The fifth group of arrhythmia waveforms is the conduction arrhythmia group—a group
that consists of various conduction defects.
To select this group, press
the following two display pages of seven conduction arrhythmia waveforms:

Selections Descriptions
nsr
Normal sinus rhythm. Provides a convenient way to return to normal
sinus rhythm.
1 °bk
First degree A-V block. Normal sinus rhythm except with long PR
interval of 0.25 seconds.
2 °b1
Second degree A-V block, type 1, Wenckebach. Increasing PR
interval from 0.22 to 0.47 seconds, followed by a P-wave only with no
QRS response, repeated. P-waves at 80 BPM.
2 °b2
Second degree A-V block, type 2. Waveform similar to right bundle
branch block except PR interval is 0.25 seconds. Eighteen beats at 80
BPM followed by two missed beats; repeated.
3 °bk
Third degree A-V block. Normal sinus rhythm waveform except with
a P-wave rate of 80 BPM and a QRS rate of 30 BPM running
independently of each other.
rbbb
Right bundle branch block. Wide QRS complexes. An 80 BPM rate
with a PR interval of 0.16 seconds.
lbbb
Left bundle branch block. Wide QRS complexes. An 80 BPM rate
with a PR interval of 0.16 seconds.
