To acquire, amplify, digitize, and record atrial intracardiac electrophysiology signals during cardiac electrophysiology studies for the treatment of persistent atrial fibrillation and to use the recorded data to test the performance of an signal complexity visualization algorithm.
The purpose of this study to determine the prognostic value of the Selvester QRS score for perioperative myocardial injury following elective non-cardiac surgery.
A prospective study in paediatric, adolescent and young adult patients aged 7 to 18 years to validate the use of the Apple Watch's electrocardiogram (ECG) function in measuring QT prolongation during and or after cancer therapy.
Mobile battle ground games are widely used in various age groups, there are ocular and cardiac affection that may affect users of this type of action games.
The objective of this multicentre study is to collect operative data on the related clinical functional outcomes and complications and of market approved Alcis electrophysiology catheters to demonstrate safety and performance of these devices in a real-world setting.
The primary objective is to evaluate the safety and technical performance of the CathVision ECGenius® System. The secondary objective is to benchmark the intracardiac electrogram signal quality compared to commercially available systems in patients undergoing assessment and ablation of cardiac arrhythmias.
Atrial fibrillation (AF) is the most common arrhythmia (irregular heart rhythm), affecting 1-2 million people in the UK. AF significantly increases the risk of an AF-related stroke, heart failure and dementia. A significant proportion of people will have no symptoms, and they may only be found to have AF after suffering an AF-related stroke. An electrocardiogram (ECG) uses sensors placed on the skin to record the heart's electrical activity. A 12-lead ECG uses 10 sensors and is the gold-standard (best available test) to detect any abnormal heart rhythm disturbances. Until recently, a 12-lead ECG showing an irregular heart rhythm was required to make a diagnosis of AF but as AF episodes are often short and unpredictable it may be missed. Therefore, a small device that continuously records heartbeat and heart rhythm could make the diagnosis of arrhythmias and AF much quicker and easier. Accessories such as watches or rings - referred to as wearable devices - have extremely good sensors that measure pulse rate by detecting small changes in skin colour during each heartbeat and can perform a single-lead ECG. Algorithms built in the wearable devices can identify irregular heart rhythms, such as atrial fibrillation. The purpose of this study is to test two new wearable devices - the Skylabs CART-I ring and the Apple Watch - in detecting abnormal heart rhythm recording and recording ECGs. The investigators plan to recruit 500 patients attending Cardiology Departments in several hospitals in the UK and will ask them to wear the Apple Watch and the CART-I and perform 12-lead ECG with each device (two in total). No extra follow-up visits are required. At the end of the study, the investigators will compare interpretation by two cardiologists of the wearable devices' ECGs and the 12-lead ECGs and look at their ability to automatically detect abnormal rhythms.
The CMR/CT WG of the Italian pediatric cardiology society set up a multi-center observational clinical database of repaired-TOF evaluated. This registry will enroll prospectively patients evaluated by CMR for clinical indication in most of the CHD Italian centers. Data collection will include surgical history, clinical data, imaging data, and also adverse cardiac events for a period of 6 years.
