1. Effects of some non-steroidal anti-inflammatory drugs on ouabain-induced arrhythmias in guinea-pigs were studied. 2. Ventricular premature beats, ventricular fibrillation and cardiac arrest were induced in pentobarbitone-anaesthetized guinea-pigs by a slow intravenous infusion of ouabain. 3. Aspirin and indomethacin were found to accord a significant protection to the guinea-pigs against arrhythmias whereas ketoprofen was found to be ineffective. 4. It is concluded that the protective effect of aspirin and indomethacin may be due to inhibition of synthesis and release of thromboxane A2 from the myocardium.

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 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.
