Challenges in diagnosis and management of spontaneous coronary artery dissection in a young patient

Abstract Spontaneous coronary artery dissection (SCAD) is characterized by tear of the inner layer in the coronary artery, creating a false lumen between the inner and central layer. Its infrequent incidence often leads to delay in diagnosis posing challenges in management. There are currently no guideli...

QT dispersion changes after transcatheter aortic valve implantation in patients with aortic stenosis

Abstract Objective: The aim of this study was to evaluate the QT dispersion and echocardiographic parameters in patients before and after transcatheter aortic valve implantation (TAVI). Methods: One hundred and fifty-two patients with severe aortic valve stenosis (AS) were included in our study. Ninety...

Chest radiography: Demonstrates cardiomegaly and prominent pulmonary vascular markings. Electrocardiography: Shows right ventricular hyper...

Retrospective study of allometric relationship between heart rate, electrocardiographic parameters and bodyweight in dogs

The allometric relationship between bodyweight (BW) and heart rate (HR) has been described as inversely proportional in domestic species, but that has been refuted. The relationship between HR and electrocardiographic variables is described in literature. However, studies about the variation and influenc...

Bradycardic and Antiarrhythmic Effects of the D-Limonene in Rats
