Implication

Supports HRV monitoring to stratify arrhythmic risk in T2DM; extends evidence linking reduced variability to autonomic neuropathy and poor glycemic control.

Key Points

To investigate how heart rate variability (HRV) can predict arrhythmias in individuals with type 2 diabetes.
Assessment of heart rate variability through R–R intervals and 24-hour Holter monitoring
Analysis of nonlinear HRV indices to evaluate autonomic dysfunction
Correlation of HRV with cardiac autonomic neuropathy and glycaemic control
Reduced HRV correlates with increased severity of cardiac autonomic neuropathy.
Chronic hyperglycaemia and oxidative stress lead to diminished parasympathetic tone.
HRV analysis identifies individuals at higher risk for arrhythmias, suggesting targeted interventions.

Structured PICO

Does heart rate variability assessment predict arrhythmias in patients with type 2 diabetes mellitus?

Population

Patients with type 2 diabetes mellitus

Intervention

Heart rate variability (HRV) assessment

Outcome

Arrhythmogenic risk and sudden cardiac death

Heart rate variability assessment serves as a sensitive, non-invasive marker to predict arrhythmic risk and autonomic dysfunction in patients with type 2 diabetes.
