1. The relationship between premature ventricular complexes and index of cardiac-electrophysiological balance
SUMMARY OBJECTIVE: Premature ventricular complexes are common in healthy individuals’ ambulatory monitoring. The index of cardiac-electrophysiological balance may predict malignant ventricular arrhythmias. This study investigated the relation between Premature ventricular complex burden and index of cardiac-electrophysiological balance in 24-h Holter moni

2. Association between ventricular premature contraction burden and ventricular repolarization duration
SUMMARY OBJECTIVE: Premature ventricular contraction is generally known as benign in the absence of structural heart disease; however, premature ventricular contraction-induced left ventricular systolic dysfunction or ventricular arrhythmias are defined in some cases. Ventricular repolarization duration differs between myocardial cells, which causes myocard

3. Scanning of paroxysmal atrial fibrillation as an etiological risk factor in patients with acute ischemic stroke: prospective study
Abstract BACKGROUND: Prevention of recurrence of stroke depends on recognition of the underlying mechanism of ischemia. OBJECTIVE: To screen patients who were hospitalized with diagnosis of acute ischemic stroke in terms of atrial fibrillation (AF) with repeated Holter electrocardiography recordings. DESIGN AND SETTING: Prospective study conducted at Kony

4. Smartphone-Based Screening for Cardiovascular Diseases: A Trend?
Abstract Cardiovascular diseases are the leading cause of death in the world. People living in vulnerable and poor places such as slums, rural areas and remote locations have difficulty in accessing medical care and diagnostic tests. In addition, given the COVID-19 pandemic, we are witnessing an increase in the use of telemedicine and non-invasive tools for

5. Abnormalities of Cardiac Situs and Heart Disease Diagnosed by Echocardiography in Patients with Biliary Atresia
Abstract Background: Left isomerism (LI) is a common finding in patients with biliary atresia (BA), and it can be identified by echocardiography. Several comorbidities may be present in patients with LI, including heart disease. Objective: To investigate the prevalence of LI and heart disease in children (< 18 years of age) with BA followed-up at Hospital

6. Evaluation of cardiac-electrophysiological balance according to National Institutes of Health Stroke Scale score at admission and discharge in acute ischemic stroke patients: A pilot study
SUMMARY OBJECTIVE: The main objectives of this investigation were to determine whether there were any relationships between corrected cardiac-electrophysiological balance value and National Institutes of Health Stroke Scale scores at admission and discharge in patients with acute ischemic stroke and to assess whether cardiac-electrophysiological balance val

7. Is there a relation between computed tomography findings and electrocardiography findings in COVID-19?
SUMMARY OBJECTIVE: COVID-19 can cause lung damage and may present with pneumonia in patients. In the present study, the correlation between the severity of pneumonia and electrocardiography parameters of COVID-19 were examined. METHODS: A total of 93 COVID-19 patients and a control group consisting of 62 volunteers were studied. Computed thorax tomography

10. Electrocardiographic Abnormalities in Hypertension Models
Abstract Background: Hypertensive condition can lead to abnormalities in heart structure and electrical activity. The electrocardiogram (ECG) is a recording of the electrical activity of the heart and widely used to diagnose and detect heart problem. Objective: We conducted a comparative ECG analysis between two hypertension models (L-NAME and SHR) and the

11. Epidemiological features, echocardiographic findings, and parasite load in patients with Chagas disease
Abstract INTRODUCTION Chagas disease is a major public health problem that is endemic in Brazil and Latin America. This study aimed to determine the socioeconomic, demographic, and clinical characteristics of 171 patients (mean age, 45 years; female, 65%) with Chagas disease at Hospital Universitário de Brasília, Federal District, Brazil. METHODS We im

12. Robotic Mitral Valve Surgey Combined with Left Atrial Reduction and Ablation Procedures
Abstract Introduction: This study aimed to evaluate the feasibility and efficacy of robotically assisted, minimally invasive mitral valve surgery combined with left atrial reduction for mitral valve surgery and elimination of atrial fibrillation (AF). Methods: Eleven patients with severe mitral regurgitation, AF, and left atrial enlargement who underwent r
