Anatomy
Body structures, vessels, chambers, and structural terminology.
Glossary route
Cardiology Terms Explained
This route explains how core cardiology pages connect from anatomy to disease to testing and action.
Why this route exists
Cardiology is one of the best glossary clusters for programmatic SEO because the topics naturally form strong topic webs.
A learner can move from structures to physiology, then to ischemia, then to tests like ECG and echocardiography, and finally to intervention terms.
How to use this page
- Start with chambers, valves, and vessels.
- Add heartbeat and circulation physiology.
- Move into ischemia, infarction, and diagnostic tests.
Recommended Categories
Physiology
Normal function, regulation, and core body-system language.
Cardiology
Heart disease, ischemia, vascular findings, and cardiac procedures.
Diagnosis
Tests, measurements, and terms used to evaluate patients.
Pathology
Disease mechanisms, lesions, and abnormal clinical findings.
Best Terms to Start With
Aorta
The main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen, where it splits into two smaller arter...
Left Atrium
The upper chamber of the heart that receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle.
Left Ventricle
The lower left chamber of the heart that receives oxygenated blood from the left atrium and pumps it into the systemic circulation via the aorta.
Mitral Valve
The bicuspid valve located between the left atrium and left ventricle that prevents backflow of blood during ventricular systole.
Systole
The phase of the cardiac cycle during which the heart muscle contracts, ejecting blood from the ventricles into the aorta and pulmonary artery.
Diastole
The phase of the cardiac cycle during which the heart muscle relaxes and the chambers fill with blood, comprising approximately two-thirds of the cardiac cycle duration.
Electrocardiogram
A graphical recording of the electrical activity of the heart over time, obtained via electrodes placed on the skin, used to diagnose cardiac arrhythmias, ischemia, and...
Echocardiography
A non-invasive ultrasound imaging technique used to visualize cardiac structures, assess ventricular function, valvular abnormalities, and hemodynamics.
Myocardial Infarction
Necrosis of myocardial tissue due to prolonged ischemia, typically caused by acute thrombotic occlusion of a coronary artery.
Stable Angina
Predictable chest pain or discomfort provoked by physical exertion or emotional stress, relieved by rest or nitroglycerin, caused by fixed coronary artery stenosis.
Coronary Stenosis
Narrowing of the coronary arteries due to atherosclerosis, reducing blood flow to the heart muscle.
Atherosclerotic Plaque
A pathological accumulation of lipids, fibrous tissue, and inflammatory cells in the arterial intima, leading to vessel narrowing and potential ischemia.
