Abstract

In 16 patients with acute transmural myocardial infarction the effect of 8 mg of intravenous oxyfedrine followed by an infusion of 0.3 mg/kg body weight per hour on haemodynamics of the pulmonary and systemic circulation and dynamic cardiac indices was investigated. Cardiac rate, systemic arterial blood pressure, minute volume, cardiac output, and tension-time index remained unchanged on the whole. On the other hand oxyfedrine produced a persistant significant decrease of the mean and diastolic pulmonary artery pressure, pulmonary capillary pressure, and of the contraction and pressure-increase time. These effects were also demonstrable in patients previously treated with digitalis. No cardiac arrhythmias were observed. The positive inotropic effect of oxyfedrine is suggested as reason for these changes.

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.

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.
