Outline of cardiology

Outline of cardiology is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Outline of cardiology rather than just read about it. In short: The following outline is provided as an overview of and topical guide to cardiology, the branch of medicine dealing with disorders of the human heart. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

Key takeaways

Outline of cardiology belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Outline of cardiology to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Outline of cardiology from memory before moving on to harder problems.

Reference excerpt

The following outline is provided as an overview of and topical guide to cardiology, the branch of medicine dealing with disorders of the human heart. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in cardiology are called cardiologists.

What type of thing is cardiology? Cardiology can be described as all of the following:

An academic discipline Branch of science Branch of applied science Branch of medicine Branch of internal medicine

Branches of cardiology Adult cardiology – Cardiac electrophysiology – study of the electrical properties and conduction diseases of the heart. Clinical cardiac electrophysiology –Clinical cardiac electrophysiology, is a branch of the medical specialty of cardiology and is concerned with the study and treatment of rhythm disorders of the heart. Cardiologists with expertise in this area are usually referred to as electrophysiologists. Electrophysiologists are trained in the mechanism, function, and performance of the electrical activities of the heart. Cardiogeriatrics (geriatric cardiology) –Cardiogeriatrics, or geriatric cardiology, is the branch of cardiology and geriatric medicine that deals with the cardiovascular disorders in elderly people. Echocardiography – use of ultrasound to study the mechanical function/physics of the heart. Interventional cardiology – use of catheters for the treatment of structural and ischemic diseases of the heart. Nuclear cardiology – use of nuclear medicine to visualize the uptake of an isotope by the heart using radioactive sources. Pediatric cardiology – Pediatric cardiologists specialize in diagnosing and treating heart problems in children.

Anatomy of the heart Heart –

Chordae tendinae – Right atrium – Right ventricle – Tricuspid valve – Left atrium – Left ventricle – Mitral valve – Endocardium – Myocardium – Pericardial cavity – Transverse pericardial sinus – Pericardium –

Physical exam

The cardiac physical exam focuses on portions of the physical exam that elucidate information about diseases and disorders outlined below. Clinical judgment, of course, should guide the physical exam but the following are pertinent things related to a general / broad cardiac exam.

Apex beat (point of maximum impulse) Bruits: carotid, renal Edema of the lower extremities and ascites that may indicate right heart failure Heart sounds, heart murmurs, pericardial rub, mechanical heart valve clicking Jugular venous distension Retina exam with ophthalmoscope for signs of hypertension (retinal hemorrhage) and diabetic retinopathy (cotton wool spots) Pulses: carotid, dorsalis pedis, femoral, popliteal, posterior tibial, radial, temporal, ulnar Heart rate Pulse quality: pulsus paradoxus, pulsus parvus et tardus Respiratory sounds for crackles (edema) and other lung pathologies that can affect the heart Rheumatic diseases can have significant cardiac findings and is too lengthy to include here Arthritis is common amongst rheumatic diseases Skin exam for rashes (systemic lupus erythematosus, scleroderma, dermatomyositis, vasculitis) Skin exam Diabetic neuropathy Endocarditis signs: Janeway lesions, Osler's nodes, splinter hemorrhages Peripheral vascular disease Scars indicating procedures: sternotomy, thoracotomy, pericardial window, carotid endarterectomy, thyroidectomy, etc. Skin bulges indicating implanted devices: pacemaker, ICD, implantable loop recorder, vagus nerve stimulation Vasculitis rashes Xanthomas & xanthelasmas Vital signs Blood pressure – hypertension, congenital heart disease manifestations Heart rate – bradycardia & tachycardia Respiratory rate – in distress, shortness of breath causes

Worked examples

Example 1 — a first encounter with Outline of cardiology

Start with the simplest possible case. Write down what Outline of cardiology claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Outline of cardiology before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Outline of cardiology ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Outline of cardiology

In research: Outline of cardiology appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Outline of cardiology in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Outline of cardiology is common in secondary-school and first-year university syllabi. It links to neighbouring topics Cardiology, Outlines, Outlines of health and fitness, so understanding it makes those chapters shorter.
In everyday life: Look for Outline of cardiology outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
