Falluntersuchungen zur nicht-linearen Dynamik der Arrhythmia absoluta
… present a uniform extent of variability of the ventricular response exemplifying periodicities and more complex fluctuations, due to varying number and shape of atrial wavelets and aberrant conduction in the AV-junction. It was sought to categorise different degrees of complexity introducing an …

VALUTAZIONE DI UNA COMPONENTE A BASSA FREQUENZA DELLA VARIABILITÀ DELLA PRESSIONE ARTERIOSA SISTOLICA IN PAZIENTI CON FIBRILLAZIONE ATRIALE PERSISTENTE E SUA SUCCESSIVA ULTERIORE VALUTAZIONE MEDIANTE LINGUISTIC ANALYSIS
… a common arrhythmia characterized by irregular ventricular response. During AF, beat-to-beat variability of arterial pressure (AP) is increased because of continuous changes in filling time, stroke volume and contractility. Only a few studies have analyzed short-term AP variability during AF but …

Modeling the Impact of Heart Rate Variability on Blood Pressure in Simulated Atrial Fibrillation Using the BioGears Physiology Engine
… by chaotic atrial activation and irregular ventricular response. While its electrophysiologic mechanisms are well studied, the systemic consequences of rhythm irregularity, particularly its impact on blood pressure variability (BPV), remain poorly understood. This study uses the BioGears …

RUOLO DELLA STIMOLAZIONE VAGALE SULLA PROLIFERAZIONE DEI FIBROBLASTI CARDIACI IN VIVO IN MODELLO ANIMALE DI FIBRILLAZIONE ATRIALE.
Introduction: Cardiac fibrosis is a pathological response that causes abnormalities in cardiac conduction and mechanical function, thereby contributing to the pathophysiology of a variety of cardiac conditions, including hypertrophy, failure, and arrhythmias. Atrial fibrillation (AF) is the most …
