Knowra Cardiology Cardiology Cardiology is the medical specialty concerned with the heart, blood vessels, and disorders of the cardiovascular system. It includes diagnosis, treatment, and prevention of these conditions.
Electrocardiography : A method of recording the heart’s electrical activity using electrodes on the skin. It detects rhythm disorders and electrical signs of heart disease.
Heart : A muscular organ that pumps blood through the lungs and the rest of the body. Its chambers, valves, and electrical system are central subjects of cardiology.
Atherosclerosis : A disease in which lipid-rich plaques accumulate in artery walls and can restrict blood flow. It is a major cause of coronary artery disease and cardiovascular events.
Cardiothoracic surgery : The surgical specialty treating diseases of the heart, lungs, and other organs in the chest. It provides operative treatments that differ from cardiology’s mainly diagnostic and nonsurgical care.
Echocardiography : Ultrasound imaging that shows the heart’s structure, movement, and blood flow. It lets cardiologists assess valves, chambers, and pumping function.
Cardiovascular system : The network of the heart and blood vessels that circulates blood through the body. Cardiology addresses disorders across this entire circulatory network.
Myocardial infarction : Irreversible injury to heart muscle caused by prolonged loss of blood flow. It is a time-critical consequence of coronary blockage.
Vascular surgery : A surgical specialty focused on diseases of arteries, veins, and lymphatic vessels outside the heart and brain. Its scope overlaps cardiology in vascular disease but centers on surgical management.
Coronary angiography : An imaging procedure that uses contrast dye and X-rays to show blood flow through coronary arteries. It identifies narrowed or blocked arteries supplying the heart.
Coronary circulation : The blood supply that serves the heart muscle through the coronary arteries and veins. Disrupted coronary blood flow causes many urgent conditions treated in cardiology.
