The purpose of this study is to investigate skin sympathetic nerve activity (SKNA) in correlation with cardiac arrhythmias and/or heart failure.

This is a 3-day study comparing pyridostigmine versus placebo in the treatment of postural tachycardia syndrome (POTS). The researchers expect pyridostigmine to improve tachycardia and stabilize blood pressure.

The primary objective of this study is to determine whether etripamil nasal spray (NS) 70 mg is superior to placebo at terminating episodes of PSVT in an outpatient setting.

The purpose of this study is to measure the effect on ventricular ectopy, safety, tolerability and pharmacokinetics of S48168 (ARM210) compared with placebo in participants with Type 1 Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT1).

The purpose of this study is to demonstrate the safety and effectiveness of ventricular ablation therapy using the FlexAbility Sensor Enabled Ablation Catheter in patients with drug-refractory monomorphic ventricular tachycardia in whom ventricular tachycardia recurs despite antiarrhythmic drug therapy or when antiarrhythmic drugs are not tolerated or desired.

The purpose of this study is to determine if common genetic variants that underlie the QT interval are also associated with medication-induced torsade de pointes (TdP).

The purpose of this study is to evaluate if the patient/participant will self-enter clinical survey information into an iPad or choose to enter the same information by paper and pen for use in clinical research.

The study aims to evaluate if a hybrid semi-supervised remote monitoring three month strength and aerobic exercise training program can be as efficacious as in-person exercise training has previously demonstrated. 

The purpose of this research study is to better understand what causes POTS. We believe that a number of different causes of POTS exist and that detailed testing can demonstrate the different causes. Knowing what causes POTS in a particular patient will be helpful in choosing the right treatment strategy for that particular patient in the future.

The purpose of this study is to test the feasibility of using a novel wearable biosensor and mobile health monitoring platform to capture patients’ physiology, functional capacity and assessment of symptoms, thereby building a profile of Positional Orthostatic Tachycardia Syndrome (POTS) while excluding more serious cardiac, neurological and endocrine causes for their symptomatology. We hypothesize that as a non-fatal condition, a complete physiological profile of the POTS patients can be built entirely remotely therefore avoiding the need for these patients to visit the hospital and clinic.

This study is designed to investigate whether the treatment of non-anemic iron deficiency with intervenous iron sucrose will result in decreased symptom reporting and improved cardiovascular indices in adolescents (age 12-18) with Postural Orthostatic Tachycardia Syndrome (POTS).

The aims of this study will be to measure changes in postural orthostatic tachycardia syndrome (POTS) symptoms, functional disability and catastrophizing subsequent to patients’ participating in the 2-day Pediatric Pain Rehabilitation Program.

The goal of this study is to gain a better understanding of the sleep and fatigue complaints of adolescent POTS patients by objectively measuring sleep with actigraphy prior to and after attending the Pain Rehabilitation Center (PRC) 3 week program. A questionnaire will be administered to assess subjective sleep complaints and correlate them with objective findings.

The aim of this study is to determine the outcomes of catheter ablation before transcatheter PVR among patients with Tetralogy of Fallot (TOF, a specific type of congenital heart defect). It is hypothesized that a combination of successful catheter ablation and transcatheter PVR placement will result in a reduction in a conventional risk score calculation (and consequently, fewer patients meeting criteria for primary prevention ICD placement) owing to a combination of VT circuit elimination and favorable RV remodeling.

The purpose of this study is to compare the rate of arrhythmia-induced events between paediatric Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT) patients with and without implantable cardioverter defibrillator (ICDs), and to determine the quality of life and psychosocial functioning of paediatric CPVT patients with and without ICDs.

The purpose of this study is to assess the hydration status via body impedance of patients suffering from postural orthostatic tachycardia syndrome.

The purpose of this study is to gather information about symptoms of autonomic dysfunction, depressive and anxiety symptoms, health behaviors, social support, and ability to do everyday tasks.

This study aims to investigate whether the treatment of non-anemic iron deficiency with intravenous iron sucrose will result in decreased symptom reporting and improved cardiovascular indices in patients with Postural Orthostatic Tachycardia syndrome (POTS).

The purposes of this study are to compare the functional connectivity in adolescent patients with Postural Orthostatic Tachycardia Syndrome (POTS) both with and without chronic pain, to those with chronic pain alone, to that of healthy controls; to evaluate whether there is a change in functional connectivity following participation in an intensive rehabilitation-oriented program previously demonstrated to have excellent outcomes with regard to functional recovery and symptom control; and to correlate outcomes using standardized symptom and function rating scales to imaging findings.

The purpose of this study is to gain a better understanding of the sleep quality and fatigue complaints of adolescent orthostatic intolerance (OI) and postural orthostatic tachycardia syndrome (POTS) patients by objectively measuring sleep duration and timing with actigraphy. Sleep questionnaire will be administered to assess subjective sleep complaints and correlate them with objective findings.

The purpose of the MODULAR ATP Clinical Study is to demonstrate safety, performance, and effectiveness of the Modular Cardiac Rhythm Management (mCRM) Therapy System.

The purpose of this study is to identify and characterize heart rhythm disorders including atrial arrhythmias such as atrial fibrillation, ventricular arrhythmias such as ventricular tachycardia, conduction abnormalities, etc. among patients with spontaneous coronary artery dissection (SCAD).

The purpose of this study is to evaluate the feasibility and safety of a management approach that incorporates VT-ablation and S-ICD implantation in secondary prevention patients. This is a single arm prospective study with 30 patients eligible for implantation of an ICD for the secondary prevention of sudden cardiac death.

If the efficacy of 3,4-diaminopyridine (3,4-DAP) can be demonstrated in this study, the use of 3,4-DAP alone and in combination with other agents such as pyridostigmine and L-DOPS would be further evaluated in a double-blind randomized placebo-controlled cross-over study

The aim of this study is to examine the role of mast cell mediators in children with allergic disorders in a two part study. Part 1 of the study will prospectively obtain the values of mast cell mediators, including 2,3 dinor 11β-PGF2α, n-MH, and LTE4 in the urine of a healthy pediatric reference population. Part 2 of the study will prospectively evaluate the urine concentrations of mast cell mediators in a cohort of pediatric allergic disorder patients including asthma, allergic rhinoconjunctivitis, eczema, urticaria, systemic anaphylaxis, and mast cell disorders, as well as POTS (postural orthostatic tachycardia syndrome). Comparisons of these ...

The purpose of this study is to learn about the effect of atrial fibrillation on memory and thinking. This study helps us to determine how often memory problems occur in patients with atrial fibrillation and identify factors that influence changes in memory and thinking.
