Homework Answers
61. When heart beats it gets depolized. Itr is reported that the depolarized and repolarized both states create electrical activity that can be picked by the ECG tracing.Hence option E is correct.
62. Upward movement away from the baseline in ECG tracing is known as positive deflection. Hence option C is correct.
63. A period of time between two points are events on the ecg tracing is known as interval. Hence Option E is correct.
64. All statements regarding the P- wave is correct. Hence option E is correct.
65. P waves represents atrial depolarization. Option D is correct.
66. Option E is correct as during QRS complex ventricular depolarization (major) and atrial repolartization occurs (minor).
67. Option D is correct
