Study Notes

Medical Terminology Overview

  • Cyanosis: Bluish discoloration of the skin, often indicative of low oxygen levels.
  • Raynaud Disease: Characterized by recurrent episodes of pallor and cyanosis, primarily affecting fingers and toes.
  • Heart Block: Condition where normal conduction of electrical impulses in the heart is disrupted.
  • Ischemia: Refers to a lack of blood supply to tissues, without adequate oxygenation.
  • Atheroma: A buildup of plaque inside the arterial walls, which can lead to cardiovascular diseases.
  • Vasoconstriction: The narrowing of blood vessels, which can increase blood pressure.
  • Myocardial Infarction: An event where heart tissue dies due to lack of blood supply, commonly referred to as a heart attack.
  • Angina: Severe chest pain due to inadequate blood flow to the heart muscle (myocardium).
  • Thrombotic Occlusion: The blockage of an artery caused by a thrombus, or blood clot.
  • HDL: High-density lipoprotein, known as "good cholesterol," which helps remove other forms of cholesterol from the bloodstream.

Heart Structure and Function

  • SA Node: Sinoatrial node, known as the heart's natural pacemaker, initiating electrical impulses.
  • Pericardium: The saclike membrane surrounding and protecting the heart, composed of double layers.
  • Systole: The phase of the heartbeat during which the heart muscle contracts and pumps blood.
  • Diastole: The phase of the heartbeat where the heart muscle relaxes and chambers fill with blood.
  • Murmur: An abnormal sound indicating improper closure of heart valves.
  • Arteriosclerosis: The hardening of arteries, potentially leading to high blood pressure and heart disease.
  • Cardiomegaly: Enlargement of the heart, often a response to overwork or disease.
  • Thrombophlebitis: Inflammation of a vein with an associated clot, which can lead to pain and swelling.

Cardiac Conditions and Symptoms

  • Tachycardia: A condition characterized by an abnormally rapid heart rate.
  • Arrhythmia: An abnormal heartbeat rhythm, which can vary from too fast to too slow.
  • Hypercholesterolemia: High levels of cholesterol in the blood, increasing the risk for heart disease.
  • Hypoxia: A decreased oxygen condition affecting various tissues throughout the body.
  • Phlebitis: Inflammation of a vein, which can lead to clot formation and further complications.
  • Fibrillation: A type of arrhythmia causing rapid, ineffective heart contractions.

Procedures and Measurements

  • Endarterectomy: A surgical procedure to remove plaque from the inner lining of an artery.
  • Phlebotomy: The incision or puncture of a vein to draw blood for testing or treatment.
  • Sphygmomanometer: An instrument used to measure blood pressure.
  • Deep Vein Thrombosis: The formation of a blood clot in a large vein, typically in the lower limb.
  • Electrocardiogram (ECG): A recording of the electrical activity of the heart, useful for diagnosing heart conditions.
  • Thrombolysis: The process of dissolving blood clots, often used to treat thrombosis.

Specialized Terms

  • Myocardium: The muscular tissue of the heart responsible for contraction.
  • Aneurysm: A local widening of an artery which can rupture, leading to severe complications.
  • Endothelium: The innermost lining of blood vessels, crucial for vascular health and function.
  • Embolus: A traveling clot that can block a blood vessel, leading to serious conditions like stroke or heart attack.
  • Coronary Arteries: Blood vessels branching from the aorta providing oxygen-rich blood to the heart muscle.
  • Tetralogy of Fallot: A congenital heart defect involving four distinct heart anomalies.

Understanding these terms and conditions helps in the diagnosis and treatment of cardiovascular diseases, critical for medical professionals and students alike.
