The electrocardiogram is a recording of the electrical activity of the heart as it undergoes excitation (depolarization) and recovery (polarization) to initiate each beat of the heart. This electrical activity is represented by a tracing showing the various phases of the activity above or below ...
HEARTCRITERIAPOPULATIONCARDIOLOGYCONDUCTIONElectrocardiographic changes in athletes are common and usually reflect benign structural and electrical remodelling of the heart as a physiological adaptation to regular and sustained physical training (athlete's heart). The ability to identify an abnormality on the ...

The electrical system of the heart consists of the SA node (sinoatrial node), the AV node (atrioventricular node), and special tissues in the atria and the ventricles that conduct the current. The SA node is the heart's electrical pacemaker. It is a small patch of cells located in the ...

The ECG does not record all the heart's electrical activity. The electrodes placed on the surface of the body record only the currents that are transmitted to the area of electrode placement. Therefore there are actually “silent” electrical areas of the heart. For example, the ECG is not ...
the wave of depolarisation is normally towards the left due to the leftward orientation of the heart in the chest and the greater muscle mass of the left ventricle than the right. This overall direction of travel of the electrical depolarisation throug...
Single AV junctional echoes are inducible with ventricular stimulation in the majority of dogs and are a normal finding. Sustained AV junctional reentry is not inducible in the normal intact dog heart. 展开 关键词: dog AV node autonomic tone ...
