12 FCG Power Spectra with Ischemic Diagnostic Indexes reading

12-Lead Power Spectrum - 12 power spectra, one for each of 12 leads, on one page; - Each power spectrum lists five (5) ischemic diagnostic indexes, H, N, B, A, E.

DIAGNOSTIC INDEXES FROM FCG POWER SPECTRUM

Positive (+) Index H - Insufficient myocardial energy caused by lack of blood supply (Early Ischemia)

N - Myocardium injuries

B - Ventricular hypertrophy or Ischemic Cardiomyopathy

A - Myocardial Ischemia (more advance stage)

E - Myocardial compensation has set in for one or more years

CAD LOCATION

CS-100 compiles the diagnostic indexes from the 12-lead power spectra and graphically suggests the presence and location of Coronary Artery Disease (“CAD”), if any.

DiagnosticLine →

(1) Look for three (3) consecutive columns over the diagnostic line (column with the red color), the lead(s) with the highest column suggests the anatomical area of a heart where CAD locates.(2) I, aVL, V5 and V6 – Lateral wall of the left ventricular(3) V1 and V2 – septal wall of the left ventricular(4) II, III and aVF – inferior wall of the left ventricular

Frontal Plane Leads Horizontal Plane Leads

TWO LEADS ( II & V5) Positive (+) Index A. PHASE ANGLE SHIFT (one index) - P (1)Over one unit zone - Poor flow to the heart, indicative of an early stage of ischemia.

(2)Greater deviations and fluctuations (axis deviation) - Poor or defective conduction function, poor blood circulation and change of blood dynamics.

(3)Severe deviation - Left bundle branch conduction block.

(4)Sharp oscillation - Time delay caused by CAD of coronary artery blockage, poor blood circulation, or myocardial infarction.

TWO LEADS ( II & V5) Positive (+) Index

B. IMPULSE RESPONSE (four indexes) f - Conduction block caused by CAD or conduction blockage. Diagnostic Suggestion – With (+) reading of H, A and A5, it suggests Myocardial Infarction (MI).

M - Poor conduction, increased in compliance. Diagnostic Suggestion - left ventricular malfunction.

R - Unstable cardiac electricity prior to the formation of MI, Increase in localized ischemia or MI. Diagnostic Suggestion - early detection of MI

C - Unstable latent cardiac electrical activities at the beginning of contraction.

Diagnostic Suggestion - detection of latent arrhythmia.
