Supraventricular tachycardia, pregnancy, and water: A new insight in lifesaving treatment of rhythm disorders

Pregnancy may predispose to paroxysmal supraventricular tachycardia (SVT), in sub- jects with or without identifiable heart disease. Many physiological conditions such as autonomic nervous system changes, altered systemic hemodynamics, etc. can contrib- ute to the onset of arrhythmias during pregnancy. Some cases reported the occur- rence of arrhythmias in relation to systemic fluid variations. We report the case of a pregnant woman who experienced SVT due to fluid depletion, detected by bioimped- ance vector analysis (BIVA), which was successfully treated by water repletion under tight BIVA monitoring. Emergency physicians can overcome dangerous drug adminis- tration by considering historical examination and using fast and reproducible tech- niques such as BIVA.
