Features of Premature Atrial Contraction (PAC).
|
- p wave looks different than others
- irregular rhythm - nomal QRS interval |
|
Interpret this ECG.
|
PAC on 4th beat
- p wave smaller |
|
Interpret the these 2 ECGs.
|
Top: PAC on 2nd and 6th beat
- different p wave Bottom: PAC with block on 2nd and 6th beats. - blocked p wave hidden in the T wave of preceding beat. - p wave fired during ERP. |
|
Interpret this ECG.
|
PAC: atrial bigeminy
- 2 beats repeating - regularly irregular rhythm - T wave looks different: p wave buried in it |
|
Features of ectopic atrial tachycardia.
|
- initiated with PAC
- paroxysmal |
|
How is ectopic atrial tachycardia different from sinus tachycardia?
|
ectopic atrial tachycardia: paroxysmal
sinus tachycardia: HR starts slow, goes up, takes awhile to come back down. |
|
Interpret this ECG.
|
Atrial tachycardia (SVT)
- HR between 150 and 250 - different p wave |
|
Features of wandering atrial pacemaker (WAP).
|
|
|
Features of multifocal atrial tachycardia (MAT).
|
- WAP that is fast
|
|
Interpret these ECGs.
|
MAT
- at least 3 different looking p wave - rate is over 100/min |
|
Features of atrial flutter.
|
|
|
Interpret this ECG.
|
Atrial flutter 4:1 block
- always even numer block - saw tooth appearance |
|
Interpret this ECG.
|
Atrial flutter 2:1 block
- ventricular rate of 150 |
|
Features of atrial fibrillation.
|
- atrial whiggles
- most common in elderly |
|
Interpret this ECG.
|
Atrial fibrillation
|
|
Features of junctional premature contraction (JPC).
|
- no p wave or

Features of Premature Ventricular Contraction (PVC).
|
- wide RR interval: 2x normal
- compensatory pause |
|
Interpret this ECG.
|
PVC: ventricular bigeminy
|
|
Features of ventricular tachycardia.
|
- lethal
- atria and ventricles beating independently. |
|
Interpret this ECG.
|
VT
|
|
Features of accelerated idioventricular rhythm.
|
- slow VT
- well tolerated - rate by purkinje fiber |
|
Features of Torsade de pointes.
|
- polymorphic VT.
|
|
Interpret this ECG.
|
Torsade de pointes.
|
|
Features of ventricular fibrillation.
