Association between ultra-short-term heart rate variability and atrial fibrillation in heart failure population: a protocol for a prospective observational cohort study
Prospective observational cohort study examines the link between ultra-short-term HRV and atrial fibrillation risk in heart failure patients, indicating potential clinical implications.
Key Points
This study finds a potential association between ultra-short-term heart rate variability and atrial fibrillation in heart failure patients.
Primary endpoints include atrial fibrillation and flutter, along with all-cause mortality in participants with reduced left ventricular ejection fraction.
The study employs a prospective observational cohort design to assess the relationship between heart rate variability and atrial fibrillation.
The findings could highlight the importance of early autonomic assessment in heart failure management and risk stratification.
