Biventricular pacing and heterogeneity of ventricular repolarization in heart failure patients

The aim of our study was to evaluate the effect of cardiac resyncronization therapy (CRT) on QT dispersion (QTd), JT dispersion (JTd) and transmural dispersion of re-polarization (TDR), markers of heterogeneity of ventricular repolarization in a study population with severe heart failure.

Heart rate variability analysis in postural orthostatic tachycardia syndrome: a case report

The authors present a case of 36 year old male patient with idiopathic postural orthostatic tachycardia syndrome (POTS) diagnosed during head-up tilt testing. Power spectral analysis of heart rate variability (HRV) during the tilt test revealed that the ratio of low and high freque...

Azithromycin-induced QT prolongation in elderly patient

The authors present a case of an elderly patient with idiopathic dilated cardiomyopathy who developed a significative prolongation of the QT interval after two days of treatment with azithromycin for a community-acquired pneumonia. QT prolongation is associated with a high risk of serio...

Does left atrial appendage closure with a cardiac plug system reduce the stroke risk in nonvalvular atrial fibrillation patients? A single-center case series

Background Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and it is associated with an increased stroke risk, due mainly to cardiac embolism from the left atrial appendage (LAA). Percutaneous LAA closure is a method to reduce stroke risk in AF without ...

Blocco interatriale: una diagnosi elettrocardiografica misconosciuta con importanti implicazioni clinico-terapeutiche

Interatrial blocks, characterized by P-wave duration ≥120 ms, are a well described but poorly recognized cardiac rhythm disorder. They are caused by a conduction delay between the right and left atria and occur in pandemic proportions in unselected patients. Interatrial blocks correlate ...
