CHAPTER 8
QUIZ ANSWERS:
1. ICD
2. conductor
3. fibrillation
4. b) 5,400 J
PROBLEMS ANSWERS:
1. As the QRS complex has a large amplitude compared to a P wave or a T wave, this
large amplitude is compared at the voltage comparator for heart rate calculation.
2. 235.3 J
3. First determine the damping situation. Total resistance RTotal = 20 ȍ + 2 * 20 ȍ + 15 ȍ
= 75 ȍ; As RTotal/(2 * L) < 1/(L * C)1/2 ; this is a case of underdamping.
Students should research the answers to Problems 4 and 5 on their own.
6. Total resistance = 81 ȍ;
a) The energy delivered is 50 J
b) The energy delivered is 100 J
