173
Q

implantable cardioverter-defibrillator (ICD)

A

small-battery powered device inserted in chest who is at high risk for developing arrhythmia; aka AICD

174
Q

open heart-surgery

A

surgical procedure in which the sternum is cut in half vertically to open the chest and expose heart, valves, or arteries

175
Q

A

implantation of a battery-powered device inside the chest to control the HR and rhythm

176
Q

defibrillation

A

lifesaving emergency treatment to restart the heart in cardiorespiratory arrest by delivering increase voltage

177
Q

cardioversion

A

defibrillation technique using low-energy shocks to reset hearts rhythm back to its normal pattern

178
Q

angiotensin-converting enzyme (ACE)

A

lower blood pressure by inhibiting the conversion of angiotensin 1 (an inactive enzyme) to angiotensin II (a potent vasoconstrictor)

179
Q

angiotensin II receptor blockers (ARBS)

A

lower blood pressure by blocking the angiotensin II enzyme from causing vasoconstriction

180
Q

antiarrhythmics

A

prevent, alleviate, or correct cardiac arrhythmias (dysrhythmias) by stabilizing the electrical conduction of the heart

181
Q

anticoagulants

A

inhibit the body’s natural coagulation response to prevent the formation of clots in blood vessels

182
Q

beta blockers

A

block the effect of adrenaline, which slows nerve pulses through the heart, causing a decrease in heart rate

183
Q

calcium channel blockers

A

block movement of calcium (required for blood vessel contraction) into myocardial cells and arterial walls, causing heart rate and blood pressure to decrease

184
Q

diurectics

A

act on kidneys to increase excretion of water and sodium

185
Q

nitrates

A

dilate blood vessels of the heart, causing an increase in the amount of oxygen delivered to myocardium and widen blood vessels of the body, allowing more blood flow to the heart

186
Q

statins

A

lower cholesterol in the blood and reduce its production in the liver by blocking the enzyme that produces it
