Preliminary evaluation in clinical applications of frequency spectrum electrocardiogram

A series of 310 patients (207 male, 103 female, age ranged 40–74) examined with the frequency spectrum electrocardiograph (FCG) are analyzed to evaluate the clinical significance and problems correlating to the static electrocardiogram (ECG) from 1989 to 1991 in our hospital. On examination, a BIE-2 FCG was used. After FCG scanning, coronary heart disease numbered 92, acute and chronic myocardial infarction 20, angina pectoris 37, myocardiopathy 18, neurosis 56, carbon monoxide (CO) poisoning 17, thyroidism 9 and congenital heart disease 2. The positive index compatibility of coronary heart disease by FCG was 98%, which was higher than that by ECG simultaneously. It has been noticed that FCG provides special effects in diagnosing early coronary disease, differentiating disorders of nervous regulation and dysfunction of internal secretions, finding out the extent of myocardial injuries in patients with CO poisoning, detecting nervous disturbance and unknown aged myocardiel lesions, hence the value of FCG analysis is increasingly enhanced clinically compared with ECG. FCG also suggests some changes such as palpitation, chest depression and angina even though ECG is normal.
