Filter by:The goal of this interventional clinical trial is to establish a comprehensive, structured database that includes photoplethysmography (PPG) measurements with simultaneously recorded electrocardiography (ECG) data to evaluate the FibriCheck Algorithm in patients with heart rhythm disorders.
This study is a multicenter, prospective and randomized controlled study. The experiment includes a 1-week screening period (1 week before dialysis) and a 7-week treatment period (1-4 weeks of dose drip period and 5-7 weeks of evaluation period). During the screening period, all patients were randomly divided into the control group and the treatment group. On the non-dialysis day of the treatment period, the treatment group was given a certain dose of sodium zirconium silicate, and the blood potassium value was measured before and after each dialysis to maintain the blood potassium at 4.0-5.0mmol/L before dialysis. At the same time, 12-lead ECG and 24-hour Holter were completed at the first and last dialysis during the treatment period, and finally the ECG stability and its relationship with blood potassium were evaluated.
This is a prospective, non-randomized, multi-center, real-world post-market study to collect and evaluate data regarding the performance of the enhanced atrial fibrillation detection algorithm of the Assert-IQTM Implantable Cardiac Monitor (ICM) device.
The goal of this interventional study is to evaluate the risk of atrial fibrillation (AF) and other cardiac arrhythmias and diseases in breast cancer patients treated with radiation therapy (RT). In addition to regular follow-up of patients by the radiation oncologist for 5 years, cardiovascular screening at the end of follow-up, combining the use of a connected watch and a cardiological check-up, could make it possible to identify precisely the types and frequencies of these sometimes asymptomatic, and probably underestimated, cardiac diseases. The main questions it aims to answer are: - To assess the incidence of AF and other cardiac arrhythmias and diseases occurring within 5 years after RT - To evaluate absorbed doses in the heart and cardiac substructures (chambers, conduction nodes, coronaries, pulmonary veins) based on auto-segmentation models developped with deep learning algorithms - To investigate whether the risk of AF and other cardiac arrhythmias and diseases is associated with cardiac irradiation characterized by these absorbed doses (dose-response relationship) Participants will be included between 2023 and 2025, 5 years after their RT: - Retrospective data collection will be based on a medical questionnaire designed to identify cardiac pathologies present prior to RT and those having occured in the past, between RT and 5 years post-RT. - Cross-sectional data collection will be based on screening for cardiac pathologies using a connected watch worn for 1 month (silent AF screening) and a cardiology consultation (including ECG and echocardiography) to identify cardiac pathologies at 5 years post-RT possibly not identified in the retrospective data collection.
The purpose of this study is to investigate whether a 3 month treatment course of low-dose Colchicine decreases the recurrence of Atrial fibrillation (AF) after electrocardioversion (ECV) in patients with AF.
Noninvasive evaluation of the electrical status of the heart is based on the standard ECG but remains suboptimal due to difficulties with arrhythmia characterization and location. Electrocardiographic Imaging (ECGI) provides maps of cardiac electrical excitation in relation to the anatomy of the heart using an extensive number of electrodes from the body surface. The applicant will develop a systematic evaluation of the ECGI as a tool to detect cardiac regions of interest in cardiac arrhythmias.
ATHENA is a prospective, multicenter, non-randomized post-market study. All patients will be treated according to the standard care followed by each center. The protocol requires enrollment of consecutive patients from each center, according to eligibility criteria. During the 12 months follow-up period, clinical atrial fibrillation recurrence, occurrence of all kind of atrial arrhythmias and of all Adverse Events in the study population will be collected. The purpose of this study is to prospectively evaluate during time a large population of patients with an indication for ablation of AF, collecting data on procedural success in the acute and medium- to long-term follow-up. The primary objective of the study is the determination of up to 20 clinical and procedural parameters predicting the recurrence-free at the medium-long term follow-up in consecutive patients undergoing atrial fibrillation ablation through a standard of care pathway. The success of the ablation is defined in terms of percentage of patients free from any clinical atrial arrhythmia at a 12-month follow-up from the procedure.
A prospective study in paediatric, adolescent and young adult patients aged 7 to 18 years to evaluate the agreement between QTc measured using 12 lead electrocardiogram (ECG) and the wearable device ECG.
Mitral valve prolapse (MVP) is associated with malignant ventricular arrhythmias (VA) and sudden cardiac death. A proper electrophysiological and echocardiographic characterization of this population is missing. Moreover, the effects of mitral valve repair on the arrhythmic burden are still matter of debate. The investigators sought to explore the role of the arrhythmic substrate in the risk stratification of patients with MVP and to assess whether mitral surgery is followed by a significant modification of the baseline arrhythmic pattern.
This data collection is designed to provide evidence for the safety, performance, and clinical benefit of BIOTRONIK's EP products. Additionally, residual risks will be monitored and newly emerging risks identified.
