KAISER EKG EXAM A
On your patient's 12-lead EKG, Lead I's waves and complexes are completely negative. AVR's
waves and complexes are completely positive. The most likely cause of this is __________.
- axis deviation from ventricular tachycardia
- right and left arm leads inadvertently reversed
- dextrocardia
- axis deviation from an MI - ANSWER-right and left arm leads inadvertently reversed
+20mV is the ___________.
- Trans-membrane potential at the conclusion of phase 3 of the action potential
- Trans-membrane potential at the beginning of cardiac rest
- Trans-membrane potential at the conclusion of phase 0 of the action potential
- Resting trans-membrane potential - ANSWER-Trans-membrane potential at the conclusion of
phase 0 of the action potential
Which of the following statements correctly describes the relative refractory period?
1
,Page 2 of 178
- It is the period in which even a weak impulse can cause another depolarization.
- It is the period in which only a strong impulse can cause another depolarization.
- It is the period in which the heart function stops temporarily to allow impulse transmission to
occur.
- It is the period in which no impulses at all can cause another depolarization. - ANSWER-It is
the period in which only a strong impulse can cause another depolarization.
