Question

BIOL242 Vemier Lab 12- Pre lab Name 1. In this lab, you will generate a graphic recording of the electrical changs that ocor in the hean during the cardiac cycle. This is known as hean a. MRI b. CT scan c. Electrocardiogram f. AED- automated external defibrillator 2. Which statement below accurately describes the electrical activity occurring in the heart immediately prior to the occurrence of the P wave a. There is no measurable electrical activity occurring (not measurable on EKG) b. The atrial musele cells are depolarizing c. The atrial mascle cells are repolarizing d. The ventricular muscle cells are depolarizing e. The ventricular muscle cells are repolarizing 3. An ECG (or EKG) a. Shows you only the action potentials of the SA node and AV mode cells b. Shows you one action potential of an average cardiac muscle cell c. Is a trace of muscle tension generated during the cardiac cycle d. Can give you information about the heart rate e. A and D . B and D True or False The P wave is typically taller than the QRS complex. The repolarization of the atria occurs during the QRS complex. 6. The first heart sound,"lub", is represented by the P wave.
Please answer

Answer 1

1. Graphic recording of the electrical charges that occur during the cardiac cycle is called electrocardiogram(option c) 2.The electrical activity of occuring in the heart immediately prior to the occurrence of the p wave is there is no measurable electrical activity(option a). 3.The EKG (option e both a and d) 4.false. 5.false. 6.false
