Stellate Ganglion Block for Ventricular Tachycardia
This study is looking at how a treatment called a left-sided percutaneous stellate ganglion block affects the heart's electrical activity in people with ventricular tachycardia (a fast, abnormal heart rhythm). The stellate ganglion block involves injecting a drug near nerves in your neck. Researchers want to see if this block changes the Ventricular Effective Refractory Period (how long it takes for your heart's lower chambers to be ready for another beat) 30 minutes after the block. You may be able to join if you are at least 18 years old and are already scheduled for a catheter-based VT ablation (a procedure to correct the abnormal heart rhythm). You cannot join if you are pregnant, have certain medical conditions, or are allergic to the local anesthetic used. The current recruitment status is unclear, and the study plans to enroll 20 participants.
- Study design
- This is an interventional study, meaning participants will receive a specific treatment. It is a prospective cohort study, which means researchers will follow a group of participants over time.
- What's involved
- Not specified in the trial record.
- Compensation
- Not stated in the trial record.
- Follow-up
- The primary endpoint is measured 30 minutes after the stellate ganglion block.
