Hypothesis
Can the Vitatron™ Selection® device effectively prevent atrial fibrillation in patients with brady-tachy syndrome?
Conclusion
The Vitatron™ device reliably detects atrial arrhythmias and significantly reduces their occurrence in patients with brady-tachy syndrome.
Supporting Evidence
- 59 atrial arrhythmia episodes were recorded with a correlation coefficient of 0.96 between Holter and pacemaker data.
- PACs decreased from 83±12/day to 2.3±0.8/day.
- AF episodes reduced from 46±7/day to 0.12±0.03/day.
- AF burden decreased from 93%±6% to 0.3%±0.06%.
Takeaway
This study shows that a special pacemaker can help people with a heart rhythm problem by stopping their heart from racing too much.
Methodology
15 patients with a DDDRP pacemaker were monitored for atrial arrhythmias and their effectiveness was evaluated over a follow-up period of 24±8 months.
Potential Biases
Potential selection bias due to the small number of patients and their specific characteristics.
Limitations
The study had a small and highly selected sample size, limiting generalizability.
Participant Demographics
9 males and 6 females, mean age of 71±5 years, NYHA class I-II.
