Multi focal pwaves >100bpm Rhythm irregular PRI variable QRS is normal
3
Q
Atrial Tachycardia
A
Single atrial Foci rapidly firing Pwaves HIDDEN 140-250 bpm PRI IND Rhythm regular usually QRS normal May be “paroxysmal” (sudden onset)

A
Rapid identical undulating waves Called flutter waves instead p Saw tooth PRI IND QRS normal Rhythm regular/ irregular Named: Atrial flutter with Fwave:QRS AV conduction Atrial flutter with variable AV conduction
5
Q
