  • Research summary

    It has been well established over the past two decades that older children and adults with previous surgery for congenital heart disease (CHD) represent an at-risk population for abnormal heart rhythms (arrhythmias), including ventricular tachycardia (VT), ventricular fibrillation (VF) and sudden cardiac death (SCD)[1, 2]. This risk is believed to be primarily due to a combination of underlying inherent myocardial conduction abnormalities and iatrogenic factors, through the presence of fibrotic scar tissue from reparative surgery.\n\nFollowing surgery, many children with CHD can lead normal lives, although some develop arrhythmias as adults, potentially resulting in sudden cardiac death (SCD). Currently, no single predictive measure exists to detect CHD patients at heightened risk of developing arrhythmias, although candidates are regularly proposed, including QRS prolongation and most recently, the QRS Vector Magnitude (QRSvM).\n\nThis project aims to test the validity of these and other parameters in predicting arrhythmias in the regional population of CHD patients managed at the Freeman Hospital, Newcastle upon Tyne, and evaluate their potential as biomarkers and thus identify high-risk patients that may benefit from interventions, such as medications, pacemakers and defibrillators that prevent and treat arrhythmias.\n\n1.\tNollert G., Fischlein T., Bouterwek S., Böhmer C., Klinner W., Reichart B.
