Depolarization Analysis Decision Categories And Rules - Innomed Medical HS112 C-1 User Manual

20.2. Depolarization analysis decision categories and rules

The two-stepped process includes statistical method, partial decision tree type algorithm.
Int he first step the program decides the most probable illness class based ont he database created from several thousand
measurements. Int he second step it checks, this based on the required conditions, using traditional physician logic.
The rest of the document summarizes the checking rules.
NORMAL DEPOLARIZATION
QRS complex narrower than 110ms, negative hypertrophia test. No wide Q on leads V5 and aVF, R-wave on V2.
PATHOLOGICAL Q ON V2,V3 (ANTEROSEPTALIS MYOCARDIALIS INFARCTUS)
QRS complex narrower than 110ms, Q-wave width on V2-V3 greater than or equal to 40ms.
PATHOLOGICAL Q ON I, V5, V6 (LATERALIS MYOCARDIALIS INFARCTUS)
QRS width cannot exceed 110ms and the limb I. and V5-V6 leads' Q timeperiod has to reach 30ms.
PATHOLOGICAL Q ON I, V2, V3,V6 (EXTENSIVE ANTERIOR MYOCARDIALIS INFARCTUS)
Its conditions are depolarization width shorter than the above QRS width. Q on limb lead I. must exceed 25ms, on chest
leads 30 ms.
PATHOLOGICAL Q ON II, III, aVF (INFERIOR MYOCARDIALIS INFARCTUS)
QRS cannot exceed 110ms, Q on lead II. must reach 25ms, 30ms on leads III. and aVF.
PATHOLOGICAL R ON V1,V2 (POSTEROBASALIS MYOCARDIALIS INFARCTUS)
QRS width must be under 110ms. The R-wave measured on V1 must exceed 4mm and at the same time be greater than
the S-wave measured on V1. On lead V2 the R-wave must be 100% greater (double) than the S-wave.
PATHOLOGICAL Q ON II, III, aVF AND PATHOLOGICAL R ON V1,V2 (INFERIOR+PBMI)
In this class the conditions of the previous two classes must be met.
PATHOLOGICAL Q ON II, III, aVF,V2,V5 (ANTERO-INFERIOR MYOCARDIALIS INFARCTUS)
QRS under 110ms, and the inferior and anterior infarctus conditions are met.
PATHOLOGICAL Q ON LEADS V2,V3,V4 (ANTERIOR MYOCARDIALIS INFARCTUS)
QRS width under 110ms, Q width must exceed 40ms.
PATHOLOGICAL RS-WAVE ON V2-V4 (ANTERIOR MYOCARDIALIS INFARCTUS)
Its condition is QRS under 110ms and R-wave not exceeding 2mm on leads V2-V4. In reality this is the likeness of
anterior infarctus in regenerating state.
PATHOLOGICAL RS-WAVE ON V2-V3 (ANTERO-SEPTALIS M.I.)
Its conditions is QRS under 110ms and R-wave not exceeding 2mm on leads V2-V3. This picture corresponds to
anteroseptialis infarctus regeneration.
PATHOLOGICAL QRS COMPLEX ON LEAD V2
This diagnosis is received if abnormal Q or abnormal R/S ratio is realized only on lead V2.
PATHOLOGICAL Q-WAVE ON LEAD V5
Those patients for whom lateral M.I. condition – Q not reaching the required width on V6 – is not met completely are
placed here.
