Cardiac Mean Electrical Axis in Thoroughbreds—Standardization by the Dubois Lead Positioning System
BACKGROUND Different methodologies for electrocardiographic acquisition in horses have been used since the first ECG recordings in equines were reported early in the last century. This study aimed to determine the best ECG electrodes positioning method and the most reliable calculation of mean cardiac axis (MEA) in equines. MATERIALS AND METHODS We evaluated the electrocardiographic profile o...
متن کاملComparison of Dubois and Base - Apex Lead Methods to Calculate QRS Angle ( Mean Electrical Axis ) in Thoroughbreds
This study evaluated electrocardiographic profile of 53 Thoroughbreds, clinically healthy, with ages ranging 2-7 years old, 38 males and 15 females, all reared at the São Paulo Jockey Club, Brazil. Two electrocardiograms were recorded in each horse, and the results of mean electrical axis in frontal plane, obtained by measuring QRS complexes amplitude, were compared using two electrode position...
متن کاملEffects of tramadol on electrocardiogram, mean electrical axis and respiration in Kagani goats (Capra hircus)
The effects of tramadol on electrocardiogram (ECG), mean electrical axis and respiratory rates were studied in adult kagani goats after intramuscular administration of tramadol at 1 mg/kg b.wt. as a prelude to its clinical use as an analgesic in veterinary practice. The ECG was monitored by standard bipolar leads and discernible electrocardiographic features were observed in lead II. The normal...
متن کاملThe Relationship between Electrical Axis by 12-Lead ECG and Anatomical Axis of the Heart by CMR in Healthy Subjects Short title: Electrical vs anatomical heart axis
Background: The traditional assumption has been that there is a close relationship between the electrical and anatomical axes of the heart. The aim of this study was to test the hypothesis that there is a correlation between the electrical and anatomical axes of the heart, in both the frontal and transverse planes, in healthy subjects. Methods: Ninety-four healthy volunteers (48 males, 46 femal...
متن کاملECG interpretation part 1: Understanding mean electrical axis.
The ability to determine electrical axis is important to detect subtle early warning signs of a change in the patient’s cardiovascular condition. Abnormal or altered conduction patterns may occur as a result of changed physical conditions (e.g., increased ascites), conduction disturbances (e.g., bundle branch or fascicular blocks), or biochemical imbalances (e.g., hyperkalemia). Furthermore, de...
