Publisher Copyright: © 2025 by the authors.; Introduction: Vasovagal syncope is a prevalent condition marked by transient loss of consciousness due to abrupt decreases in systemic blood pressure and/or heart rate. Despite its clinical impact, the underlying haemodynamic mechanis...
AFTER-CA
Ferreira, Mónica; Silva Cunha, Pedro; Felix, Ana Clara; Fonseca, Helena; Oliveira, Mario; Laranjo, Sergio; Rocha, IsabelPublisher Copyright: © 2024 by the authors.; Background: Catheter ablation (CA) is a well-established treatment for atrial fibrillation (AF). However, its effects on autonomic function and underlying mechanisms remain poorly understood. This study investigated autonomic and haemodynamic changes following CA and explored their potential implications for patient outcomes. Methods: Seventy-eight patients with AF u...
Systolic time ratio measured by impedance cardiography accurately screens left ...
Nazário Leão, Rodrigo; Marques Silva, Pedro; Branco, Luísa; Fonseca, Helena; Bento, Bruno; Alves, Marta; Virella, Daniel; Palma Reis, RobertoBackground: The use of impedance cardiography (ICG) may play a role in the assessment of cardiac effects of hypertension (HT), especially its hemodynamic features. Hypertensive heart disease involves structural changes and alterations in left ventricular geometry that end up causing systolic and/or diastolic dysfunction. The IMPEDDANS study aims to assess the usefulness of ICG for the screening of left ventricu...
