Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

INTRODUCTION: Electrogram peak-to-peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography-derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained w...

Heart Rate Variability in Heart Failure: Mechanisms, Prognostic Value and Modulation Strategies

Heart rate variability (HRV) is a non-invasive marker of cardiac autonomic regulation that reflects the dynamic interaction between sympathetic and parasympathetic influences on the sinoatrial node. Reduced HRV is a hallmark of autonomic dysfunction and has been consistently asso...
