EKG 03-Answer

  • Rate: 2 beats(1 cuplet)/1.44 seconds, 42 bpm (Second beat of the couplet is so early, there is no time to fill and therefore probably won’t produce a pulse wave)
  • Rhythm: Bigemini
  • Axis: +50
  • Intervals: Beat 1 PR=150ms, QRS 70/100ms
  • Morphology: First narrow, #2 aberrant (Notice extra P wave after each couplet.  Probably originating from SA node but blocked by second premature ventricular beat of couplet)
  • ST Segments: No ischemic changes,#2 C/W aberrant beats
  • T Waves: First no ischemia, #2 C/W aberrancy
