Key Points

  • To develop and evaluate an implantable synchronous cardiac pacemaker designed for the long-term management and correction of complete heart block.
  • Implanted the synchronous pacing device in canine models of complete heart block for observation periods lasting up to eight months.
  • Evaluated device tracking and pacing performance across normal sinus rhythm and atrial arrhythmias using continuous electrocardiographic monitoring.
  • Maintained stable synchronous ventricular pacing during both normal sinus rhythm and atrial arrhythmias throughout follow-up periods of up to eight months.
  • Restored animals to normal physical activity with full tolerance to exercise and no observed device-related failures.

Abstract

An implantable, synchronous cardiac pacemaker for long-term correction of complete heart block has been developed. It has been successfully used in dogs for periods up to eight months. The performance of the pacemaker during normal sinus rhythm and atrial arrhythmias is illustrated with electrocardiograms. After implantation of the pacemaker, the dogs have returned to completely normal activity and have tolerated all physical exercises well. see figure in the PDF file
