    Study Notes

    Assessment Techniques

    • Inspection: Observing using sight, smell, and sound to identify normal or abnormal findings.
    • Palpation: Utilizing touch to assess for expected or abnormal conditions.
    • Auscultation: Listening with a stethoscope to detect sounds not perceivable by the human ear.

    Stethoscope Functions

    • Diaphragm: Detects high-pitched sounds when pressed firmly against the skin, ideal for breath sounds.
    • Bell: Picks up low-pitched sounds, such as extra heart sounds, when held lightly against the skin.

    Anatomical Landmarks

    • Precordium: The area of the chest that covers the heart and major vessels.
    • Intercostal Space (ICS): The region between adjacent ribs.
    • Midclavicular Line (MCL): An imaginary line that runs parallel to the body’s long axis through the clavicle midpoint.

    Cardiac Structure

    • Apex of the Heart: The heart's bottom tip located at the left 5th ICS MCL.
    • Base of the Heart: The top part of the heart.

    Heart Valves

    • Atrioventricular (AV) Valves: Comprises the tricuspid and mitral (bicuspid) valves.
    • Semilunar Valves: Includes the pulmonic and aortic valves.

    Heart Surroundings

    • Pericardium: A fibrous sac enveloping the heart, providing protection.

    Cardiac Electrophysiology

    • Electrocardiogram (EKG/ECG): Records the electrical activity of the heart muscle.
    • Cardiac Cycle: Encompasses diastole (relaxation and filling) and systole (contraction and emptying).

    Abnormal Sounds and Conditions

    • Bruit: A blowing sound indicating turbulent arterial blood flow due to narrowing.
    • Murmur: An abnormal sound signaling turbulent blood flow through heart valves or vessels.

    Physical Findings

    • Heaves (Lifts): Abnormal pulsations seen on the right precordium.
    • Thrills: Vibrations felt upon palpation, associated with significant murmurs.

    Cardiac Conditions

    • Myocardial Infarction (MI): Heart tissue damage due to insufficient blood supply.
    • Congestive Heart Failure (CHF): Heart's inability to pump efficiently, leading to fluid buildup.

    Acute Conditions

    • Acute Coronary Syndrome: A spectrum of symptoms arising from plaque rupture and thrombosis in coronary arteries.

    Hemodynamics

    • Afterload: Resistance encountered during ejection of blood from the ventricle.
    • Preload: Stretch of cardiac muscle fibers at diastole's end.

    Cardiac Monitoring

    • Hemodynamic Monitoring: Measurement of cardiovascular function using pressure devices.
    • Cardiac Catheterization: An invasive method to assess heart pressure and blood vessel status.

    Cardiac Functions

    • Cardiac Output (CO): Volume of blood pumped by each ventricle per minute.
    • Stroke Volume: Amount of blood ejected per heartbeat.

    Electrical Activity

    • Depolarization: Electrical activation involves sodium influx and potassium outflow.
    • Repolarization: Returns the cardiac cell to its resting state, facilitated by potassium influx and sodium exit.

    Blood Pressure Conditions

    • Hypertension: Consistent blood pressure above 140/90 mmHg.
    • Hypotension: Blood pressure falling below 100/60 mmHg, impairing blood flow.

    Heart Sounds

    • Normal Heart Sounds: S1 (closure of AV valves) and S2 (closure of semilunar valves).
    • Abnormal Sounds: S3 (indicates heart failure) and S4 (suggests ventricular hypertrophy).

    Pacemakers of the Heart

    • Sinoatrial (SA) Node: The primary pacemaker generating electrical impulses in the right atrium.
    • Atrioventricular (AV) Node: The secondary pacemaker located near the tricuspid valve.

    Other Terms

    • Telemetry: Continuous ECG monitoring via radio waves transmitted from a patient-worn device.
    • Systemic Vascular Resistance: Resistance faced by blood leaving the left ventricle, influenced by systemic circulation.
