  2. Anomalous diffusion - Wikipedia

    en.wikipedia.org/wiki/Anomalous_diffusion

    The classes of anomalous diffusions are classified as follows: α < 1: subdiffusion. This can happen due to crowding or walls. For example, a random walker in a crowded room, or in a maze, is able to move as usual for small random steps, but cannot take large random steps, creating subdiffusion.

  3. Scimitar syndrome - Wikipedia

    en.wikipedia.org/wiki/Scimitar_syndrome

    Chest x-ray of a five-year-old girl with Scimitar syndrome. The heart (blue outline) is shifted into the right half of the chest, and the anomalous pulmonary venous return (red) has a shape reminiscent of a Scimitar. The diagnosis is made by transthoracic or transesophageal echocardiography [citation needed] and selective pulmonary angiography. [5]

  4. Isolated levocardia - Wikipedia

    en.wikipedia.org/wiki/Isolated_levocardia

    A Blalock-Taussig operation performed by Dr. Alfred Blalock in 1947 helped to significantly improve the condition of the patient. Before the operation, the patient was diagnosed to have isolated levocardia, pulmonary stenosis, overriding aorta with a right aortic arch and anomalous return of the pulmonary and systemic circulations.

  5. Anomalous left coronary artery from the pulmonary artery

    en.wikipedia.org/wiki/Anomalous_Left_Coronary...

    The diagnosis comprises between 0.24 and 0.46% of all cases of congenital heart disease. [1] The anomalous left coronary artery (LCA) usually arises from the pulmonary artery instead of the aortic sinus. In fetal life, the high pressure in the pulmonic artery and the fetal shunts enable oxygen-rich blood to flow in the LCA.

  6. Coronary artery anomaly - Wikipedia

    en.wikipedia.org/wiki/Coronary_artery_anomaly

    Coronary arteries are vessels supplying blood and nutrients to the heart muscle (). [1]Coronary arteries arise from ostia, openings of the aorta (the largest artery in the human body) at the upper third or middle third of the sinuses of Valsalva (the first part of the big pipe coming off the main pumping chamber).

  7. Ectopic pacemaker - Wikipedia

    en.wikipedia.org/wiki/Ectopic_pacemaker

    In a normal heart beat rhythm, the SA node usually suppresses the ectopic pacemaker activity due to the higher impulse rate of the SA node. However, in the instance of either a malfunctioning SA node or an ectopic focus bearing an intrinsic rate superior to SA node rate, ectopic pacemaker activity may take over the natural heart rhythm. [3]

  8. Syndromes affecting the heart - Wikipedia

    en.wikipedia.org/wiki/Syndromes_affecting_the_heart

    Congenital heart problems e.g. pulmonary artery stenosis (common), Tetralogy of Fallot, overriding aorta, ventricular septal defect; and right ventricular hypertrophy. Liver (jaundice, pruritus, hepatosplenomegaly, acholia, xanthoma) Andersen–Tawil syndrome: This condition affects the QT interval (in blue) Antley–Bixler syndrome: Barth syndrome

  9. Inward-rectifier potassium channel - Wikipedia

    en.wikipedia.org/wiki/Inward-rectifier_potassium...

    Atherosclerosis (heart disease) may be related to K ir channels. The loss of K ir currents in endothelial cells is one of the first known indicators of atherogenesis (the beginning of heart disease). Thyrotoxic hypokalaemic periodic paralysis has been linked to altered K ir 2.6 function. [19] EAST/SeSAME syndrome is caused by mutations in ...
