  2. 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°.

  3. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [5] using electrodes placed on the skin.

  4. Cardiac aberrancy - Wikipedia

    en.wikipedia.org/wiki/Cardiac_aberrancy

    Cardiac aberrancy is a type of disruption in the shape of the electrocardiogram signal, representing abnormal activation of the ventricular heart muscle via the electrical conduction system of the heart. Normal activation utilizes the bundle of His and Purkinje fibers to produce a narrow (QRS) electrical signal.

    A resting electrocardiogram (EKG) is an early step in the diagnostic process. [11] An electrocardiogram (EKG) involves the use of electrodes that are placed on the arms, chest, and legs. [29] These sensors detect any abnormal rhythms that the heart may be producing. This test is painless and it helps detect insufficient blood flow to the heart ...
