Summary
Ventricular late potentials (LP) are rare in hypertensive patients without left ventricular hypertrophy (LVH). Their incidence increases with eccentric LVH, correlating with ventricular arrhythmias in concentric LVH.
Area of Science:
- Cardiology
- Electrophysiology
- Hypertension Research
Context:
- Hypertension is a significant risk factor for cardiovascular complications.
- Left ventricular hypertrophy (LVH) is a common consequence of chronic hypertension.
- LVH is associated with an increased risk of ventricular arrhythmias.
Purpose:
- To investigate the incidence of ventricular late potentials (LP) in hypertensive patients.
- To explore the relationship between LP and ventricular arrhythmias in this population.
- To assess the impact of different types of LVH on LP and arrhythmias.
Summary:
- This study analyzed 148 hypertensive patients without coronary artery disease.
- Signal-averaged ECG, echocardiography, and Holter monitoring were used to assess LP, LVH, and arrhythmias.
- LP incidence was low in patients without LVH (5%) and with concentric LVH (13%), but high in eccentric LVH (48%).
- Arrhythmia severity correlated with LP presence in concentric LVH (p < 0.02).
Impact:
- Identifies eccentric LVH as a critical factor for LP and potential arrhythmias in hypertension.
- Highlights the diagnostic value of LP in risk stratification for hypertensive patients.
- Informs clinical management strategies for hypertensive patients at risk of ventricular arrhythmias.
