Why the study?
Inappropriate sinus tachycardia presents diagnostic and therapeutic challenges due to an unclear etiology and limited treatment options.
Does continuous stellate ganglion block (CSGB) improve symptoms and reduce heart rate in patients with refractory inappropriate sinus tachycardia?
Does continuous stellate ganglion block (CSGB) improve symptoms and reduce heart rate in patients with refractory inappropriate sinus tachycardia?
Continuous stellate ganglion block may offer a promising therapeutic approach for prolonged symptom control and heart rate reduction in refractory inappropriate sinus tachycardia.
Inappropriate sinus tachycardia (IST) presents challenges in diagnosis and treatment due to its unclear etiology and limited therapeutic options. This case report explores the use of continuous stellate ganglion block (CSGB) as a potential treatment avenue. A 23-year-old woman with refractory IST underwent several CSGB placements, resulting in prolonged symptom relief and decreased median heart rate. Despite the eventual recurrence of symptoms, the sustained effects of CSGB suggest its efficacy in managing IST. This report underscores the potential of CSGB as a promising therapeutic approach for IST, offering longer-lasting symptom control compared to single-injection stellate ganglion block (SGB) interventions.
