- Absent P-wave
- Irregular Pulse
- HR > 100-200 bpm
Atrial Fibrillation
*Bizarre QRS.
-Sometimes looks like an upside down QRS
Premature Ventricular Complexes (PVC)
- HR >100bpm
- Large, wide, undulating waves
- P waves are not associated w/ the QRS complex
Ventricular Tachycardia - P wave is normal *** can and often does outnumber QRS complex
- PR interval is normal or prolonged (>0.20 sec)
- QRS complex will be normal or wide
2nd Degree Heart Block (Type II) - P wave is normal
- PR interval is progressively longer (>0.20 sec)
- ***QRS complex will usually be normal (0.06-0.10 sec) UNTIL IT IS MISSED, then the cycle repeated
2nd Degree Heart Block (Type 1) - P – wave is normal
- *** PR interval prolonged (>0.20 sec)
- QRS will be normal (0.06-0.10 sec)
1st Degree Heart Block - Quivering and lack of effective contraction
- ECG is rapid and erratic w/ no identifiable QRS complex
Ventricular Fibrillation - Rapid HR
- 240-350 bpm w/ a saw tooth pattern
- Type I 240-350
- Type II >350
Atrial Flutter
