An Implantable, Synchronous Pacemaker for the Long-Term Correction of Complete Heart Block

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.
