The axis of the ECG is the major direction of the overall electrical activity of the heart. It can be normal, leftward (left axis deviation, or LAD), rightward (right axis deviation, or RAD) or ...

Determine Axis on the ECG. The axis on the ECG can give a clue to many different pathologic states. ... looking at 12-lead ECG tracings, studying ECGs for the cardiology boards, ...

After 100 years, the 12-lead electrocardiogram (ECG) remains the most accessible and inexpensive noninvasive diagnostic and prognostic tool in cardiology. Almost every hospitalized patient will ...

1. Read the ECG print out. The ECG interpretive software is usually very accurate at working out the QRS axis – if it’s less than -30 degrees it’s left axis deviation and if it’s more than +90 degrees ...

The axis is normal between 0° and +90° (positive QRS complex in leads I and aVF). T waves that are tall and, most importantly, symmetric in leads V2-V5 (┴) are noted.

Intensive athletic conditioning is associated with morphological cardiac changes, including increased cavity dimensions, wall thickness and ventricular mass, which are reflected on the 12-lead ECG.1 2 ...

With cutting edge 12-lead ECG based on 3D vector ECG technology built into a smartwatch, HeartBeam’s latest patent further expands on the Company’s anytime, anywhere capabilities.
