Summary
Rate-responsive pacing using activity sensing in children is a reliable and effective physiological pacing method. This approach enhances heart rate and exercise capacity, improving clinical status without arrhythmias.
Area of Science:
- Pediatric Cardiology
- Biomedical Engineering
- Electrophysiology
Context:
- Physiologic pacing aims to preserve atrioventricular synchrony.
- In children, cardiac output can be enhanced by heart rate increase during exercise.
- Physiologic pacing modes include DDD, DDDR, and SSIR, focusing on hemodynamic improvement.
Purpose:
- To evaluate the effectiveness and reliability of physiological pacing modes in children.
- To assess rate-responsive pacing with activity sensing in pediatric patients.
Summary:
- This study reports on 70 children paced using physiological modes: 51 in SSIR, 16 in DDD, and 3 in DDDR.
- DDD pacing showed a high failure rate (47.75% at 48 months) due to crosstalk and sensing issues.
- Rate-responsive pacing with activity sensing in 26 children demonstrated significant increases in heart rate and work capacity, improving clinical status without arrhythmias.
Impact:
- Rate-responsive pacing with activity sensing is an adequate and effective physiological pacing strategy for children.
- This pacing mode enhances exercise capacity and clinical well-being in pediatric patients.
- Findings support the use of activity-sensing rate-responsive pacing for improved pediatric cardiac function.
