Answer: Guidelines
◉ Required when general practitioner sends pt to a specialist
Answer: Method of referral
◉ The shallow wave that follows the T wave represents Answer:
Late ventricular repolarization
◉ Rhythm indicated by absence of/or inverted P waves Answer:
Junctional
◉ Inferior wall MI is shown in what leads Answer: II, III, AVF
,◉ Leads 1 and AVL show broken recording, you should Answer:
Check Left Arm
◉ Three lead EKG monitor Answer: I, II, III
◉ Why increase the speed of the EKG Answer: Increase speed
widens wave forms
◉ Placement of leads V1-V6 is important to diagnose Answer: Left
ventricular
◉ Why place V3 on right side of chest on an infant Answer: To
prevent crowding of the leads

◉ Calculating the atrial rate would be Answer: The p-p big box
method
◉ The PR interval is measured from Answer: The beginning of the P
wave to the beginning of QRS complex
