ECG Reading Simple Tips:
1. Sinus Bradycardia – slow beat <60 beats per minute or slower
2. Atrio ventricular Junctional Rythm or Idionodal rythm – 40 – 60 beats per minute,
absent or retrograde P wave
3. Idioventricular rythm – 20-40 beats per minute
P waves generally absent, wide QRS (more than .12 msec or 3 small boxes wide)
4. Sinoatrial exit block – failure of transmission from SA node to atrium
Absent P wave; equal R-R cycles, no QRS
AV BLOCKS
5. First degree AV Block – prolonged P-R interval (about 5 small squares)
6. Second degree AV Block Type I – progressive prolonged P-R interval then drop beat
7. Second degree AV Block Type II – Normal then sudden drop, no prolongation of P-R
8. Second degree AV Block 2:1 – 2 P waves and 1 QRS
9. High grade AV Block – 3 P-waves and 1 QRS
10. Third degree/Complete AV Block – P-waves and QRS has no association with each other, P-R interval varies
