Study Notes

Cardiovascular System Terminology

Aorta: Largest artery that carries blood from the left ventricle to the body.
Aortic Valve: Located at the aorta's entrance, controlling blood flow from the heart.
Apex: The pointed end of a cone-shaped structure, such as the heart.
Artery: Blood vessels that transport oxygenated blood away from the heart.
Arteriole: Small vessels that carry blood from arteries to capillaries.
Atrioventricular Node: Facilitates impulse transmission from the sinoatrial node to the ventricles.
Atrioventricular Valve: Valves located between atria and ventricles, controlling blood flow direction.
Right AV Valve (Tricuspid Valve): Valve between the right atrium and right ventricle.
Left AV Valve (Mitral Valve): Valve located between the left atrium and left ventricle.
Atrium: Upper chambers of the heart responsible for receiving blood.
AV Bundle: A band of fibers transmitting impulses from the AV node through the interventricular septum.
Blood Pressure: The force blood exerts on vessel walls, important for circulation assessment.
Bundle Branches: Pathways of the AV bundle that conduct impulses to both sides of the ventricles.
Capillary: Microscopic vessels where gas, nutrient, and waste exchange occurs between blood and tissues.
Cardiovascular System: Composed of the heart and blood vessels, essential for transportation of blood.
Depolarization: A shift in electrical charge that triggers contraction in muscle cells.
Diastole: The phase of the heartbeat when the heart muscle relaxes.
Electrocardiography: The study of the heart's electrical activity, monitored through surface electrodes.
Endocardium: The membrane lining the heart's chambers and covering its valves.
Epicardium: The outermost layer of the heart’s structure.
Functional Murmur: Sounds produced during the heart's regular operation.
Inferior Vena Cava: Major vein returning deoxygenated blood from the lower body to the heart's right atrium.
Pulmonary Artery: Vessel carrying deoxygenated blood from the heart to the lungs.
Pulmonary Circuit: System that transports blood from the right heart to the lungs and back to the left heart.
Pulmonary Veins: Vessels carrying oxygenated blood from the lungs to the heart.
Pulmonary Valve: Valve controlling blood flow from the right ventricle to the pulmonary artery.
Pulse: The rhythmical wave of pressure that represents heartbeats as blood is pushed through vessels.
Purkinje Fibers: Specialized fibers that distribute electrical impulses throughout the ventricles.
Repolarization: The return of electrical charge to the resting state in muscle cells.
Septum: The dividing wall between the heart's atria and ventricles.
Sinus Rhythm: Normal, regular heart rate indicating healthy heart activity.
Sinoatrial Node: The heart's natural pacemaker, initiating the heartbeat from the right atrium.
Superior Vena Cava: Major vein returning deoxygenated blood from the upper body to the heart's right atrium.
Systemic Circuit: Blood vessels supplying oxygenated blood from the left heart to tissues and returning deoxygenated blood to the right heart.

Health Conditions and Procedures

Aneurysm: Abnormal bulging in a blood vessel, usually due to wall weakness.
Angina Pectoris: Chest pain due to insufficient blood flow to the heart.
Arrhythmia: Irregular heartbeat rates or patterns.
Arteriosclerosis: Loss of artery elasticity due to thickening or hardening from deposits.
Atherosclerosis: Narrowing and hardening of arteries due to fatty deposits.
Bradycardia: Heart rate slower than 60 beats per minute.
Cerebrovascular Accident (Stroke): Sudden brain damage due to reduced blood flow.
Coarctation of the Aorta: Narrowing of the aorta, restricting blood flow.
Deep Vein Thrombosis: Blood clot formation in deep veins.
Dissecting Aneurysm: Aortic aneurysm where blood enters the arterial wall layers.
Dyslipidemia: Abnormal lipid levels in the blood.
Dyspnea: Difficulty breathing, often indicating respiratory or cardiac issues.
Embolism: Blood vessel obstruction caused by a clot or foreign matter.
Fibrillation: Rapid, irregular, and inefficient contractions of heart muscle fibers.
Heart Block: Interference in heart's electrical conduction, causing irregular rhythms.
Heart Failure: Inadequate heart function, failing to maintain blood circulation.
Hemorrhoid: Varicose veins located in the rectal area.
Hypertension: Elevated blood pressure over normal levels.
Infarct: Localized death of tissue due to blood supply blockage.
Ischemia: Insufficient blood supply in a specific area.
Murmur: Unusual heart sounds indicating turbulence in blood flow.
Myocardial Infarction: Heart tissue necrosis due to blood supply obstruction.
Occlusion: Blockage that prevents normal flow in blood vessels.
Patent Ductus Arteriosus: Persistence of the ductus arteriosus post-birth.
Phlebitis: Inflammation of a vein.
Plaque: Fatty deposits on vessel walls that can lead to blockages.
Rheumatic Heart Disease: Heart valve damage following streptococcal infection.
Septal Defect: Opening in the heart's septum leading to blood flow issues.
Shock: Circulatory failure resulting in inadequate blood supply to tissues.
Stenosis: Narrowing of a passage or vessel, affecting blood flow.
Tachycardia: Heart rate exceeding 100 beats per minute.
Thrombophlebitis: Vein inflammation associated with clot formation.
Thrombosis: Blood clot development within a vessel.
Thrombus: A stationary blood clot forming within a vessel.
Varicose Veins: Enlarged veins from valve breakdown, pooling blood.

Medical Procedures and Tests

Ablation: Surgical removal or destruction of tissue.
Angioplasty: Procedure to widen narrowed blood vessels.
Artificial Pacemaker: Device regulating heartbeat by generating impulses.
Cardioversion: Restoration of normal heart rhythm.
Coronary Angiography: X-ray study of coronary arteries post-dye injection.
Coronary Artery Bypass Graft: Surgery creating a shunt to reroute blood around blocked arteries.
Coronary Calcium Scan: Imaging technique to detect calcium deposits in coronary arteries.
Creatine Kinase MB: Enzyme indicating cardiac muscle damage after myocardial infarction.
CT Angiography: Imaging for visualizing blood vessels using injected dye.
Defibrillation: Delivery of electrical shock to restore normal heart rhythm.
