, 1. Atrial Flutter -has a "saw tooth or picket fence"
atrial pattern (no P waves, F-waves in stead that
may be in a ratio) between the QRS complexes.
2. Atrial Fibrillation-Has "chaotic" atrial electrical
activ- ity (no P waves, f-waves instead) with
irregular R-R intervals.
3. PJCs cause the rhythm to be irregular. The P wave
is inverted if it can be seen. It may occur before,
during or after the QRS. The P wave will not be seen
due to its low voltage.
4. Junctional Rhythm may have an inverted or absent P
wave. The P wave may occur before, during or after
the QRS complex. The rate for this rhythm is 40-60
bpm.
5. Accelerated Junctional Rhythm may have an
inverted or absent P wave. The P wave may occur
before, dur- ing or after the QRS complex. The rate
for this rhythm is 60-100 bpm.
6. Junctional Tachycardia Rhythm may have an
inverted or absent P wave. The P wave may occur
before, dur- ing or after the QRS complex. The rate
for this rhythm is 100-180 bpm
7. Supraventricular Tachycardia presents with a "nor-
mal-narrow" appearing QRS complex and a rate of
greater than 150 bpm. Remember for heart rates ap-
proaching 150 or higher, it will be very likely that the
P wave will be buried. Be prepared to increase the
paper speed for this rhythm.
8. First Degree AV Block, the PR interval is constant
and measures greater than 0.20 second.
9. Second Degree AV Blocok Mobitz I (Wenkebach)
