Abstract:
We describe the case of a patient who developed torsade de pointes during temporary pacemaker insertion after administration of intravenous erythromycin. The case highlights the dangers of administering drugs that prolong the QT interval in patients with complete atrioventricular block, and we discuss the underlying pathophysiological recipe that can lead to a potential arrhythmic disaster.
Insights
Intravenous erythromycin can cause dangerous heart arrhythmias like torsade de pointes in patients with complete atrioventricular block. This case highlights the risks of QT-prolonging drugs in vulnerable cardiac patients.
Area of Science:
- Cardiology
- Clinical Pharmacology
Background:
- Complete atrioventricular block presents significant risks for cardiac arrhythmias.
- Certain medications can exacerbate these risks by prolonging the QT interval.
