An electrocardiogram is limited to measuring electrical activity of the heart, so heart rate cannot be determined.True false question.TrueFalse

Heart rate is not a good indicator of the intensity of an exercise. True False

8. Any organized electrical activity observed on an ECG or cardiac monitor in a individual with no palpable pulse is referred to as:A Ventricular fibrillationB PEA (pulseless electrical activity)C Ventricular tachycardia without pulsesD Asystole
