The fifth group of arrhythmia waveforms is the conduction arrhythmia group—a group
that consists of various conduction defects.
To select this group, press <F1>-COND from page 2 of the ARRHYTHMIAS MENU for
the following two display pages of seven conduction arrhythmia waveforms:

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.
