Radiofrequency Ablation of Paroxysmal Supraventricular Tachycardia Using a Novel Catheter Equipped...
Paroxysmal Supraventricular TachycardiaParoxysmal supraventricular tachycardia is treated with radiofrequency ablation recently. This procedure is performed by ablating slow pathway or accessory pathway using radiofrequency ablation catheter. Recently developed mirofidelity (MIFI) catheter has mini-electrodes that can record local eletrogram with higher resolution. We aimed to investigate the efficacy of MIFI catheter in the ablation of paroxysmal supraventricular tachycardia compared to conventional radiofrequency ablation catheter. Enrolled patients undergo conventional electrophysiologic study. Patients with sustained supraventricular tachycardia during the study are randomized to either study group or control group. Radiofrequency ablation is performed using MIFI catheter in the study group, and conventional catheter (Blazer II) in the control group. The study endpoints are recorded immediately after ablation and there is no additional follow up or management after procedure.
Study on Left Atrial Function of Paroxysmal Supraventricular Tachycardia After Radiofrequency Ablation...
Paroxysmal Supraventricular TachycardiaThis study to investigate the effects of RF ablation on left atrial systolic function in patients with atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular tachycardia (AVRT).
TOCCATA - Touch+™ for Catheter Ablation
Atrial FibrillationTachycardia1 moreThe main objective of this study is to demonstrate the clinical safety of a contact force sensing RF ablation catheter when used for the treatment of supraventricular tachycardia and atrial fibrillation. In addition, the study will characterize the use and value of contact force measurement during ablation, and the long term success (12 months) of the ablation procedure using this technology.
Effectiveness of Calcium Channel Blockers and Adenosine in the Emergency Management of SVT
Supraventricular TachycardiaThe purpose of this study is to determine the efficacy and effectiveness of calcium channel blockers and adenosine in the treatment of Supraventricular Tachycardia.
Oral Verapamil in Acute Paroxysmal Supra Ventricular Tachycardia(PSVT) Recurrence Control
Paroxysmal Supraventricular TachycardiaPSVT is a common rhythm disorder in emergency department which can be recurrent in some cases. Intravenous Adenosine is the drug of choice in PSVT control in acute settings but is a very short acting agent. Providing a complementary medication to decrease the rate of recurrence of PSVT after its initial control will be promising. This study evaluates the role of the oral Verapamil in recurrence control of PSVT in emergency situations.

Using Non-Fluoroscopic Imaging Devices to Decrease Radiation Exposure During Ablation of Supraventricular...
Supraventricular TachycardiaThe purpose of this study is to determine whether the additional use of non-fluoroscopic imaging modalities can decrease the use of radiation exposure during standard ablation procedures for supraventricular tachycardia (SVT) in children.
Dipole Density Mapping in Supraventricular Tachycardia
Supraventricular TachycardiaUse of dipole density mapping to identify activation in complex supraventricular tachycardias.
Reducing Episodes by Septal Pacing Efficacy Confirmation Trial (RESPECT)
Atrial FibrillationTachycardia3 moreThe purpose of this study is to find out if specialized programs in the AT500 and EnRhythm pacemakers will reduce the number of irregular heartbeat in the upper chamber of the heart and reduce symptoms (such as shortness of breath, dizziness, and others).
Simulation of Adenosine Push Methods for Treatment of SVT Using Agitated Saline Visualized by Ultrasound...
Supraventricular TachycardiaSupraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart. SVT is commonly treated with adenosine using three different IV administration techniques. However, it is not well known which of these three techniques is the quickest or most likely to reach the heart in order to stop SVT. This study will simulate each of those techniques in an investigator-blinded procedure. Intravenous agitated saline, used as a surrogate for a dose of adenosine, will be administered to healthy volunteers using all three techniques and monitored using bedside ultrasound to observe their efficacy and speed in reaching the right side of the heart.
