Prediction of Outcome by Echocardiography in Left Bundle Branch Block

Recruiting now

Conditions studied: Left Bundle-Branch Block

In brief

Patients with left bundle branch block have an increased risk for the development of heart-failure and death. However, risk factors for unfavorable outcomes are still poorly defined. This study aims to identify echocardiographic parameters and ECG characteristics by machine learning in order to develop individual risk assessment
