NCT ID: NCT06276816 Recruiting - Sinus Bradycardia Clinical Trials

Cardiac Denervation Ablation Strategy for Severe Sinus Bradycardia

Start date: September 13, 2023
Phase:
Study type: Observational

This is a prospective clinical observation and registration study. The investigator aimed to evaluate the efficacy and safety of cardiac denervation ablation as a treatment strategy for severe sinus bradycardia.

NCT ID: NCT05903313 Enrolling by invitation - Clinical trials for Myocardial Infarction

A Study to Evaluate Accuracy and Validity of the Chang Gung ECG Abnormality Detection Software

Start date: October 6, 2023
Phase:
Study type: Observational

"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.

NCT ID: NCT05021627 Not yet recruiting - Sinus Bradycardia Clinical Trials

Cardiac Autonomic Nerve Improvement and Pacemaker Therapy in Patients With Sinus Bradycardia

Start date: September 1, 2021
Phase: N/A
Study type: Interventional

This is a multicenter randomized controlled study. By comparing patients with sinus bradycardia undergoing cardiac autonomic ganglion ablation and pacemaker therapy, and long-term follow-up to evaluate its safety and effectiveness after surgery, in order to evaluate the safety and effectiveness of cardiac autonomic ganglion ablation in the treatment of sinus bradycardia.

NCT ID: NCT02462941 Completed - Clinical trials for Atrioventricular Block

Analysis of Adenosine on Sinus and Atrioventricular Nodal Conduction in the Pediatric Transplanted Heart

Start date: July 2015
Phase: Phase 1
Study type: Interventional

Heart transplants save the lives of nearly 500 children in heart failure per year. Columbia is one of the largest pediatric heart transplant centers in the world, averaging 25 transplants per year, and providing ongoing care to nearly 250 children with transplanted hearts. After transplant, children are at increased risk to develop sudden onset of abnormally fast heart rates. This research project will study adenosine, a medication that is routinely used to slow fast heart rates in non-transplanted children (i.e. normal hearts), and its effects on the transplanted heart. Adenosine is often not used in patients with transplanted hearts because, based on prior limited research in adult patients, the standard adult dose may have a longer medication effect, producing a slower heart rate for an undesirable period of time. However, the current alternatives to adenosine treatment are either inappropriate for the pediatric age range, or have increased risk of unwanted side effects. This research project will answer two questions: is adenosine safe to give a child who has had a heart transplant, and will it be effective in treating the fast heart rate? All pediatric heart transplant patients undergo regular heart testing, known as a cardiac catheterization, one or more times per year. Three days before testing, participants will be asked to stop a regular medication, dipyridamole, because it slows the breakdown of adenosine in the body, and may increase its effects. (Of note, all patients that are on dipyridamole are also on aspirin, which gives a second line of heart protection, and will not be stopped.) After regular cardiac catheterization, all patients will already have intravenous (IV) access to give medication. Also, this setting allows the opportunity to have a back-up pacing catheter in the heart, ensuring that there will not be a longer than desired effect from the medication. Adenosine will be given per a low-dose protocol until either the medication effect is seen or the maximum dose is reached. There will be no difference in procedure recovery period time, and patients will resume regular home medications after finishing the test. As Columbia is one of largest pediatric heart transplant centers in the world, studying the effects of adenosine at low doses will benefit the investigators population greatly, either to find a new recommended medication dose, or to provide evidence that this medication is truly inadvisable for the investigators patients. The initial study was completed with all 80 patients enrolled and tested. Subsequent testing is now ongoing on patients in whom dipyridamole was stopped prior to their initial testing with a repeat study without discontinuing the dipyridamole. We anticipate re-testing about 30 of the 80 patients.

NCT ID: NCT02400983 Completed - Heart Failure Clinical Trials

Real Life Automatic Atrial Capture Device Control

Start date: January 2014
Phase: N/A
Study type: Observational

The main objective of this study is to verify the effectiveness of the new ACAP ® Confirm algorithm in the automatic management of atrial capture.

NCT ID: NCT01200667 Active, not recruiting - Asystole Clinical Trials

uPHI: Wireless Body Area Network Core Technology

uPHI
Start date: July 2010
Phase: N/A
Study type: Observational

The application scenario is shown in the figure below: the user utilizes an ECG-based wireless sensor (WiBoC Chipset), and transmit those signals to a mobile-phone device that has an embedded expert system integrated. With the aid of 3G system, a remote healthcare monitoring center receives those uploaded signals and stores into the application server. According to the events from this server, the people on service responses to the emergency and takes the corresponding process.
