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. 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

3. Isquemia silenciosa e arritmias ventriculares são preditores independentes de evenos no pós-infarto do miocárdio de baixo risco
pós-infarto agudo do miocárdio (IAM) têm mostrado baixo valor preditivo positivo quando estudados isoladamente. A possibilidade da Eletrocardiografia Dinâmica de 24 horas (ECGD) fornecer dados referentes a isquemia silenciosa (IS), arritmias ventriculares e modulação autonômica do coração pelo estudo da variabilidade da freqüência cardíaca (VFC),

4. Noninvasive prognostic markers for cardiac death and ventricular arrhythmia in long-term follow-up of subjects with chronic Chagas' disease
The objective of the present study was to investigate clinical, echocardiographic and electrocardiographic (12-lead resting ECG, 24-h ambulatory ECG monitoring and signal-averaged ECG (SAECG)) parameters in subjects with chronic Chagas' disease in a long-term follow-up as prognostic markers for adverse outcomes. Fifty adult outpatients (34 to 74 years old, 3

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. Cardiovascular changes in hypertensive patients undergoing dental treatment under local anesthesia with vasoconstrictors / Avaliação de parametros cardiovasculares em pacientes hipertensos submetidos a tratamento odontologico sob anestesia local com vasoconstritor
This double-blind crossover study evaluated cardiovascular parameters of twenty hypertensive patients under periodontal treatment with 3.6 ml of 2% lidocaine with 1:100,000 epinephrine or 3% prilocaine with 0.03UI/ml felypressin. Heart rate (HR), systolic (SBP), and diastolic (DBP) arterial blood pressures were recorded before, during and after the dental tr

7. Electrocardiographic and Blood Pressure Alterations During Electroconvulsive Therapy in Young Adults
OBJECTIVE - To study cardiovascular alterations in young patients with no apparent organic disease who underwent electroconvulsive therapy. METHODS - The study comprised 47 healthy patients (22 males and 25 females) with a mean age of 30.3 years, who underwent electroconvulsive therapy. Ambulatory blood pressure monitoring and continuous electrocardiographic

8. Electrocardiographic characteristics of neurocirculatory asthenia during everyday activities.
We describe the electrocardiographic changes during everyday activities recorded by ambulatory electrocardiographic monitoring in 67 patients with neurocirculatory asthenia. The findings were compared with the results of ambulatory monitoring in 33 healthy controls. We observed episodes of sinus tachycardia > 120/min unrelated to effort in 60 of the patients

10. Controlled study of 24-hour ambulatory electrocardiographic monitoring in patients with transient neurological symptoms.
Sixty unselected patients with transient neurological symptoms underwent 24-hour ambulatory electrocardiographic (ECG) monitoring. Haemodynamically significant arrhythmias were observed in 32% of patients, but in only 3% of an age- and sex-matched control group. Nine patients received specific anti-arrhythmic therapy, which resulted in marked symptomatic im
