Multiple serial ECGs aid with the diagnosis and prognosis of Brugada syndrome.

Background: A spontaneous coved-type ST segment elevation in the electrocardiogram (ECG) has long been recognized as a risk stratification tool in patients with Brugada syndrome (BrS). This Type-I ST segment elevation is known to exhibit high dynamicity, fluctuating between coved-type and non-coved ST segment elevation. Our objectives in this study were to: 1) Compare ECG parameters in patients with spontaneous coved-type (Type-I) vs.

Electrocardiographic Markers of Appropriate Implantable Cardioverter-Defibrillator Therapy in Young People with Congenital Heart Diseases.

Implantable cardioverter-defibrillators (ICDs) are increasingly utilized in patients with congenital heart disease (CHD). Prediction of the occurrence of shocks is important if improved patient selection is desired. The electrocardiogram (ECG) has been the first-line tool predicting the risk of sudden death, but data in CHD patients are lacking.
