EKG

Abnormal looking P wave
P: QRS relationship 1:1
P wave of different shape than sinus P wave & PRI may vary from sinus P wave

HR: 160-250
P:QRS relationship 1:1 (however difficult/impossible to differentiate)
Regular rhythm
Onset and termination occur suddenly
May cause palpatations and lightheadedness

PRI - unable to determine because you don't know which flutter wave is conducted to the ventricle
P waves may have sawtooth configuration

PRI - n/a
Rhythm - irregular
Irregular baseline
Irregularly irregular
Recognizable QRS (unlike Vfib)

Ventricular rate: 40-60 (60-100 is accelerated junction rhythm)
P waves may precede, be hidden in or follow QRS; if visible they're always altered

Regular rhythm

QRS complexes of uniform shape but premature
P waves irregular with premature beat - it may precede, be hidden in, or follow QRS
Shortened PRi (<0.12)

What is the ventricular tachycardia rate?

Beat occurs premature
QRS complex wide & distorted. (>.10)
Rhythm irregular due to premature beat

PRi prolonged >0.20 secs

what block is it?

QRS becomes progressively longer til it is dropped
After dropped beat PRI is shorter
Vrate is irregular
Atrial rate is regular

Atrial rate regular
Vent rate slow
No relationship b/w P waves and QRS complexes
No constant PRI
QRS interval may
be normal or wide.
