Diffuse PR depressions (reciprocal elevation in avR)
Pericarditis
Notched j-point
Paricarditis
Low voltage
Percarditis
A really peaked T from the J-point
Hyperacute MI
AV Paced
A paced, V paced (dual all the time)
PV Paced
P sensed, V Paced
PR Paced
No intervention unless required
AR Pacing
Paces P wave only
A funky looking P-wave every beat over 100 BPM
Multifocal Atrial Tachycardia
A funky looking P-wave every beat under 100 BPM
Wandering Atrial Pacemaker
Besides MAT, and WAP, what else is irregularly irregular?
Atrial Fibrillation
Diffuse T wave inversions….think…
Ischemia (globally, hypoxia, etc)
PR > .20
First degree block
Progressively lengthening PR, then dropped QRS
Second Degree type 1 (Weckenbach)
Normal PR interval, with multiple isolated P waves between complexes
Second Degree type 2
What is the ventricular escape rate in 3rd degree block
30-45 bpm
