Evidence that the degree of obstructive sleep apnea may not increase myocardial ischemia and arrhythmias in patients with stable coronary artery disease
(Faculdade de Medicina / USP, 2009)
There is controversy regarding whether obstructive sleep apnea is responsible for triggering myocardial ischemia, arrhythmias and heart rate variability in patients with coronary artery disease. OBJETIVE: The objective of ...
Reversible redox modifications of ryanodine receptor ameliorate ventricular arrhythmias in the ischemic-reperfused heart
(American Physiological Society, 2016)
Previous results from our laboratory showed that phosphorylation of ryanodine receptor 2 (RyR2) by Ca2+ calmodulin-dependent kinase II (CaMKII) was a critical but not the unique event responsible for the production of ...
A study of effectiveness of midazolam sedation for prevention of myocardial arrhythmias in endosseous implant placement
Purpose: The study aimed to assess electrocardiographic alterations during oral implant placement surgeries under local anesthesia (lidocaine chlorhydrate with epinephrine), using 15 mg of midazolam as an anxiolytic ...
Polymorphism, coupling interval and prematurity index in dogs with degenerative mitral valve disease and ventricular arrhythmias
Ventricular arrhythmias (VA) are a recognized concern in dogs with degenerative mitral valve disease (DMVD). The coupling interval (CI) and the prematurity index (PI) have been shown to accurately differentiate between ...
ACAO ANTIARRITMICA DA METOCLOPRAMIDA (PLASIL®) EM INTOXICACAO DIGITALICA EXPERIMENTAL. COMPARACAO COM A DIFENIL-HIDANTOINA
The antiarrhythmic action of metoclopramide in cardiac arrhythmias caused by toxic doses of desacetyl-lanatoside C and digitoxin was studied in dogs. A comparison was made between the efficacy of metoclopramide and ...
The effects of atropine and methotrimeprazine on the epinephrine-induced arrhythmias in halothane-anesthetized dogs
(Canadian Vet Med Assoc, 2001-04-01)
The effects of atropine and methotrimeprazine on epinephrine-induced ventricular arrhythmias were evaluated in halothane-anesthetized dogs. Ten mixed-breed dogs were assigned to 3 treatments (saline, atropine, and ...
Role of acetylcholine in electrical stimulation-induced arrhythmia in rat isolated atria
(Lippincott Williams & WilkinsPhiladelphiaEUA, 1999)
ECG arrhythmia classification based on optimum-path forest
An important tool for the heart disease diagnosis is the analysis of electrocardiogram (ECG) signals, since the non-invasive nature and simplicity of the ECG exam. According to the application, ECG data analysis consists ...
Granulocyte Colony-stimulating Factor Reduces Mortality by Suppressing Ventricular Arrhythmias in Acute Phase of Myocardial Infarction in Rats
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Our aim was to evaluate the effects of granulocyte colony-stimulating factor (G-CSF) on early cardiac arrhythmias after myocardial infarction (MI) and the impact on survival. Male Wistar rats received repeated doses of 50 ...
