Use of dipole density mapping to identify activation in complex supraventricular tachycardias.
The primary objective of this study is to demonstrate the superiority of at least 1 dose of intranasal (IN) MSP-2017 (Etripamil) over placebo in terminating PSVT induced in an electrophysiology (EP) laboratory.
Stimulants and drugs are often associated with cardiac effects. Caffeine, a therapeutic xanthine, has been described as a sympathomimetic and has shown to have stimulatory effects on the heart. Patients with symptomatic cardiac arrhythmias are generally informed by their physician to stop or significantly reduce caffeine intake. However, in spite of numerous reports that have reviewed the cardiac effects of caffeine, it remains unclear to what extent this stimulant may be detrimental, and what subgroups of patients may be most vulnerable. The investigators propose to evaluate the effects of caffeine in patients with previously diagnosed cardiac arrhythmias. The results of our report will provide important new information for physicians and patients regarding the effects of caffeine on symptomatic cardiac arrhythmias.

PSVT 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.
Atrioventricular nodal reciprocating tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT) are two similar supraventricular re-entry tachycardias (SVT) emerging in relatively young age in patients without apparent structural heart disease or significant comorbidities. The treatment of choice in those patients is radiofrequency ablation (RFA). The PPRA study is a prospective observational study developed to thoroughly analyze quality of life, utility and willingness-to-pay of Polish patients undergoing RF ablation of AVNRT or AVRT. Based on collected data the investigators will prepare a profile of patient who will benefit most from radiofrequency ablation and who should be scheduled in first place for the ablation in case of problems with accessibility to this service. What is more an analysis of medical and indirect costs of care will be performed.
ICY-AVNRT (Intracardiac CrYoablation for AtrioVentricular Nodal Reentrant Tachycardia) is a prospective multi-center, nonrandomized, single arm, controlled, unblinded, investigational clinical study. The purpose of this clinical study is to demonstrate the safety and effectiveness of the Freezor® Xtra Cardiac CryoAblation Catheter for the cryoablation of the conducting tissues of the heart in the treatment of patients with atrioventricular nodal reentrant tachycardia (AVNRT) using an endocardial approach.
