112 ENG - Version 2.1 – P/N 04130.2
Designation Explanation
R Excluded due to a too small/large distance to earlier or
following cycle. Measurement error possible!
V Excluded due to ECG complex being located too much
outside of the examined interval (P- or T-wave partially
missing)
Table 6-3 Criteria of the representative cycle
Conclusions about the rhythm of a recording of just 10 s length require an
analysis of every available ECG complex and every previous or following RR-
interval.
For the plausibility check of the conclusions about the rhythm and as an aid for
the quality check, the ECG measurement/interpretation program HES issues a
rhythm- and typing diagram that represents the cycle sequence of the ECG
complexes in an abbreviated form.
Each ECG complex is represented by a symbol. The distance between the
symbols represents - on a greater raster - the RR-interval.
Example 1:
+--+--+--+--+--+--+--+--+
Fig. 6-14 Rhythm- and typing diagram for a regular sinus rhythm
This representation means that 9 ECG complexes of the same morphology
have been found in the recorded ECG and have been averaged for a
"Representative cycle". The distance between the ECG complexes was roughly
the same (regular distance -).
Example 2:
+--+-2---+--+-2---+-P---+--+
Fig. 6-15 Rhythm- and typing diagram for a sinus rhythm with two
compensated ventricular and one compensated supraventricular
extrasystole
In this representation 10 ECG complexes have been found. The complexes 1, 2,
4, 5, 7, 9 and 10 represent the main type, from which the "Representative cycle"
for diagnosis has been averaged.
The ECG complexes number three and six ("2") deviate from the main type in
their QRS morphology and have a shortened distance to the previous complex
and a prolonged RR-interval to the following normal complex (+). This fact
indicates two monomorphous ventricular extrasystoles and the text message
should contain corresponding advice.
Complex number eight ("P") has a shortened distance to the previous complex
(+) and a prolonged distance to the following normal complex (+).
"P" means that only the P-wave, but not the QRS-T of the respective ECG
complex deviates from the normal cycle. In conjunction with the prematurity and
subsequent prolongation of the RR-interval, one concludes an atrial
extrasystole and expects corresponding advice in the text message.
