1. O que é a Síndrome de Wolff-Parkinson-White?
A síndrome de Wolff-Parkinson-White (WPW) é uma doença congênita gerando taquicardias e arritmias, que reduzem a eficiência do coração. As manifestações clínicas incluem sudorese, dor no peito, cefaleia, dificuldades respiratórias, letargia, sensação de desmaio, perda de apetite, palpitações rápidas e visíveis no tórax, incluindo insufic

2. Bradycardia in a pediatric population after sugammadex administration: case series
Abstract Sugammadex is a distinctive neuromuscular reversal drug that acts by encapsulating the neuromuscular relaxant molecule and dislodging it from its site of action. Sugammadex has been approved for pediatric patients over 2 years of age. Although arrhythmias have been reported, there is no report of adverse effects in healthy children, such as severe b

3. 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

4. Relationship between ventricular repolarization parameters and the inducibility of ventricular arrhythmias during electrophysiological study in patients with coronary artery disease
SUMMARY OBJECTIVE: Risk stratification of sudden cardiac death in patients with coronary artery disease is of great importance. We evaluated the association between ventricular repolarization and induction of malignant ventricular arrhythmias on electrophysiological study of patients with coronary artery disease. METHODS AND RESULTS: A total of 177 patient

5. Dysautonomia Evaluation by Holter in Chagas Heart Disease
Abstract Background Sudden cardiac death is the main lethal mechanism associated with Chagas cardiomyopathy. Studies suggest that dysautonomia may represent a relevant, intense, independent, and early phenomenon in the natural history of the disease, even when ventricular systolic function is preserved, and may also be the mechanism that triggers malignant

6. Treatment of Hepatitis C with Direct-Acting Antivirals does not Induce Significant Arrhythmias
Abstract Background Chronic Hepatitis C (CHC) therapy with direct-acting antivirals (DAAs) has high efficacy and safety, but some cases of bradyarrhythmias have been described. Objective To evaluate heart rhythm disorders during DAA treatments. Methods Forty-eight patients with CHC (mean 61 years of age; 56% males; 73% HCV genotype 1) were evaluated be

7. 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

8. Short-Term Results of Ivabradine versus Metoprolol: The Effects on Atrial Fibrillation in Patients Undergoing Off-Pump Coronary Artery Bypass Grafting
ABSTRACT Introduction: Classic coronary artery bypass grafting (CABG) surgery involves diastolic cardiac arrest under cardiopulmonary bypass, while off-pump CABG (OPCABG) has become widespread in recent years. Methods: 174 patients who underwent OPCABG were included in the study. Patients were divided into two groups. Group I (n=90) received ivabradine and

9. Comparison between Bruce and Ramp Protocols for Exercise Testing in the Diagnosis of Myocardial Ischemia
Abstract Background: Exercise tests are an important tool in the investigation of myocardial ischemia. The ramp protocol has gained increasing importance in clinical practice because of the possibility of individualizing its exercise intensity. Objective: To assess and compare the sensitivity, specificity, and accuracy of Bruce and ramp protocols for exerc

10. Successful Surgical Treatment of Coronary Aneurysm, Ascending Aortic Aneurysm, and Bicuspid Aorta for a Kawasaki Disease Patient
Abstract Kawasaki disease was first reported in 1967, and it was classified as an autoimmune vasculitis of the small and medium arteries. It is a self-limiting condition that occurs mostly in childhood, but it may involve complications — such as coronary artery aneurysms, myocardial ischemia, and arrhythmias — with significant morbidity and mortality tha

11. The Role of the Immune System on the Cardiac Complications Observed in SARS-CoV-2
Abstract An acute respiratory syndrome caused by SARS-CoV2 was declared a pandemic by the World Health Organization. Current data in the world and in Brazil show that approximately 40% of patients who died have some type of cardiac comorbidity. There are also robust reports showing an increase in IL-6 / IL-1B / TNF-alpha and the presence of lymphopenia in pa

12. Heart rate turbulence assessed through ergometry after myocardial infarction: a feasibility study
ABSTRACT BACKGROUND: Coronary artery disease is an important cause of morbidity and mortality. The impact of ventricular arrhythmias with impaired cardiac vagal activity is one of the most recently studied prognostic factors. However, there are no studies evaluating the phenomenon of heart rate turbulence (HRT) during physical exertion. OBJECTIVE: To stu
