24,487 | Association of Left Ventricular Hypertrophy and Atrial Fibrillation with Hemorrhagic Evolution of Small Vessel Disease. | Cerebral small vessel disease (SVD) is often associated with hypertension and may evolve towards intracerebral hemorrhage (ICH) or lacunar ischemic stroke. However, the factors favoring the evolution towards ICH or lacunar stroke are not well understood.</AbstractText>This retrospective study included 326 consecutive p... |
24,488 | Newly acquired complete right bundle branch block early after heart transplantation is associated with lower survival. | Right bundle branch block (RBBB) after heart transplantation (HTX) is a common finding, but its impact on post-transplant survival remains uncertain. This study investigated the post-transplant outcomes of patients with complete RBBB (cRBBB) ≤ 30 days after HTX.</AbstractText>This registry study a... |
24,489 | Effects of Pacemaker Implantation on Sudden Cardiac Death Rate and Quality of Life in Atrial Fibrillation Patients With Ventricular Pauses. | Ventricular arrest is a rare arrhythmic disease in the clinic; 35% to 55% of cases are associated with atrial fibrillation (AF). It is well known that ventricular arrest for ≥3 seconds can lead to brain symptoms such as dizziness and even syncope, but it is not clear whether ventricular pauses (≥3 seconds... |
24,490 | Perimembranous ventricular septal defect closure via ultra-minimal trans intercostal incision in children. | This study aimed to investigate the safety, feasibility and, availability of perimembranous ventricular septal defect (PmVSD) closure via a left parasternal ultra-minimal trans intercostal incision in children.</AbstractText>From January 2015 to January 2019, 131 children with restrictive PmVSDs were enrolled in this s... |
24,491 | Coronary vasospasm as an etiology of recurrent ventricular fibrillation in the absence of coronary artery disease: a case report. | <b>Background:</b> Vasospastic angina (VA), or Prinzmetal's angina, is characterized by symptoms of coronary angina caused by coronary vasospasm, usually in the absence of atherosclerotic changes. It typically presents with chest pain, which can be accompanied by transient electrocardiographic changes, if visualized du... |
24,492 | Obstructive Sleep Apnea and Cardiovascular Disease. | Obstructive sleep apnea (OSA) presents as repetitive interruptions of ventilation >10 seconds during sleep as a result of upper airway obstruction resulting in increased respiratory effort. Intermittent hypoxia causes physiologic changes resulting in increased catecholamine production, increased total peri... |
24,493 | Lorenz Plot Analysis in Dogs with Sinus Rhythm and Tachyarrhythmias. | The Lorenz plot (LP), a graphical representation of heart rate variability, has been poorly studied in dogs to date. The present study aimed to describe the graphic features of LP in dogs with sinus rhythm (SR) and tachyarrhythmias, and to analyze the usefulness of its pattern recognition. One hundred and nineteen cani... |
