  2. Hexaxial reference system - Wikipedia

    en.wikipedia.org/wiki/Hexaxial_reference_system

    The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. The hexaxial reference system, better known as the Cabrera system, is a convention to present the extremity leads of the 12 lead electrocardiogram, [1] that provides an illustrative logical sequence that helps interpretation of the ECG, especially to determine the heart's ...

  3. Anatomical plane - Wikipedia

    en.wikipedia.org/wiki/Anatomical_plane

    When describing anatomical motion, these planes describe the axis along which an action is performed. So by moving through the transverse plane, movement travels from head to toe. For example, if a person jumped directly up and then down, their body would be moving through the transverse plane in the coronal and sagittal planes.

  4. QRS complex - Wikipedia

    en.wikipedia.org/wiki/QRS_complex

    Diagram showing how the polarity of the QRS complex in leads I, II, and III can be used to estimate the heart's electrical axis in the frontal plane. The QRS complex is the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG or EKG). It is usually the central and most visually obvious part of the tracing.

  5. Left axis deviation - Wikipedia

    en.wikipedia.org/wiki/Left_axis_deviation

    The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane.. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.

  6. Coronal plane - Wikipedia

    en.wikipedia.org/wiki/Coronal_plane

    The coronal plane is an example of a longitudinal plane.For a human, the mid-coronal plane would transect a standing body into two halves (front and back, or anterior and posterior) in an imaginary line that cuts through both shoulders.

  7. Coronary arteries - Wikipedia

    en.wikipedia.org/wiki/Coronary_arteries

    Coronary artery disease (CAD) or ischemic heart disease are the terms used to describe narrowing of the coronary arteries. [8] As the disease progresses, plaque buildup can partially block blood flow to the heart muscle. Without enough blood supply , the heart is unable to work properly, especially under increased stress.

  8. List of human anatomical regions - Wikipedia

    en.wikipedia.org/wiki/List_of_human_anatomical...

    the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side) of hips; the pubic region encompassing the area above the genitals. The pelvis and legs contain, from superior to inferior, the inguinal or groin region between the thigh and the abdomen,

  9. Sagittal plane - Wikipedia

    en.wikipedia.org/wiki/Sagittal_plane

    Coronal axis, medial-lateral axis, or frontal axis is the axis perpendicular to the sagittal plane, i.e., the one formed by the intersection of the coronal and the transversal planes. [8] Extension and flexion are the movements of limbs within the sagittal plane. [9] Abduction and adduction are terms for movements of limbs within the coronal ...
