Summary: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.
