Hypoglycaemic syncope in children secondary to beta-blockers

Abstract

It has been reported that young children taking beta-blockers may be at risk of hypoglycaemia when fasting. However, hypoglycaemia is not listed as a side effect of beta-blockers in the British National Formulary for Children. We present five patients (out of approximately 570 patients at our institution who were prescribed regular beta-blockers over the same time period) who had severe hypoglycaemic episodes whilst taking beta-blockers for prevention of arrhythmia. We demonstrate how such an episode may be misinterpreted as an arrhythmic event and how this could lead to inappropriate escalation of medical therapy or even implantation of an automatic implantable cardiac defibrillator.

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.

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.
