Active clinical trials for "Tachycardia, Supraventricular"

This prospective study was conducted in 268 patients aged from 65-70 years posted for coronary artery bypass grafting. Patients were randomly allocated to either adenosine or verapamil(control) groups. In the adenosine group, patients received IV adenosine 6 mg bolus then wait 2 minutes, if it failed to return to sinus rhythm then another 12 mg IV bolus of adenosine was administered, if supraventricular tachycardia persisted then the patient was shifted to verapamil. In verapamil group, patients received IV verapamil 5mg bolus slowly over 2 minutes followed by a second IV bolus dose of 5 mg ,10 minutes after the initial dose in case of persistence of supraventricular tachycardia (SVT). If SVT persisted, the patient was shifted to adenosine. The efficacy of the study drug, ICU stay length, systolic blood pressure, hospital- stay length, duration of extubation, the total dose of the study drug used, the total cost of the study drugs and the incidence of adverse events were recorded.

Supraventricular tachycardia ablations of the Conformité Européenne (CE)-certified (since 2013) CartoUnivuTM module (Biosense Webster, Diamond Bar, USA) allows a seamless combination of a fluoro image and Carto® 3 System maps into a single view. This helps to reduce fluoroscopy levels and reduce exposure time for physicians, staff and patients to as low as reasonably achievable. The UnivuTM technology will be compared in a randomized manner to the conventional radiofrequency Ablation.

The goal of APART is the assessment of the therapeutic and preventive stimulation algorithms of the Medtronic AT500 and following devices in patients with atrial tachyarrhythmias and an indication for cardiac pacing according to the German guidelines. Medication is controlled throughout the study with a beta-blocker as the only antiarrhythmic drug.

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.

The purpose of this study was to explore the safety and efficacy of a Pulsed Field Ablation Device and Force Sensing Pulsed Field Ablation Catheter in the treatment of Paroxysmal Supraventricular Tachycardia.

NODE-303 is a multi-center, open label (OL) study to evaluate the safety of etripamil NS in patients with Paroxysmal Supraventricular Tachycardia (PSVT). Patients will be provided with an ambulatory Cardiac Monitoring System (CMS) to help document PSVT episodes. The CMS will be self-applied by the patient, when they feel the onset of PSVT symptoms. Patients will self-administer etripamil NS if vagal maneuver is ineffective. After an episode of PSVT where drug is administered, the patient will return to the investigative site and have the option to continue in NODE-303 and manage subsequent episodes of PSVT with etripamil NS.

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.

This is a randomized, double-blind, multi-centered study to compare 6 months of medical treatment with digoxin or propranolol in infants with SVT Background: SVT is the most common sustained arrhythmia of infancy. Neither digoxin nor propranolol has been evaluated for pediatric use in a controlled trial in the context of SVT, yet both medications are used frequently. Specific aims of the study: To determine whether propranolol and digoxin differ in the: Incidence of recurrent SVT in infants after 6 months of treatment with propranolol or digoxin Time to first recurrence of SVT in infants treated with propranolol or digoxin. Incidence of adverse outcomes in infants treated with propranolol or digoxin.

This is a two-part, multi-center, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of etripamil NS self-administered by patients who experience an episode of paroxysmal ventricular tachycardia (PSVT) in an at-home setting. Part 1 comprised the conduct of the NODE-301 study up to the date of the adjudication of 150th positively adjudicated PSVT episode and Part 2 comprises the conduct of the NODE-301 study after the completion of Part 1. The RAPID Study (NODE-301 - Part 2) will enroll patients enrolled during Part 1 who had not dosed with the double-blind study drug, or had not discontinued the study before the adjudication of the 150th positively adjudicated PSVT episode in Part 1, and patients enrolled into the study following the completion of Part 1. Enrollment will continue until and for approximately 6 months after the date of the adjudication of the 180th positively adjudicated PSVT episode. The study will include the following visits: A Screening Visit, A Test Dose Randomization Visit, Monthly Follow-up Visits, A Randomized Treatment Period, A Randomized Treatment Period Follow-Up Visit, An Open-Label Treatment Period, and A Final Study Visit.
