The leads selection for Tpeak-Tend interval measurement in electrocardiogram

The normal electrocardiograms (ECGs) from 24 leads, including standard limb leads, augmented unipolar limb leads, unipolar chest leads and apex base lead (A B), of 90 healthy police dogs were traced and analysed.

Based on parallel conductance between laminated shale and dispersed shaly sands, and the assumption under which dispersed shaly sands are described with dual water conductivity model, a new dual water conductivity model for laminated and dispersed shaly sands is established.

Value of ST segment elevation of aVR lead in patients with acute anterior wall myocardial infarction.;

Analysis of clinical data about ST segment elevation of aVR lead in patients with acute anterior wall myocardial infarction

Comparison of head-chest lead and routine lead electrocardiograms in human right ventricular pacing;

Diagnostic significance of Head-chest lead electrocardiogram on Q wave in lead Ⅲ of conventional electrocardiogram;

Comparison of normal ECGs between limb lead and corresponding head-chest lead in healthy subjects;

Low voltage of aVF lead predicting the number of severely narrowed coronary arteries;

Objective To compare ECGS from standard limb-lead system with ECGS from Mason-Likar modified limb-lead system in normal subjects.

Firstly, the lead systems for ECG sampling are introduced, simply on the relation of every lead.
