Can we better predict sudden cardiac death risk from an ECG?

Investigation of mechanisms of T wave generation and the identification of dynamic ECG biomarkers of myocardial electrical instability

Internal cardiac defibrillators can prevent dangerous heart rhythms by delivering a shock to the heart to restart normal pacing. However, it is difficult to accurately predict which patients will develop a lethal heart rhythm and should receive a defibrillator. Professor Pier Lambiase and colleagues at University College London are working to develop better markers for sudden cardiac death risk. They will analyse the electrocardiogram (ECG) traces of patients at risk of dangerous heart rhythms and look at new and novel features on the ECG that will better predict which patients are more likely to develop dangerous heart rhythms or die unexpectedly.
