Study Notes
Cardiovascular Terms and Conditions
- Acute Coronary Syndrome: A collection of symptoms due to myocardial ischemia, including angina and myocardial infarction.
- Acute Myocardial Infarction (AMI): Also known as a heart attack; characterized by the death of heart muscle from obstructed blood flow.
- Angina Pectoris: Temporary chest pain resulting from partial blockage of blood flow to the heart.
- Atherosclerosis: A condition where cholesterol and calcium buildup leads to plaque formation, causing partial or complete blood flow blockage.
Heart Anatomy and Function
- Aorta: The primary artery that channels blood from the left ventricle to the entire body.
- Aortic Aneurysm: A condition marked by weakness in the aorta's wall, increasing the risk of rupture.
- Aortic Valve: A one-way valve between the left ventricle and aorta, preventing backflow of blood into the ventricle.
- Atrium: Upper chambers of the heart; the right atrium receives blood from the vena cava, while the left receives it from pulmonary veins.
Cardiac Conditions and Symptoms
- Arrhythmia: Irregular heartbeats deviating from the normal rhythm.
- Asystole: Complete lack of electrical cardiac activity, appearing as a flat line on an ECG.
- Bradycardia: Defined as a slow heart rate, specifically fewer than 60 beats per minute.
- Cardiac Arrest: Failure of the heart to produce effective blood flow; pulses are absent despite potential electrical activity.
Cardiac Output and Health
- Cardiac Output: The volume of blood the heart circulates in one minute, calculated by multiplying stroke volume by heart rate.
- Cardiogenic Shock: A condition wherein the heart fails to supply sufficient oxygen to tissues due to low blood flow; often a result of a large heart attack.
- Congestive Heart Failure (CHF): A disorder where the heart's pumping ability is compromised, leading to fluid backup in the lungs.
Emergency Situations
- Defibrillation: The process of delivering an electric shock to restore a normal heartbeat in a fibrillating heart.
- Hypertensive Emergency: A critical state of excessively high blood pressure, risking severe outcomes like stroke or aneurysm.
- Dependent Edema: Swelling in lower parts of the body due to fluid accumulation, commonly associated with CHF.
Additional Terms
- Dilation: The widening of hollow structures, such as coronary arteries.
- Dissecting Aneurysm: A medical emergency where the layers of an artery separate, allowing blood flow between them.
- Infarction: Tissue death caused by interrupted blood supply; often associated with heart or stroke incidents.
- Ischemia: Oxygen deprivation in tissues due to insufficient blood flow, resulting in nutrient deficiency.
