Sinus Tachycardia
|
100-150
|
|
|
Atrial tachycardia
|
- p waves may be buried in T
- 150-250 BPM |
|
|
SVT
|
-interchangeable with atrial tachy
|
|
|
A fib
|
- no distinguishable p waves
- irregular but normal QRS |
|
|
Junctional
|
- normal QRS
- P waves not present, inverted, or late - 40-60 impulse comes from AV node |
|
|
Accelerated junctional
|
- 60-100
|
|
|
PJC
|
- p wave not present, inverted
|
|
|
PVC
|
- wide QRS
- no P wave - unifocal or multifocal |
|
|
V couplet/ V bigeminy
|
- 2 PVCs back to back
- PVC every other beat |
|
|
Idioventricular
|
- wide QRS
- no p waves - 20-40 BPM - regular ventricular beats |
|
|
Accelerated idioventricular
|
- 40-100 BPM?
|
|
|
V tachycardia
|
- wide QRS, but regular
- no p waves - non-sustained/continuous - 100-250 BPM |
|
|
V fib
|
- chaotic baseline with no identifiable waveforms
- >350 BPM |
|
|
1st degree AV block
|
- prolonged PR interval (greater than .2 sec)
|
|
|
2nd degree type I AV block
|
- PR gets progressively longer and drops a complex
|
|
|
2nd degree type II AV block
|
- PR doesn't change (continuous)
- reg and normal QRS - multiple and regular p waves (march out) |
|
|
3rd degree AV block
|
- random PR interval
- multiple P waves - p and QRS march out, but separately |
|
|
RBBB
|
- wide QRS complex in all leads
- Rabbit ears in V1 and V2 |
|
|
LBBB
|
- wide QRS in all leads
- rabbit ears in V5 and V6 |
|
|
MI (3 phases)
|
1) acute injury/MI = ST elevation
2) old MI= significant Q waves (more than 1/3 of QRS) 3) Ischemia = T wave inversion - must be in at least two leads? |
|

|
V1, V2, V3, V4
|
|
|
