Nursing Points

General

12 Lead EKG: Leads 1, 2, 3, aVL, & aVF
1. “+” or “-” regarding electrical charge of heart
  1. Positive lead = left arm, left leg
  2. Negative lead = arm
2. Lead monitoring
  1. Lead 1, aVL -> view inferior wall of heart
3. To read a hemi-block
  1. Electrical current goes through L bundle first -> through ventricular anterior septal wall -> then through right bundle
  2. ‘Deviations’ of the direction of electrical current
    1. Right axis deviation = S wave dips down far in Lead 1 and aVL
    2. Left axis deviation = S wave dips down far in Lead 2, 3, and aVF
