  2. Rapid Interpretation of EKG's - Wikipedia

    en.wikipedia.org/wiki/Rapid_Interpretation_of_EKG's

    Rapid Interpretation of EKG's is a best-selling textbook for over 30 years [1] that teaches the basics of interpreting electrocardiograms. It adopts a simplistic fill-in-the-blank style [2] and is suited for medical students and junior residents. [1] The book was written by Dale Dubin, M.D., a plastic surgeon and convicted felon, [3] who has ...

  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. Signal-averaged electrocardiogram - Wikipedia

    en.wikipedia.org/wiki/Signal-averaged...

    Signal-averaged electrocardiography (SAECG) is a special electrocardiographic technique, in which multiple electric signals from the heart are averaged to remove interference and reveal small variations in the QRS complex, usually the so-called " late potentials ". These may represent a predisposition towards potentially dangerous ventricular ...

  5. Left axis deviation - Wikipedia

    en.wikipedia.org/wiki/Left_axis_deviation

    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. QRS complex - Wikipedia

    en.wikipedia.org/wiki/QRS_complex

    QRS complex. Schematic representation of a normal sinus rhythm ECG wave. 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).

  7. Automated ECG interpretation - Wikipedia

    en.wikipedia.org/wiki/Automated_ECG_interpretation

    Automated ECG interpretation. Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.

  8. Right axis deviation - Wikipedia

    en.wikipedia.org/wiki/Right_axis_deviation

    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 ...

  9. Dale Dubin - Wikipedia

    en.wikipedia.org/wiki/Dale_Dubin

    Dale Dubin (born 1940), is a former American plastic surgeon and author of several cardiology textbooks, though never practicing or being trained as a cardiologist. Dubin practiced medicine in Tampa, Florida, [1] and gained fame within the medical community with the 1972 publication of Rapid Interpretation of EKG's, a best-selling textbook ...
