Hemodynamic effects of beta blockers

Abstract

Beta-blockers have been used in cardiology for the past 15 years in three directions: angina pectoris, cardiac arrhythmias, and hypertension. The haemodynamic effects are real: --imposed bradycardia, whether the basal rhythm be sinus or atrial fibrillation; --confirmed myocardial depression which reduces the energy needs of the myocardium; --fall in systolic pressure, the mechanism of which remains open to discussion. The theories explaining these haemodynamic effects are reviewed. The harmful effects of these substances are defined, together with the drug combinations which may avoid or counteract them.

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.

Atrial Filbrillation

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

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.
