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. 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

3. Heart rate turbulence analysis in female patients with fibromyalgia
OBJECTIVE: Fibromyalgia is characterized by diffuse musculoskeletal pain and discomfort. There are several reports regarding autonomic nervous system dysfunction in patients with fibromyalgia. Heart rate turbulence is expressed as ventriculophasic sinus arrhythmia and has been considered to reflect cardiac autonomic activity. Heart rate turbulence has been

4. Maternal-fetal monitoring of patients with rheumatic heart disease during dental procedure under local anesthesia / Monitorização materno-fetal da portadora de doença valvar reumática durante procedimento odontológico sob anestesia local
During pregnancy, the organic systems of a woman are subjected to physiological modifications consequential to hormonal, anatomic and metabolical alterations. The most significant modification in the circulatory system is an increased cardiac output from the first three months of gestation. Women with heart disease may present with severe complications durin

5. Estudo de parâmetros eletrocardiográficos e de pressão arterial durante procedimento odontológico restaurador sob anestesia local com e sem vasoconstritor em portadores de doença arterial coronária / Investigation of electrocardiographic and blood pressure parameters during restorative dentistry procedure under local anesthesia with and without vasoconstrictor in coronary artery disease patients
Estudamos 62 pacientes, que com teste ergométrico positivo, manifestaram angina estável e estavam sob controle farmacológico. Todos apresentavam cinecoronariografia mostrando obstrução >70% em pelo menos uma das principais artérias coronárias. Objetivamos avaliar parâmetros eletrocardiográficos e de pressão arterial, durante procedimento odontológ

6. "Avaliação de pacientes assintomáticos com formas cardíacas iniciais da doença de Chagas, através da análise do eletrocardiograma dinâmico, ecocardiograma e peptídeo natriurético tipo B" / Evaluation of asymptomatic patients with initial cardiac forms of Chagas disease through the analysis of dynamic electrocardiography, echocardiography and Type-B natriuretic peptides
To evaluate clinical and evolutive features in patients with initial asymptomatic cardiac Chagas disease, a prospective study was carried out with 108 patients, age 18 and 50, at the Londrina State University Chagas disease outpatient clinic, from April to November 2002. Patients were submitted to: 1) clinical evaluation, 2) electrocardiography (EKG), 3) che

7. Effect of oral aminophylline in patients with angina and normal coronary arteriograms (cardiac syndrome X).
BACKGROUND: Patients with syndrome X (exertional angina, positive exercise test, normal coronary arteriogram) have an altered perception of cardiac pain. This symptom may arise from increased sensitivity to adenosine. Previous studies suggest that intravenous aminophylline (an adenosine receptor blocker) improves exercise tolerance in patients with this diso
