Correct Answer: Muscle soreness due to activity performed during the test. Which electrodes can a telemetry monitoring device have to perform the procedure? Correct Answer: RA, LL, LA, RL, V1 Which electrodes are most commonly selected for 3 Electrode EKG? Correct Answer: RA, RL, LL Where would the V3 Electrode be place on a left sided 12 lead EKG? Correct Answer: Directly between V2 and V4 electrode The EKG machine records which activity of the heart during Holter Monitoring? Correct Answer: Electrical activity of the heart How do you calculate the heart rate max? Correct Answer: 220 minus age What would the heart rate max of a 37 year old woman be? Correct Answer: 183 When is Bundle Branch Block represented? Correct Answer: The QRS complex is more than 0.10 second with a notched appearance. What would a significant Q Wave be a diagnostic indicator of? Correct Answer: Infarction Particularly in Lead V1, V2, V3 and V4, a "T" wave inversion is a very important diagnostic and could be indicating what?

Correct Answer: QT Interval Performing a EKG on a patient who had a heart transplant has 2 Sino Atrial nodes each producing what and how many? Correct Answer: 2; PN-Native P Wave and Pd Donor P Wave What would be the heart rate of four large boxes between 2 P waves? Correct Answer: 75 BPM What would be the heart rate of 6 large boxes between 2 R waves? Correct Answer: 50 BPM While performing an EKG on a patient with a hairy chest, what would be the most appropriate action taken by the EKG technician? Correct Answer: To shave the area where the electroleads will be placed. To record the electrical activity of the heart, how many hours will the holter monitoring device be placed on the patients chest? Correct Answer: 24-48 hours On a EKG with Lead I, what area of the heart can be viewed? Correct Answer: Lateral View What is the result of a normal Q wave? Correct Answer: Ventricular depolarization The period for the electrical impulse to travel from SA Node to bundle of His is measured by what Interval? Correct Answer: P-R Interval What does a normal QRS complex have and how many? Correct Answer: 3 Waves What would result in a wandering baseline on a EKG graph? Correct Answer: Thoracic movement with respiration On an EKG graph, what would result in a 60-cycle interference? Correct Answer: Electrical interference from other equipment in the room.
