Crossover Study of Propranolol vs Ivabradine in POTS

1.0 BACKGROUND Postural tachycardia syndrome (POTS) is a disorder of chronic orthostatic intolerance characterized by symptoms of palpitations, lightheadedness, chest discomfort, shortness of breath, blurred vision, and mental clouding. These symptoms occur during standing and are associated with a marked increase in heart rate (HR) in the absence of hypotension, …

Ambulatory Electrocardiographic Monitoring for the Detection of High-Degree Atrio-Ventricular Block in Patients With New-onset PeRsistent LEft Bundle Branch Block After Transcatheter Aortic Valve Implantation. The "MARE" Study

The purpose of this study is to determine the incidence and predictors of high degree or complete atrioventricular block (AVB) (paroxysmal or persistent) in patients with new-onset persistent left bundle branch block (NOP-LBBB) following transcatheter aortic valve implantation (TAVI) and to evaluate the usefulness of the Reveal LINQ insertable Cardiac …

Prognosis Impact of NSVTs After an AMI (TeVeO Study).

Nowadays, Sudden Cardiac Death (SCD) due to malignant arrhythmias is an important cause of death among acute myocardial infarction (AMI) survivors. Preventive strategies with implantable cardioverter-defibrillators (ICD) are the best clinical option for patients, but associated sociosanitary impact in the National Health Systems and the fact that current implant strategy …
