Stanford Cardiac Invasive Electrophysiology Novel Computer Experience

Patients will be recruited prospectively from among those undergoing ablation for atrial fibrillation (AF) or atrial tachycardias (AT) which may be reentrant or focal. Each patient will undergo careful data collection, including electrogram data and sites of ablation lesions. Ablation will proceed in operator-dependent fashion, and will not be modified ...

Phase N/A

Effect of His Bundle Pacing in Treatment of Slow Arrhythmia on Function of Left Atrial and Ventricle

The purpose of this study is to conduct a comparison in patients' cardiac function, ECG, and pacemakers' threshold value, time limit and so on among dual chamber pacemaker, and HBP. The clinic trial is about to conduct pacemaker implantation in 84 participants, which distribute into dual chamber pacemaker, HBP 2 ...

Phase N/A

The Canadian National Long QT Syndrome Registry

Methods Patients with positive LQTS diagnosis and their family members reviewed in collaborating Canadian Inherited Arrhythmia Clinics will be invited to participate in the registry. Optional bio bank donation will be offered. Consenting participants will have blood work drawn in their local outpatient laboratory. Bio banking at other collaborating centres ...

Phase N/A

Determine the Incidence of Long QT Amongst a Large Cohort of Subjects Diagnosed With Unilateral or Bilateral Sensorineural Hearing Loss.

The purpose of this study is to determine the true incidence of long QT (LQT) amongst a large cohort of subjects diagnosed with unilateral (right/left) or bilateral sensorineural hearing loss. The goal of this study is to answer the following questions: What is the incidence of an abnormal ECG (QTc ...

Prospective Identification of Long QT Syndrome in Fetal Life

Ascertainment of LQTS, an inherited arrhythmia disorder in a group of conditions known as the channelopathies, is challenging before birth. Recently, in a retrospective study it was reported that a gestational age dependent bradycardia allows a much higher recognition of genotype positive LQTS than the standard obstetrical gestational age independent ...

Phase N/A

Using Cardiovascular Magnetic Resonance Tissue Characterisation and Wearable Technology to PREDICT Clinical Outcomes Response to Therapy and Arrhythmias in Hospitalised Heart Failure Patients

PREDICT-HF a low risk single centre observational study in which 150 consecutive patients admitted with a new, primary diagnosis of heart failure undergo advanced CMR to non-invasively establish their individual myocardial tissue characteristics during their initial presentation. All study participants will be invited to participate in an optional heart rhythm ...

Phase N/A

Effect of His Bundle Pacing in Treatment of Slow Arrhythmia on Function of Left Atrial and Ventricle in Short Term

The purpose of this study is to conduct a comparison in patients' cardiac function, ECG, and pacemakers' threshold value, time limit and so on among dual chamber pacemaker and HBP. The clinic trial is about to conduct pacemaker implantation in 84 participants, which distribute into dual chamber pacemaker, HBP 2 ...

Phase N/A

Characterization of Arrhythmia Substrate to Ablate Persistent Atrial Fibrillation

The optimal CA strategy for persistent AF remains unknown. Current data highlight the need for a better understanding of the substrate and mechanisms of arrhythmia maintenance in this population. Atrial scar-based catheter ablation has recently emerged as a promising strategy for ablation of AF. However, the available data has limitations ...

Phase N/A

Feasibility of Improving Risk Stratification in Brugada Syndrome

It is estimated that approximately 600 apparently fit and healthy individuals aged under 35 years die suddenly in the UK every year Many of these sudden cardiac deaths (SCD) in the young are the result of inherited cardiac conditions (ICC), the majority of which are the direct consequence of single ...

Phase N/A

Left Atrial Thrombus on Transesophageal Echocardiography

Atrial fibrillation (AF) and atrial flutter (AFI) increase the risk of thromboembolic events by promoting clot formation in the left atrium (LA). Transesophageal echocardiography (TEE) is routinely used to exclude the presence of an LA thrombus before AF/AFI ablation or cardioversion. So far, it has not been established what is ...
