  2. Electrocardiography - Wikipedia

    en.wikipedia.org/wiki/Electrocardiography

    Frames 24–28 in the animation depict repolarization of the ventricles. The epicardium is the first layer of the ventricles to repolarize, followed by the myocardium. The endocardium is the last layer to repolarize. The plateau phase of depolarization has been shown to last longer in endocardial cells than in epicardial cells.

  3. Endocardium - Wikipedia

    en.wikipedia.org/wiki/Endocardium

    The endocardium underlies the much more voluminous myocardium, the muscular tissue responsible for the contraction of the heart. The outer layer of the heart is termed epicardium and the heart is surrounded by a small amount of fluid enclosed by a fibrous sac called the pericardium. [2]

  4. Cardiac conduction system - Wikipedia

    en.wikipedia.org/wiki/Cardiac_conduction_system

    [2] The conduction system consists of specialized heart muscle cells, situated within the myocardium. [3] There is a skeleton of fibrous tissue that surrounds the conduction system which can be seen on an ECG. Dysfunction of the conduction system can cause irregular heart rhythms including rhythms that are too fast or too slow.

  5. Cardiology diagnostic tests and procedures - Wikipedia

    A variety of blood tests are available for analyzing cholesterol transport behavior, HDL, LDL, triglycerides, lipoprotein little a, homocysteine, C-reactive protein, blood sugar control: fasting, after eating or averages using glycated albumen or hemoglobin, myoglobin, creatine kinase, troponin, brain-type natriuretic peptide, etc. to assess the evolution of coronary artery disease and ...

  6. Cardiac muscle - Wikipedia

    en.wikipedia.org/wiki/Cardiac_muscle

    The inner endocardium lines the cardiac chambers, covers the cardiac valves, and joins with the endothelium that lines the blood vessels that connect to the heart. On the outer aspect of the myocardium is the epicardium which forms part of the pericardial sac that surrounds, protects, and lubricates the heart. [1]

  7. Intrinsicoid deflection - Wikipedia

    en.wikipedia.org/wiki/Intrinsicoid_deflection

    In the electrocardiogram, the intrinsicoid deflection is the downstroke of the QRS complex, from its highest amplitude until it reaches the baseline or lower. [1] Since the ventricles normally depolarize from inside to outside, this deflection reflects the depolarization vector from the endocardium to the epicardium.

  9. Coronary arteries - Wikipedia

    en.wikipedia.org/wiki/Coronary_arteries

    These categories are called epicardial (above the epicardium, or the outermost tissue of the heart) and microvascular (close to the endocardium, or the innermost tissue of the heart). [ 2 ] Reduced function of the coronary arteries can lead to decreased flow of oxygen and nutrients to the heart.
