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. Hipertrofia ventricular esquerda na hipertensão resistente : análise de aspectos eletrocardiográficos, vetorcardiográficos e ecocardiográficos / Left ventricular hypertrophy in resistant hypertension : analysis of electrocardiographic, vectorcardiographic and echocardiographic features
A hipertrofia ventricular esquerda caracterizada como lesão de órgão alvo aumenta o risco de morbi-mortalidade de 5 a 9 vezes quando presente. A detecção precoce da HVE permite a identificação de pacientes com risco, além de permitir a intervenção de forma precoce, melhorando o planejamento estratégico para o seu manejo. A hipertensão arterial re

5. Estudo do eletrocardiograma ambulatorial, eletrocardiograma de alta resolução (ECGAR) e variabilidade da frequência cardíaca como indicadores prognósticos na cardiomiopatia arritmogênica de cães Boxer / Study of ambulatory electrocardiography, signal-averaged electrocardiogram and heart rate variability as prognostic factors in Boxer dogs with arrhythmogenic cardiomyopathy
A cardiomiopatia arritmogênica do ventrículo direito (CAVD) é uma doença miocárdica genética e hereditária, com alta prevalência entre os cães da raça Boxer, causada por alterações nos genes que codificam os receptores de rianodina ou os desmossomos cardíacos. Caracteriza-se, histologicamente, por atrofia de miócitos do ventrículo direito, pri

6. 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

7. 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

8. Estudo das alterações da variabilidade da freqüência cardíaca e troponina no paciente séptico / Heart rate variability and troponin in septic patients
CONTEXTO: Estudos observacionais têm demonstrado alterações na variabilidade da freqüência cardíaca em pacientes em sepse, embora não exista publicação correlacionando lesão cardíaca causada pela inflamação sistêmica e redução da variabilidade da freqüência cardíaca. OBJETIVOS: Determinar, em pacientes em sepse, se a lesão cardíaca é ca

9. "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

10. The heart and tuberous sclerosis. An echocardiographic and electrocardiographic study.
Cross sectional echocardiography, 12 lead electrocardiography, and 24 hour ambulatory electrocardiography were performed in eleven patients with tuberous sclerosis. Echocardiography showed single or multiple intramyocardial masses, most commonly in the ventricular septum, suggestive of rhabdomyomata in seven of the eleven cases. One patient with a normal ech

11. Effect of Corwin (ICI 118587) on resting and exercise heart rate and exercise tolerance in digitalised patients with chronic atrial fibrillation.
The effect of Corwin, a new oral beta, partial agonist, on the ventricular response to atrial fibrillation was studied in digitalised patients during 24 hour ambulatory electrocardiography and during exercise on a treadmill in a double blind placebo controlled crossover trial. Corwin reduced the maximum heart rate during exercise from 162(16) beats/min to 12

12. The ST segment of the ambulatory electrocardiogram in a normal population.
The behaviour of the ST segment in everyday life was studied by ambulatory electrocardiography in 111 normal volunteers. Fifteen were excluded because of abnormal exercise responses (10 subjects) and significant postural ST segment shifts (five subjects). This left 62 men and 34 women, mean (SD) age 40.5 (12.6) years (range 20-67 years). Ambulatory monitorin
