Electrocardiographic Preexcitation and Risk of Cardiovascular Morbidity and Mortality
The Wolf–Parkinson–White (WPW) syndrome is a clinical entity characterized by the presence of ≥1 accessory pathways between the atria and the ventricles pre-disposing patients to arrhythmias. Anterograde conduction through the accessory pathway leads to preexcitation of the ventricles and a delta wave in the ECG. The prevalence of preexcitation in the general population has been estimated to be...
متن کاملHistorical notes and classification of the variants of ventricular preexcitation
Almost 25 years ago, Gallagher et al. [1] stated that “the role of Mahaim fibers in the genesis of cardiac arrhythmias in man has been controversial since they were first described.’’The original description of these fibers was made by Ivan Mahaim in the late 1930s [2, 3] (Fig. 1.1). He found a conducting tissue extending from the atrioventricular (AV) node to the ventricular myocardium. There ...
متن کاملElectrocardiographic and Hemodynamic Changes
To investigate the electrocardiographic and hemodynamic changes in isolated right ventricular infarction, 0.25 ml or 0.5 ml of metallic mercury was injected into the right coronary artery of 14 closedchest dogs. At autopsy, at least 60% of the right ventricle was necrotic in every dog. Heniodynamic observations were made in 11 and electrocardiographic mapping was performed in all 14 dogs. Right...
متن کاملElectrocardiographic Preexcitation and Risk of Cardiovascular Morbidity and Mortality: Results From the Copenhagen ECG Study.
BACKGROUND The majority of available data on the clinical course of patients with ventricular preexcitation in the ECG originates from tertiary centers. We aimed to investigate long-term outcomes in individuals from a primary care population with electrocardiographic preexcitation. METHODS AND RESULTS Digital ECGs from 328 638 primary care patients were collected during 2001 to 2011. We ident...
متن کاملAge-dependent electrocardiographic and echocardiographic changes in German Shepherd dogs
By causing numerous changes in the cardiovascular system, ageing leads to a decreased threshold for clinical manifestation of heart disease. The aim of this study was to define the existence of cardiac structural and functional changes in healthy dogs of different age. Radiographic, electrocardiographic (ECG) and echocardiographic examinations of 20 clinically healthy German Shepherd dogs were ...
