Implantable Cardioverter/Defibrillator (ICD) - correct answer Device that delivers
electrical shock that completely depolarizes the myocardium, producing brief asystole.
This allows SA node to regain control of the electrical activity.
Infarct - correct answer An area of tissue that undergoes necrosis following cessation
of blood supply. Results from stenosis or occlusion of supplying artery.
Intermittent claudication - correct answer Cramping in leg muscles brought on by
predicable amount of walking and relieved by rest. This is a marker for peripheral

-increases FORCE of contraction
Premature ventricular contraction - correct answer When the ventricles beat before the
regular time. The ventricles receive an electrical signal from other place besides SA
node. If this happens more than 3 times in a row=ventricular tachycardia.

myocardial injury. Peak is 1-2 hours and declines after 7 hours, gone w/i 24 hours. Male
