Device And Method For Peri-Hisian Pacing And/Or Simultaneous Bi-Ventricular or Tri-Ventricular Pacing For Cardiac Resynchronization

摘要

The present invention provides a pacing device and method that allows for preferential right atrial, at or near the His bundle, and ventricular pacing, either individually or in combination, including tri-ventricular pacing. The pacing device includes a power source and one or more logic circuits allowing for programmable delivery of pacing to any combination of the right atria, the para-Hisian region, and the right and/or the left ventricles. The pacing device allows the user to select which site(s) to pace as well at the appropriate relative timing of pacing impulse delivery to any of these three previously mentioned sites. The device is constructed and arranged to be combined with an atrial sensing/pacing electrode to allow for atrio-ventricular sequential tri-ventricular pacing or variants of such. Also, a defibrillator lead can be incorporated into the device to allow for protection from ventricular arrhythmias and sudden death.
