    Study Notes

    Cardiovascular Terminology

    • Cardiologist: Specialist in diagnosing and treating heart conditions.
    • Cardiology: Medical field focused on heart diseases.
    • Cardiopulmonary Resuscitation (CPR): Emergency procedure to restore heart and lung function.

    Heart Structure and Function

    • Cardiovascular: Relates to the heart and blood vessels.
    • Mediastinum: Area between the lungs containing crucial structures like the heart and major blood vessels.
    • Sternum: The long, flat bone forming the center of the chest wall.

    Blood Circulation and Vessels

    • Aorta: Main trunk of the systemic arterial system, distributing oxygen-rich blood.
    • Coronary Circulation: Blood vessels supplying the heart muscle; critical for heart health.

    Cardiac Muscle and Layers

    • Myocardium: The muscular layer of the heart responsible for contraction.
    • Endocardium: Inner lining of the heart chambers, crucial for proper function.
    • Epicardium: Outer layer of the heart wall, also considered part of the pericardium.

    Diagnostic Tools

    • Electrocardiogram (ECG/EKG): A record of electrical signals in the heart, used to detect abnormalities.
    • Electrode: Device used for conducting electricity in medical tests related to heart activity.

    Procedures and Specialties

    • Phlebotomist: Professional trained to draw blood from veins for testing.
    • Phlebotomy: The process of drawing blood, essential for diagnostic procedures.

    Cardiovascular Conditions

    • Ischemia: Insufficient blood supply to tissue, can lead to serious complications.
    • Necrosis: Pathological death of cells or tissues due to severe ischemia.

    Heart Valves and Chambers

    • Atria/Atrium: Chambers where blood enters the heart, located on both sides.
    • Ventricles: Lower chambers of the heart, responsible for pumping blood out.
    • Bicuspid Valve: Valve with two flaps (also known as the mitral valve).
    • Tricuspid Valve: Valve with three flaps between the right atrium and ventricle.

    Electrical Activity and Heart Rhythm

    • Arrhythmia: Abnormal heart rhythm, which can affect heart function.
    • Sinoatrial (SA) Node: The heart's natural pacemaker located in the right atrium, regulating rhythm.
    • Sinus Rhythm: The normal heart rhythm originating from the SA node.
    • Dysrhythmia: A broader term for any abnormal heart rhythm.

    Blood Pressure and Heart Function

    • Diastole: Phase of the heartbeat when the heart muscles relax and chambers fill with blood.
    • Diastolic: Relating to the diastole phase of the cardiac cycle.

    Membranes and Protective Structures

    • Pericardium: Double-layered membrane surrounding the heart, providing protection and lubrication.
    • Pericardial: Pertaining to the pericardium.

    Clinical Observations

    • Diaphoresis: Excessive sweating, indicating distress or a medical condition.
    • Murmur: An abnormal heart sound, potentially indicating valve issues.
