  2. Electrocardiography in myocardial infarction - Wikipedia

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

    The 2018 European Society of Cardiology/American College of Cardiology Foundation/American Heart Association/World Health Federation Universal Definition of Myocardial Infarction for the ECG diagnosis of the ST segment elevation type of acute myocardial infarction require new ST elevation at J point of at least 1mm (0.1 mV) in two contiguous leads with the cut-points: ≥1 mm in all leads ...

  3. Diagnosis of myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_myocardial...

    12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1-V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. The primary purpose of the electrocardiogram is to detect ischemia or acute coronary injury in broad, symptomatic emergency department populations.

  4. Myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Myocardial_infarction

    A 12-lead ECG showing an inferior STEMI due to reduced perfusion through the right coronary artery. Elevation of the ST segment can be seen in leads II, III and aVF. Electrocardiograms (ECGs) are a series of leads placed on a person's chest that measure electrical activity associated with contraction of the heart muscle. [87]

  5. ST elevation - Wikipedia

    en.wikipedia.org/wiki/ST_elevation

    12-lead electrocardiogram showing ST-segment elevation (orange) in I, aVL and V1–V5 with reciprocal changes (blue) in the inferior leads, indicative of an anterior wall myocardial infarction. When there is a blockage of the coronary artery, there will be lack of oxygen supply to all three layers of cardiac muscle (transmural ischemia).

  6. Third-degree atrioventricular block - Wikipedia

    en.wikipedia.org/wiki/Third-degree_atrio...

    Since pacemaker correction of the third-degree block requires full-time pacing of the ventricles, a potential side effect is pacemaker syndrome, and may necessitate the use of a biventricular pacemaker, which has an additional 3rd lead placed in a vein in the left ventricle, providing more coordinated pacing of both ventricles.

  7. Sgarbossa's criteria - Wikipedia

    en.wikipedia.org/wiki/Sgarbossa's_criteria

    at least one lead with concordant STE (Sgarbossa criterion 1) or at least one lead of V1-V3 with concordant ST depression (Sgarbossa criterion 2) or proportionally excessively discordant ST elevation in V1-V4, as defined by an ST/S ratio of equal to or more than 0.20 and at least 2 mm of STE.

    Bracket, top 12 teams, snubs from final CFP rankings The four at-large teams that have received first-round games are No. 3 Notre Dame, No. 4 Texas, No. 5 Penn State and No. 7 Ohio State.

  9. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Diagram showing the contiguous leads in the same color in the standard 12-lead layout. Each of the 12 ECG leads records the electrical activity of the heart from a different angle, and therefore align with different anatomical areas of the heart. Two leads that look at neighboring anatomical areas are said to be contiguous. [43]
