EGM-based AV optimization may simplify CRT programming; leaves open prospective validation against echo or clinical outcomes.
Does AV delay programming based on intracardiac electrogram intervals accurately predict optimal AV delay for hemodynamic optimization compared to other noninvasive methods in patients at CRT implant?
An electrogram-based optimization method accurately predicts optimal AV delay during CRT, potentially obviating the need for time-consuming echocardiographic optimization.
