Study Notes
Anatomy and Function of the Heart
- The heart has four chambers: left atrium, right atrium, left ventricle, right ventricle.
- Oxygen-rich blood is managed by the left side, while the right side handles oxygen-poor blood.
- The septum, a thick muscle wall, separates the left and right sides of the heart.
Heart Valves and Blood Flow
- The mitral valve connects the left atrium and ventricle; the aortic valve connects the left ventricle to the aorta.
- The tricuspid valve connects the right atrium and ventricle; the pulmonary valve connects the right ventricle to the pulmonary artery.
- Heart valves prevent blood from flowing backward, ensuring unidirectional flow.
Blood Circulation
- The left ventricle pumps blood into the aorta, which branches into smaller arteries, leading to capillaries for nutrient and waste exchange.
- Blood returns to the heart through veins, collecting into the superior and inferior vena cava into the right atrium.
Heart Structures and Terminology
- Atria are the upper chambers; ventricles are the lower chambers, also referred to as muscle (ventricul/o).
- Valves: atrioventricular valves and those between ventricles and arteries.
- Septum, derived from Latin, refers to any wall dividing cavities, evident in various body structures.
Diagnostic Procedures
- An echocardiogram utilizes ultrasound to visualize heart structures.
- An electrocardiogram measures electrical signals in the heart using electrodes.
- Angiograms involve injecting dye for x-ray visualization of blood vessels to detect blockages or abnormalities.
Cardiac Conditions and Symptoms
- Common symptoms of heart issues include chest pain (pectoralgia), irregular heartbeats (arrhythmia, dysrhythmia), and palpitation (rapid heartbeat).
- Angina pectoris describes oppressive chest pain from irregular blood flow.
- Systolic pressure (systole) measures arterial pressure during heartbeats; diastolic pressure (diastole) measures pressure when the heart is at rest.
Conditions Related to Blood Vessels
- Atherosclerosis indicates hardening of arteries due to fatty plaque buildup, contributing to cardiovascular diseases.
- Hemorrhage refers to significant blood loss; ischemia indicates blockage of blood flow to organs.
- Varicose veins are enlarged veins near the skin's surface; phlebalgia denotes vein pain.
Important Vascular Terms
- Angiogenesis is the development of blood vessels, while angiosclerosis refers to their hardening.
- Thrombus is a stationary blood clot; embolus is a traveling mass causing blockages.
- Vasospasm refers to involuntary contraction of blood vessels, impacting blood flow.
Key Cardiac Anatomy
- The pericardium surrounds the heart; myocardium is heart muscle tissue; endocardium lines the heart's inner surface.
- Main blood vessels: aorta carries oxygenated blood from the heart; vena cava returns deoxygenated blood from the body.
Surgical and Diagnostic Interventions
- Cardiac catheterization involves inserting a catheter into the heart for diagnosis or treatment.
- Angioplasty is a procedure to open blocked arteries using balloons or stents.
- Diagnostic angiography records blood vessel conditions and detects issues like atherogenesis or occlusion.### Cardiology Terms and Definitions
- Echocardiogram: An image of the heart created using sound waves, similar to an ultrasound, specifically targeting cardiac structures.
- Echocardiography: The process of capturing heart images through sound waves, effectively visualizing heart function and anatomy.
Electrical Cardiology
- Electrocardiogram (ECG): A record of the heart's electrical activity, crucial for diagnosing arrhythmias and other heart conditions.
- Electrocardiography: The procedure to record the heart’s electrical currents, providing critical insights into cardiac health.
Diagnostic Imaging
- Sonography: A technique using sound waves to produce images for medical diagnostics, commonly referred to as ultrasound.
Exercise Testing
- Stress Electrocardiogram: Monitors the electrical signals of the heart under stress, typically during physical exercise, to evaluate cardiac function.
Advanced Imaging Techniques
- Transesophageal Echocardiogram: A specialized echocardiogram performed by inserting a transducer into the esophagus to achieve detailed images of the heart.
Vascular Procedures
- Vascular Endoscopy: A procedure to visually inspect the interior of blood vessels, aiding in diagnosis and treatment.
- Venogram: An imaging technique to visualize veins, essential for diagnosing venous diseases.
Blood Pressure Monitoring
- Blood Pressure: Indicates the force of circulating blood against blood vessel walls, a key health metric.
- Diastolic Pressure: Measures the pressure in blood vessels when the heart is at rest between beats.
- Systolic Pressure: Reflects the pressure exerted on arteries when the heart contracts, essential for blood pressure assessment.
Cardiology Specialties
- Cardiologist: A physician specializing in diagnosing and treating heart conditions.
- Cardiology: The medical specialty focusing on the heart's structure and function.
Cardiovascular System
- Cardiovascular: Pertaining to the heart and blood vessels, crucial for understanding systemic health.
- Circulation: The process of blood flow from the heart through vessels and back, essential for maintaining bodily functions.
Circulatory Routes
- Coronary Circulation: Blood flow from the heart to the heart muscle, ensuring it receives oxygen-rich blood first.
- Pulmonary Circulation: The route blood takes from the heart to the lungs for oxygenation.
- Systemic Circulation: Blood circulation from the heart to the rest of the body, delivering oxygen and nutrients.
Vein Specialists
- Phlebologist: A specialist focused on the study and treatment of vein-related conditions.
- Phlebology: The branch of medicine that deals with veins and associated disorders.
- Phlebotomist: A healthcare professional trained to draw blood from patients for testing purposes.
- Phlebotomy: The procedure of making an incision into a vein to obtain blood.
Inflammatory Conditions
- Angiocarditis: Inflammation of the vessels supplying the heart, which can affect cardiac function.
- Atrial Fibrillation: A condition characterized by rapid and irregular heartbeats originating from the heart's atrium.
Congenital Heart Defects
- Atrial Septal Defect (ASD): A congenital defect in the heart's septum that separates the atria, allowing blood to flow abnormally between them.
