Key result
Among 15 pregnant patients with supraventricular tachycardia, sinus rhythm was successfully restored using vagus nerve stimulation (5 patients), esophageal pacing (4 patients), or medications (2 patients), while 3 reverted spontaneously.
Why the study?
Pregnancy increases the risk of SVT due to physiological changes, prompting a review of SVT management among pregnant patients in the emergency department.
What are the effective management strategies for supraventricular tachycardia in pregnant patients presenting to the emergency department?
Observational (n=15)

What are the effective management strategies for supraventricular tachycardia in pregnant patients presenting to the emergency department?
Vagal nerve stimulation and esophageal pacing are effective initial management strategies for stable pregnant patients presenting with SVT in the emergency department.
Supports non-pharmacologic reversion in stable pregnant SVT; hypothesis-generating pending controlled studies.
Background: Pregnancy increases the risk of supraventricular tachycardia (SVT) due to physiological changes. This study reviews the management of SVT in pregnant patients in the emergency department (ED). Methods: We retrospectively analyzed 15 pregnant patients with SVT treated at Shenzhen Second People's Hospital ED from 2015 to 2023. Treatments included vagal nerve stimulation, pharmacotherapy, esophageal pacing, cardioversion, and radiofrequency ablation. Results: The average patient age was 30.3 years. All presented with palpitations, and none had hemodynamic instability. Treatment success varied: 3 patients reverted spontaneously, 5 responded to vagal stimulation, and 4 to esophageal pacing. One required verapamil, and another responded to labetalol after failing vagal and pacing treatments. Conclusion: When managing SVT during pregnancy, it is important to consider the patient's stability, the stage of pregnancy, and the safety of medications. For unstable patients, electrical cardioversion is the preferred option; for stable patients, vagus nerve stimulation (VNS) or other alternative treatments, such as adenosine, should be considered.

Pan et al. (2024) conducted an observational in Supraventricular tachycardia (SVT) in pregnancy (n=15). SVT management (vagal nerve stimulation, esophageal pacing, pharmacotherapy) was evaluated on Restoration of sinus rhythm. Among 15 pregnant patients with supraventricular tachycardia, sinus rhythm was successfully restored using vagus nerve stimulation (5 patients), esophageal pacing (4 patients), or medications (2 patients), while 3 reverted spontaneously.
