  • Cardiac
  • These effects are not explained by conventional ECG theory but they do explain why body surface ST depression does not localise cardiac ischaemia in humans. (edu.au)
  • cardiac
  • Finally we analyze the components of an EST and potential sensitivities, significances and predictability of the changes in the outcome data that will provide diagnosis overt cardiovascular disease, and for purposes of exercise prescription and evaluation of rehabilitation effects in cardiac patients. (oatext.com)
  • In addition, EST is often used to evaluate the effects of pharmacological medication on whole body function, and for exercise prescription in diseases and conditions that include but are limited to cardiac rehabilitation, obesity, diabetes and various neuropathies. (oatext.com)
  • Arrhythmias
  • Non-dipolar distribution of Int-QRST maps, more pronounced in diabetic patients with depression, can be a specific indicator of the increased risk of severe ventricular arrhythmias occurring prior to abnormalities detectable on the standard 12-lead ECG recordings, which is of great importance especially in prevention of life-threatening arrhythmias. (nel.edu)
  • This review will highlight the basic principles and recent advantages of MCGs, and the application of MCG in clinical diagnosis, especially in cases whose ECGs are non-diagnostic or not specific, such as detecting baseline shift in ischemic heart disease, noninvasive His potential recording, detection of arrhythmic mechanism defining reentrant circuits vs non reentrant mechanism, diagnosis of fetal arrhythmias and prolongation of QT interval.

  • isointegral
  • For this purpose, analysis of the relationship between the Int-QRST (isointegral) maps distribution and the depressive symptoms intensification, as well interrelation between depressive and diabetic symptoms were performed. (nel.edu)
  • Isointegral QRST maps turned out to display abnormal, i.e. non-dipolar distribution. (nel.edu)
  • parameters
  • The potential usefulness of the method may be improved by increasing the depth of light penetration, confirming its accuracy against other methods evaluating cerebral flow cessation, and developing absolute parameters for cerebral perfusion. (diva-portal.org)
  • CONCLUSIONS
  • CONCLUSIONS: AF associated with consistent atrial activation sequences after prior ablation emanates mostly from localized sources that can be mapped and ablated. (biomedsearch.com)
  • chest
  • In a conventional 12-lead ECG, ten electrodes are placed on the patient's limbs and on the surface of the chest. (wikipedia.org)
  • The vast majority of electrocardiograms are recorded by placing electrodes on various sites on the body surface, typically the limbs and the chest . (everything2.com)
  • RESULTS
  • The method's potential is illustrated not only by modeling results but also by estimation of an arbitrary slice from the parameterized model. (utah.edu)
  • patient
  • One VT per patient was mapped (CL 348 +/- 102.1 ms). Diastolic potentials were recorded from all (77.7 +/- 43.8 ms pre-QRS onset) and concealed entrainment demonstrated in 3. (biomedsearch.com)
  • normal
  • Corresponding discriminant maps were also computed for each pairwise comparison (AMI versus N, IMI versus N, and PMI versus N) by subtracting the normal group mean voltages from each MI group mean voltages and by further dividing each resulting difference by the composite standard deviation calculated from the pooled groups.

  • patients
  • Assessment of body surface potential mapping in diabetic patients with recognized depression. (nel.edu)
  • Moreover, extent of Int-QRST maps multipolarity increased in the examined diabetic patients along with DM II duration, BDI scores and HbA1c level. (nel.edu)
  • During AF with a cycle length of 211+/-32 ms, activation mapping identified 1 to 3 sources at the origin of atrial wavefronts in 38 patients (76%) predominantly in the left atrium, including the coronary sinus region. (biomedsearch.com)
  • model
  • First, an efficient forward model is proposed, coupling the Mitchell-Schaeffer transmembrane potential model with a current dipole formulation. (embs.org)
  • signals
  • The advantages of MCG over traditional electrocardiograms (ECGs) are increased sensitivity to small signals and lack of conductivity in body tissues, presentation of direct component signals and primary currents. (biomedsearch.com)
