To examine the prevalence of NSVT on extended ambulatory monitoring and analyze its association with cardiovascular disease, as well as its impact on clinical management, particularly in patients with congenital heart disease.
Key Findings:
NSVT prevalence was 6% among 2,805 patients evaluated, indicating a notable detection rate.
Average day of NSVT detection was 4.3 days with an average monitoring duration of 7.5 days.
Average NSVT rate was 149 bpm, with a maximum of 173 bpm, suggesting variability in arrhythmia severity.
66% of patients required a second monitor, with 35% of those having NSVT detected, highlighting the need for extended monitoring.
Interpretation:
Extended ambulatory monitoring increases the detection of NSVT, particularly beyond the standard 48-hour period, suggesting its clinical relevance in managing patients with congenital heart disease and potentially influencing treatment decisions.
Limitations:
Single-center study may limit generalizability; findings may not apply to broader populations.
Retrospective design may introduce selection bias, affecting the reliability of the results.
Conclusion:
The study supports the use of extended monitoring for detecting NSVT in patients with congenital heart disease, which may lead to significant management changes.
Population-based cohort shows higher rates of cardiac arrhythmias and coronary artery disease following nonhospitalized infections, with sex-specific differences.
