Not accepted
You may be eligible if
Supraventricular tachycardia (SVT) compatible with atrioventricular nodal reentrant tachycardia (AVNRT), documented by ECG, TTM, Holter or event monitor
Subject must have one electrophysiology study documented inducible sustained (greater than or equal to 15 seconds) supraventricular tachycardia that is classified as AVNRT.
You may not be if
History of sustained (≥30 seconds) of ventricular tachycardia
Atrial tachycardia or other arrhythmia that could be confused with AVNRT
Reversible cause of SVT
History of previous AVNRT ablation
Therapy with amiodarone within last 90 days
Unstable angina/myocardial infarction/open heart surgery in past 60 days
New York Heart Association (NYHA) Classification III or IV currently or within the past 90 days
Implantable cardiac rhythm device
Atrioventricular block (first degree (PR interval ≥ 220ms), second degree, or third degree) or left bundle branch block
Stroke or transient ischemic attack within the past 180 days
Life expectancy less than 12 months
Female known to be pregnant
Unable/unwilling to give informed consent
Unable/unwilling to comply with follow-up visits and study requirements
Less than 18 years of age
Active systemic infection
Cryoglobulinemia
Other conditions where the manipulation of the catheter would be unsafe (for example, intracardiac mural thrombus)
Participating in a concurrent clinical study that may confound the results of this study
Presence of a second inducible arrhythmia that could be confused with AVNRT during follow-up or will likely result in ablation within the next 6 months
Presence of inducible sustained ventricular tachycardia or fibrillation
Presence of an accessory pathway
Presence of abnormal conduction or refractoriness parameters of the atrioventricular conduction system.
Indication for a pacemaker, defibrillator or cardiac resynchronization therapy (CRT)
