Active clinical trials for "Atrial Premature Complexes"

A Randomized, double-blind, placebo-controlled, four dose groups, post-marketing clinical trial, to evaluate the efficacy and safety of Wenxin granules in treating atrial premature beats by different doses,to provide a scientific basis for rational clinical use of drug.

"Chang Gung ECG Abnormality Detection Software" is a is an artificial intelligence medical signal analysis software that detect whether patients have abnormal ECG signals of 14 diseases by static 12-lead ECG. The 14 diseases were Long QT syndrome Sinus bradycardia Sinus Tachycardia Premature atrial complexes Premature ventricular complexes Atrial Flutter, Right bundle branch block Left bundle branch block Left Ventricular hypertrophy Anterior wall Myocardial Infarction Septal wall Myocardial Infarction Lateral wall Myocardial Infarction Inferior wall Myocardial Infarction Posterior wall Myocardial Infarction The main purpose of this study is to verify whether "Chang Gung ECG Abnormality Detection Software" can correctly identify abnormal ECG signals among patients of 14 diseases. The interpretation standard is the consensus of 3 cardiologists. The results of the software analysis will be used to evaluate the performance of the primary and secondary evaluation indicators.

Single-channel electrocardiograms (lead I of 12-lead surface ECG; 30 seconds) will be collected from subjects/patients at 11 clinical centers in Germany to train an Artificial Intelligence in the automatic diagnosis of regular and irregular heart rhythms. Heart rhythms of interest are normal sinus rhythm (SR), atrial fibrillation (AF), atrial premature beats (APBs), ventricular premature beats (VPBs), and nonsustained ventricular tachycardia (VT). Per diagnosis, 20,000 ECGs are required, for a total of 100,000 ECGs to be obtained from approximately 10,000 subjects/patients.

A prospective cohort study to evaluate the association between various triggers encountered in daily life and induction of atrial arrhythmias (atrial fibrillation, atrial flutter, atrial tachycardia and premature atrial contractions) with the use of long-term monitoring devices. The collected data of personalized triggers and risk factors will be used to define the individual phenotype of atrial arrhythmia.

Premature atrial contractions (PACs) and premature ventricular contractions (PVCs) are observed in the majority of individuals monitored for more than a few hours. Although the clinical course of PACs and PVCs is usually benign, it has been described that high PAC or PVC frequency causes various comorbidities and worsens outcomes in different patient groups. For example, PACs can initiate episodes of atrial fibrillation, and PAC count is highly specific in predicting diagnosis of incident atrial fibrillation. Increasing PVC frequencies are an important predictor of incident heart failure. While conventional wisdom dictates that common environmental exposures determine PAC and PVC frequencies, this has not born out in rigorous studies. Whether PAC and PVC frequencies may have genetic underpinnings remains unknown. Comparisons between identical twins and fraternal twins can provide estimates of heritability. Fraternal twins are an ideal control because, like identical twins, they share a womb, have the same birthday, and their environment while growing up are as similar as between identical twins. However, while identical twins share approximately 100% of the same inherited DNA, fraternal twins share, on average, about 50%. By monitoring identical and fraternal twins with portable electrocardiograms (ECGs), we will be able to count the PACs and PVCs over a consecutive timespan to describe the familial aggregation of these complexes. This, to our knowledge, would be the first study to compare PAC and PVC frequencies in identical and same-sex fraternal twins, providing the first assessment of how genetical inheritance may influence cardiac ectopy burdens.

The aim of the proposed study is to determine if individuals with excessive supraventricular ectopic activity (ESVEA) on Holter recording should be subjected to prolonged screening with Event loop recorder in order to detect previously undiagnosed Atrial fibrillation / flutter. Other biomarkers such as plasma biomarkers, high-end echocardiography and assessment of blood pressure and atrial stiffness will be studied and compared in ESVEA and control group as well as progression of atrial cardiomyopathy in ESVEA patients.

Despite recreational cannabis now being legal in 23 states, where more than 100 million Americans reside, studies on the actual health effects are limited. This study is a randomized trial, where each participant will be instructed to consume or avoid cannabis on randomly assigned days during a 14-day monitoring period. The goal of this study is to answer the question: "Does cannabis use increase the frequency of 'early' and abnormal heart beats?" During the 14-day period, participants will wear an external heart monitor, a glucose monitor, and a fitness tracker to track heart rhythm, glucose levels, step counts, and sleep health. Participants will use a mobile app or a text messaging service for daily instructions/reminders on cannabis use, and short surveys. The investigators ask that participants smoke or vape cannabis at least once on days they are instructed to consume cannabis. Compelling evidence of heart and other health effects would be important to the clinical care of our patients.

it is a prospective, randomized, double-blinded, crossover study on the use of an association of omega 3 fatty acids, astaxanthin, vitamin E and hawthorn (ritmonutra) in subject affected by symptomatic supraventricular ectopic beats without structural heart disease. The study will evaluate the reduction of the number of supraventricular ectopic beats and symptoms related.

There is accumulating evidence for obstructive sleep apnea (OSA) as an independent risk factor for paroxysmal atrial fibrillation and for high recurrence rates of atrial fibrillation after ablation therapy. We have previously shown that simulated OSA triggers premature atrial beats (PABs) by acute changes in intra-thoracic pressure. Most episodes of atrial fibrillation are initiated by PABs. However, the origin of PABs induced by intra-thoracic pressure swings is unknown. This study investigates the origin of premature atrial beats induced by intra-thoracic pressure changes that simulate obstructive sleep apnea in patients with atrial fibrillation.

The primary objective of this research is to determine whether oral magnesium supplementation in healthy, community-living individuals will be associated with reductions in the burden of arrhythmias in the upper chambers of the heart (supraventricular arrhythmias).
