Ultra-high-frequency ECG for Prediction of Left Ventricular Remodeling
Czechia368 participantsStarted 2021-05-01
Plain-language summary
The main goal of the project is to prove that ultra-high-frequency ECG (UHF-ECG) can be used as a diagnostic tool that allows the prediction of patients susceptible to the negative effect of right ventricular myocardial pacing. The prediction will be based on the assessment of electrical dyssynchrony and local depolarization durations of left ventricular depolarization emerging during right ventricular pacing. If proved to be valid in left ventricular negative remodeling prediction, UHF-ECG-derived parameters of ventricular dyssynchrony could be used as markers allowing a lead placement optimization during an implant procedure. This information can help the operator to identify patients with the urgent need for physiological pacing (HB or LBBp) and patients in which a right ventricular myocardial pacing is sufficient and will not lead to the development of the negative left ventricular remodeling.
