1. Comparison of Anxiety and Depression Symptoms in Individuals According to their Sex, Type of Cardiac Device, and Diagnosis of Chagas Disease
ABSTRACT Introduction: Implantable cardiac pacemakers or cardioverter defibrillators are alternatives for the treatment of arrhythmias, however, their use has caused changes in the emotional state of patients. The objective of this study was to compare the measures of anxiety and depression symptoms in individuals according to their sex, type of cardiac dev

2. ICD indication in hypertrophic cardiomyopathy: which algorithm to use?
SUMMARY OBJECTIVE: This study aimed to evaluate the agreement in the indication of implantable cardioverter-defibrillators in patients with Hypertrophic cardiomyopathy, as per the 2014 European Society of Cardiology and 2020 American Heart Association recommendations, and evaluate fragmented QRS as a predictor of cardiovascular outcome. METHODS: Retrospect

3. Update on Sports Participation for Athletes with Implantable Cardioverter Defibrillators
Abstract Prior statements have recommended restriction from competitive sports participation for all athletes with ICDs. Recent data, however, suggests that many athletes can participate in sports without adverse events. In the ICD Sports Registry, 440 athletes, aged 8-60 years, 77 of which were high-level interscholastic athletes, who had continued to pract

4. Unscheduled Emergency Visits after Cardiac Devices Implantation: Comparison between Cardioverter Defibrillators and Cardiac Resynchronization Therapy Devices in less than one year of Follow Up
Resumo Fundamento: O uso de dispositivos cardíacos eletrônicos implantáveis (DCEI) como o cardiodesfibrilador (CDI) e terapia de ressincronização cardíaca (TRC) - é cada vez maior. O número de eletrodos de estimulação e desfibrilação varia de acordo com o dispositivo. A colocação do eletrodo no ventrículo esquerdo aumenta o tempo cirúrgico p

5. Effectiveness of Implantation of Cardioverter-Defibrillators Therapy in Patients with Non-Ischemic Heart Failure: an Updated Systematic Review and Meta-Analysis
Abstract Objective: Implantable cardioverter-defibrillator has become the first-line therapy for prevention of sudden cardiac death. Controversial results still exist regarding the effectiveness of implantable cardioverter-defibrillator (ICD) in non-ischemic heart failure. Methods: The PubMed, Embase, and Cochrane Central databases were searched for random

6. Ventricular arrhythmias in Chagas disease
Sudden death is one of the most characteristic phenomena of Chagas disease, and approximately one-third of infected patients develop life-threatening heart disease, including malignant ventricular arrhythmias. Fibrotic lesions secondary to chronic cardiomyopathy produce arrhythmogenic substrates that lead to the appearance and maintenance of ventricular arrh

7. Efficacy of cognitive behavioral therapy in reducing psychiatric symptoms in patients with implantable cardioverter defibrillator: an integrative review
This article is a systematic review of the available literature on the benefits that cognitive behavioral therapy (CBT) offers patients with implanted cardioverter defibrillators (ICDs) and confirms its effectiveness. After receiving the device, some patients fear that it will malfunction, or they remain in a constant state of tension due to sudden electrica

8. Avaliação da fibrose miocárdica pela ressonância magnética e tomografia computadorizada com múltiplos detectores na cardiomiopatia hipertrófica / Myocardial fibrosis evaluation by magnetic resonance and multidetector computed tomography in hypertrophic cardiomyopathy
Hypertrophic cardiomyopathy (HCM) is a genetic cardiac disorder leading cause of sudden death in young people with extremely variable presentation, from asymptomatic to sudden death as first symptom, leads to challenging risk stratification. Recently, both cardiovascular magnetic resonance (CMR) and multidetector computed tomography (MDCT) were able to asses

9. Projeto, construção e testes de um desfibrilador multidirecional / Development and test of a multidirectional defibrillator
A fibrilação ventricular (FV) é um tipo de arritmia cardíaca com alto potencial letal, cujo único tratamento eficaz conhecido é a desfibrilação elétrica, ou seja, aplicação de choques de alta intensidade. Este procedimento, no entanto, pode causar sério comprometimento da função cardíaca por afetar deleteriamente as células miocárdicas, o qu

10. Analisador de desfibriladores e cardioversores. / Defibrillator and cardioverter analyzer.
A desfibrilação e a cardioversão elétricas são os procedimentos terapêuticos padrões para o tratamento, respectivamente, das arritmias de fibrilação e taquicardia ventricular. O funcionamento eficaz e seguro de desfibriladores e cardioversores requer uma manutenção preventiva e corretiva sendo, portanto, necessária uma avaliação freqüente do d

11. DECISION SUPPORT TO ELETROCARDIOGRAM VENTRICULAR FLUTTER AND FIBRILLATION DETECTION / APOIO À DECISÃO NA DETECÇÃO DE FLUTTER E FIBRILAÇÃO VENTRICULAR EM ELETROCARDIOGRAMA
Computer-based decision support is an important tool in business and management areas, being today essential for medical diagnosis. This dissertation presents a new electrocardiogram ventricular flutter and fibrillation detector algorithm, named DALUZ, and comparing its quality evaluation with seven other ventricular fibrillation detection algorithms. The ev

12. Mecanismos envolvidos na depressão contratil e lesão de miocitos cardiacos submetidos a campos eletricos de alta intensidade / Mechanics involved in in the depression contractile and injury of cardiac myocytes submitted to the high intensity electric fields
A desfibrilação é a única terapia conhecida para reverter o quadro de fibrilação ventricular. Entretanto, a estimulação do coração com campos elétricos de grande magnitude durante a desfibrilação pode lesar miócitos cardíacos, e, como conseqüência, a eficiência contrátil do coração ser reduzida. Neste trabalho, estudamos o efeito da esti
