Chapter 17 Cardiovascular Emergencys Flashcards
A group of symptoms caused by myocardial ischemia includes angina and myocardial infarction
Acute coronary syndrome ACS
A heart attack deaths of the heart muscles, following obstruction of blood flow to it acute in this context means new or happening right now
Acute myocardial infarction AMI
Transient, short-lived chest discomfort caused by partial or temporary blockage of blood flow to the heart muscle also called angina
Angina pectoris
The front surface of the body, the side facing you in standard anatomic position
Anterior
The main artery which receives blood from the left ventricle, and delivers it to all other arteries that carry blood to the tissues of the body
Aorta
a bulge that occurs in the wall of the major blood vessel (aorta) that carries blood from the heart to the body
Aortic aneurysm
The one-way valve that lies between the left ventricle, and the aorta that keeps blood from flowing back into the left ventricle after the left ventricle ejection it’s blood into the aorta one of four heart valves
Aortic valve
A tracing on an ECG that is the result of interference, such as patient movement rather than a heart electrical activity
Artifact
The complete absence of all heart electrical activity
Asystole
A disorder in which cholesterol in calcium build up inside the walls of blood vessels, eventually leading to partial or complete blockage of blood flow
Atherosclerosis
One of the two upper chambers of the heart
Atrium
The ability of cardiac muscle cells to contract without stimulation from the nervous system
Automaticity
Part of the nervous system, that controls involuntary activities of the body, such as heart rate, blood pressure in digestion of food
Autotomic nervous system
A slow heart rate less than 60 beats a minute
Bradycardia
When the heart fails to generate effective and detectable blood flow, pulses, or not palpable in cardiac arrest, even if muscular and electrical activity continues in the heart
Cardiac arrest
A measure of the volume of blood, circulator by the heart, in one minute, calculated by multiplying the stroke, volume by the heart rate
Cardiac output
A state in which not enough oxygen is delivered to the tissues of the body caused by lowly output of blood from the heart. It can be severe complication of a large, acute myocardial infarction, as well as other conditions.
Cardiogenic shock
A disorder in which the heart loses part of its ability to effectively pump blood, usually as a result of damage to the heart muscle, and usually resulting in back up of fluid into the lungs
Cognitive heart failure CHF
The blood vessels that carry blood and nutrients to the heart
Coronary arteries
To shock a fibrillating, chaotically, shaking heart with specialize electric current in an attempt to restore a normal rhythmic beat
Defibrillate
Swelling in the part of the body, closest to the ground, caused by collection of fluid in the tissues, a possible sign of cognitive heart failure
Dependent edema
Winding of a tubular structures, such as a coronary artery
Dilation
A condition in which the inner layers of an artery, such as the aorta become separated, allowing blood at high pressures to flow between layers
Dissecting aneurysm
An irregular or abnormal heart rhythm
Dysrhythmia
