Official title

Optimizing Cardiac Resynchronization Therapy With Electrocardiographic Imaging

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

CRT is delivered from two electrodes on opposite sides of the heart \[right (RV) and left ventricle (LV)\] delivering stimulation for more efficient heart beats. There is flexibility in the sequence and temporal staggering of the stimulation from these two electrodes with a different optimum for different patients. However, standard techniques to figure out the optimal stimulation strategy like standard 12-lead surface electrical recording (ECG) or routine ultrasound have failed. The investigators have developed ECG imaging (ECGI) with 250 electrode surface recording combined with CT scan to reconstruct high resolution 4-dimensional panoramic electrical maps of the heart. The study seeks to enroll 56 patients undergoing CRT in a clinical trail to evaluate short and long term impact of using ECGI for optimal programming of CRT.
