چکیده
II and III, I and II, I and aVF, aVL and aVF, and from a vectorial combination of leads I, II, and III. The group means were similar, but there were large intraindividual differences of the QRS axis (up to ±350) and, to a somewhat lesser degree, of the T axis between the different lead combinations. Hypothetically, the axes from different lead combinations should be identical. The intraindividual discrepancies of the mean frontal plane vectors were also large (about 20%). In a smaller sample of 50 healthy

Similarly, in Figure 1 C, the angle of 1 I .2” is added to 90” (lead aVF, largest net QRS defection) since the net QRS deflection in lead I is negative. Rapid calculation of the electrocardiographic frontal axis is desirable. The method described is ...
متن کاملReliability and accuracy in three-dimensional gait analysis: a comparison of two lower body protocols.
The standard Plug-in-Gait (PiG) protocol used in three-dimensional gait analysis is prone to errors arising from inconsistent anatomical landmark identification and knee axis malalignment. The purpose of this study was to estimate the reliability and accuracy of a custom made lower body protocol (MA) compared with the PiG protocol. Twenty-five subjects volunteered to evaluate the intertrial rel...
متن کاملReliability and measurement error of frontal and horizontal 3D spinal motion parameters in 219 patients with chronic low back pain
BACKGROUND In order for measurements to be clinically useful, data on psychometric conditions such as reliability should be available in the population for which the measurements are intended to be used. This study comprises a test-retest design separated by 7 to 14 days, and evaluates the intra and interrater reliability of regional frontal and horizontal spinal motion in 219 chronic LBP patie...
متن کاملModified limb lead ECG system effects on electrocardiographic wave amplitudes and frontal plane axis in sinus rhythm subjects
OBJECTIVE Modified Limb Lead (MLL) ECG system may be used during rest or exercise ECG, or atrial activity enhancement. Because of modification in the limb electrode placement, changes are likely to happen in ECG wave amplitudes and frontal plane axis, which may alter the clinical limits of normality and ECG diagnostic criteria. The present study investigated the effects of the modified limb ele...
متن کاملAn accurate method of radiological assessment of acetabular volume and orientation in computed tomography spatial reconstruction
BACKGROUND Two-dimensional (2D) measurements of acetabular morphology and orientation are well known; there is less information on these acetabular characteristics in three dimensions. One important reason is the lack of standardized reference planes for the pelvis, especially in relation to the spinopelvic unit; another is that no method precisely assesses the acetabulum in three-dimensional (...
