includes angina and myocardial infarction acute coronary syndrome A group of symptoms caused by myocardial ischemia; includes angina and myocardial infarction acute coronary syndrome A heart attack; death of the heart muscle following obstruction of blood flow to it; in this context the attack is "new" or "happening right now" acute myocardial infarction (AMI) A heart attack; death of the heart muscle following obstruction of blood flow to it; in this context the attack is "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 Transient (short-lived) chest discomfort caused by partial or temporary blockage of blood flow to the heart muscle; also called angina angina pectoris a weakness in the wall of the aorta that makes it susceptible to rupture aortic aneurism a weakness in the wall of the aorta that makes it susceptible to rupture aortic aneurism the one way valve that lies between the left ventricle and the aorta keeps blood from flowing back into the left ventricle after the left ventricle ejects its blood into the aorta; one of the four heart valves aortic valve the one way valve that lies between the left ventricle and the aorta keeps blood from flowing back into the left ventricle after the left ventricle ejects its blood into the aorta; one of the four heart valves aortic valve a tracing on an ECG that is the result of interference, such as patient movement, rather than the heart's electrical activity artifact a tracing on an ECG that is the result of interference, such as patient movement, rather than the heart's electrical activity artifact the complete absence of all heart electrical activity asystole the complete absence of all heart electrical activity asystole the ability of cardiac muscle cells to contract without stimulation from the nervous system automatically the ability of cardiac muscle cells to contract without stimulation from the nervous system automatically when the heart fails to generate effective and detectable blood flow; pulses are not palpable, even if muscular and electrical activity continues in the heart cardiac arrest when the heart fails to generate effective and detectable blood flow; pulses are not palpable, even if muscular and electrical activity continues in the heart cardiac arrest a disorder in which the hear loses part of its ability to effectively pump blood, usually as a result of damage to the heart muscle and usually resulting in a backup of fluid into the lungs congestive heart failure a disorder in which the hear loses part of its ability to effectively pump blood, usually as a result of damage to the heart muscle and usually resulting in a backup of fluid into the lungs congestive heart failure the blood vessels that carry blood and nutrients to the heart muscle coronary arteries the blood vessels that carry blood and nutrients to the heart muscle coronary arteries to shock the fibrillating (chaotically beating) heart with specialized electric current in an attempt to restore a normal, rhythmic beat defibrillate to shock the fibrillating (chaotically beating) heart with specialized 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 the collection of fluid in the tissues; a possible sign of congestive heart failure dependent edema swelling in the part of the body closest to the ground, caused by the collection of fluid in the tissues; a possible sign of congestive heart failure dependent edema Widening of a tubular structure such as a coronary artery. dilation Widening of a tubular structure such as a coronary artery. dilation a condition in which the inner layers of an artery, such as the aorta, become seperatated, allowing blood (at high pressures) to flow between the layers dissecting aneurysm a condition in which the inner layers of an artery, such as the aorta, become seperatated, allowing blood (at high pressures) to flow between the layers dissecting aneurysm An irregular or abnormal rhythm of the heart dysrhythmia An irregular or abnormal rhythm of the heart dysrhythmia an emergency situation created by excessively high blood pressure, which can lead to serious complications such as a stroke or aneurysm hypertensive emergency an emergency situation created by excessively high blood pressure, which can lead to serious complications such as a stroke or aneurysm hypertensive emergency death of body tissues, usually caused by interruption of its blood supply infarction death of body tissues, usually caused by interruption of its blood supply infarction the inside diameter of an artery or other hollow structure lumen the inside diameter of an artery or other hollow structure lumen the heart muscle myocardium the heart muscle myocardium a blockage, usually of a tubular structure such as a blood vessel occlusion a blockage, usually of a tubular structure such as a blood vessel occlusion a blood clot that has formed within a blood vessel and is floating within the bloodstream thromboembolism a blood clot that has formed within a blood vessel and is floating within the bloodstream thromboembolism disorganized, ineffective quivering of the ventricles, resulting in no blood flow and a state of cardiac arrest ventricular fibrillation disorganized, ineffective quivering of the ventricles, resulting in no blood flow and a state of cardiac arrest ventricular fibrillation a rapid heart rhythm in which the electrical impulse begins in the ventricle (instead of the atrium), which may result in inadequate blood flow and eventually deteriorate into cardiac arrest ventricular tachycardia a rapid heart rhythm in which the electrical impulse begins in the ventricle (instead of the atrium), which may result in inadequate blood flow and eventually deteriorate into cardiac arrest ventricular tachycardia How does nitro work? vasodilation and increased cardiac oxygen demand How does nitro work? vasodilation and increased cardiac oxygen demand pulmonary edema fluid in the air sacs and bronchioles of the lung; cannot breathe while lying down pulmonary edema fluid in the air sacs and bronchioles of the lung; cannot breathe while lying down Patient presents with weakness and nausea. She is conscious and alert and her skin is cool and clammy. BP is 140/88, pulse is 70 and regular, and R is 16 and unlabored. She has hypertension (high BP), diabetes, and a pacemaker. What should you suspect? AMI (heart attack) Patient presents with weakness and nausea. She is conscious and alert and her skin is cool and clammy. BP is 140/88, pulse is 70 and regular, and R is 16 and unlabored. She has hypertension (high BP), diabetes, and a pacemaker. What should you suspect? AMI (heart attack) left ventricular assist device Booster pump implanted in the abdomen with a tube inserted into the left ventricle. An LVAD is a "bridge to transplant" or destination therapy when heart transplantation is impossible.
