    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°.

  4. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    The electrical axis of the heart is the net direction in which the wave of depolarization travels. It is measured using an electrocardiogram (ECG). Normally, this begins at the sinoatrial node (SA node); from here the wave of depolarisation travels down to the apex of the heart. The hexaxial reference system can be used to visualise the ...

    en.wikipedia.org/wiki/Language_acquisition_device

    The Language Acquisition Device (LAD) is a claim from language acquisition research proposed by Noam Chomsky in the 1960s. [1] The LAD concept is a purported instinctive mental capacity which enables an infant to acquire and produce language. It is a component of the nativist theory of language. This theory asserts that humans are born with the ...
