Beyond Symptoms: Rhythm Surveillance in Congenital Heart Disease

Q: What does this research mean for the field?

Arrhythmias in congenital heart disease are common, poorly predicted by symptoms, and more effectively detected by prolonged 7-day monitoring compared to standard 24-hour Holter monitoring, leading to comparable rates of treatment changes in both symptomatic and asymptomatic patients. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Key Points

To evaluate different rhythm surveillance strategies in detecting arrhythmias among patients with congenital heart disease (CHD).
Retrospective analysis of 552 CHD patients
Used 7-day patch rhythm monitoring
Categorized patients as symptomatic or asymptomatic
Analyzed initial 24 hours as standard Holter monitoring
Arrhythmias detected in 64.8% of symptomatic and 68.5% of asymptomatic groups
Highest detection rate was 66.1% with 7-day monitoring
Significant arrhythmias found in 16.9% of symptomatic and 19.2% of asymptomatic patients
Weak symptom-arrhythmia correlation, significant only in the asymptomatic group
Treatment change rate was 9.4%.
