontaneous paroxysms of cardiac fibrillation (CFP), central hemodynamics, electrophysiology (EP) of the heart and effectiveness of antiarrhythmic drugs (AAD) in patients with coronary heart disease (CHD). It is shown that in CFP patients TH should be evaluated in sinus rhythm and in arrhythmia. Fluctuations in TH contribute to CFP. EP and hemodynamic effects of TH manifest with shorter effective refractory period of the left atrium and atrioventricular junction, disturbed diastolic function of the left ventricle. TH affect efficiency of AAD in CFP patients with CHD.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Anti-Arrhythmic Drug Therapies

Anti-arrhythmic drugs are used to prevent abnormal heart rhythms. These medications are used in conditions including, ventricular tachycardia, ventricular fibrillation and atrial fibrillation. Discover the latest research on anti-arrhythmic drug therapies here.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Antiarrhythmic Agents: Mechanisms of Action

Understanding the mechanism of action of antiarrhythmic agents is essential in developing new medications as treatment of cardiac arrhythmias is currently limited by the reduced availability of safe and effective drugs. Discover the latest research on Antiarrhythmic Agents: Mechanism of Action here.
