2 results about "Cardiac resynchronization" patented technology

The invention relates to a heart support system comprising: - an intraventricular implantable heart pump, - a therapy unit, - at least one lead intended to be placed on the outer wall of the heart, wherein the therapy unit comprises a heart pump management function, a pacing function and / or a defibrillation function. The therapy unit is configured to: - perform an impedance cardiography measurement between the at least one lead and a metal component of the heart pump to determine the following hemodynamic parameters: - a cardiac electromechanical delay determined from the impedance cardiography measurement, - a blood filling duration of the heart determined from the impedance cardiography measurement, - a blood ejection duration of the heart determined from the impedance cardiography measurement, and - a variation over time of the right ventricle and / or left ventricle volume.

Multiple external electrodes are used to monitor cardiac electrical activity from the patient's tissues. One or more cardiac measurements of the patient are generated based on the monitored electrical activity. If the patient has right bundle branch block, the one or more cardiac measurements are used based on a first global synchrony measure to determine whether the patient is a candidate for a cardiac resynchronization therapy (CRT) device. If the patient does not have right bundle branch block, the one or more cardiac measurements are used based on a second global synchrony measure to determine whether the patient is a candidate for a cardiac resynchronization therapy (CRT) device.
