Tachycardia, Atrioventricular Nodal Reentry | AV Nodal Reentrant Tachycardia Study

Tachycardia, Atrioventricular Nodal Reentry research study

What is the primary objective of this study?

The purpose of this study is to determine/identify what mechanisms/factors are involved with regard to AV nodal reentrant tachycardia.

Who is eligible to participate?

Inclusion Criteria: - Ages 16-80 - At least one documented episode of AV nodal reentrant tachycardia - Patient scheduled for electrophysiology study and catheter ablation for supraventricular tachycardia Exclusion Criteria: - Ages < 16 or > 80 - Medical condition significantly increasing risk of extending procedure time or X-ray exposure - Pregnancy - Prior ablation with radiation exposure >2 hours - Electrophysiology study performed without sedation or anesthesia - Unavailable for follow-up

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Tachycardia, Atrioventricular Nodal Reentry

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Procedure:Cardiac Invasive Electrophysiological StudyMapping and localizing of the components of the reentrant circuit as part of the Electrophysiological Study

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
