  2. 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.

  3. Automated ECG interpretation - Wikipedia

    en.wikipedia.org/wiki/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.

  4. Rhythm interpretation - Wikipedia

    en.wikipedia.org/wiki/Rhythm_interpretation

    Rhythm interpretation is an important part of healthcare in Emergency Medical Services . Trained medical personnel can determine different treatment options based on the cardiac rhythm of a patient. There are many common heart rhythms that are part of a few different categories, sinus arrhythmia , atrial arrhythmia, ventricular arrhythmia .

  5. ST segment - Wikipedia

    en.wikipedia.org/wiki/ST_segment

    Schematic representation of normal ECG. In electrocardiography, the ST segment connects the QRS complex and the T wave and has a duration of 0.005 to 0.150 sec (5 to 150 ms). It starts at the J point (junction between the QRS complex and ST segment) and ends at the beginning of the T wave.

  6. Cardiac monitoring - Wikipedia

    en.wikipedia.org/wiki/Cardiac_monitoring

    Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram. [1]

  7. Electrocardiography in myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography_in...

    In spite of these limitations, the 12 lead ECG stands at the center of risk stratification for the patient with suspected acute myocardial infarction. Mistakes in interpretation are relatively common, and the failure to identify high risk features has a negative effect on the quality of patient care. [3]

  8. 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 ...

  9. ST elevation - Wikipedia

    en.wikipedia.org/wiki/ST_elevation

    An ST elevation is considered significant if the vertical distance inside the ECG trace and the baseline at a point 0.04 seconds after the J-point is at least 0.1 mV (usually representing 1 mm or 1 small square) in a limb lead or 0.2 mV (2 mm or 2 small squares) in a precordial lead. [2] The baseline is either the PR interval or the TP interval ...
