Non-invasive assessment of 42 cases of dilated cardiomyopathy [idiopathic]

ABSTRACT

Over the past thirty years the new techniques of biotechnology have touched most of the recalcitrant problems in the cardiac diagnosis. Non-invasive assessment of 42 cases of Idiopathic Dilated Cardiomyopathy by using ECG, PCG, ACG and Carotid pulse wave, are presented here. The diagnosis of Idiopathic dilated cardiomyopathy was done by exclusion. Endomycardial biopsies and Angio studies of these cases were not be done. The age varied from 3-50 yrs with mean of 24 +/- 14. 3 SD and male female ratio was 31. STIs show incease in CMI [Mean-49 +/- 10 SD], QMl [Mean-91 +/- 10 SD] PEP/LVET ratio [Mean - 66 +/- 14 SD], C-Ml/M1-E% [Mean-159 +/- 55 SD]. STIs shows decrease in Ml-E [Mean 34 +/- 13 SD], LVET [Mean-197 +/- 38 SD], EF [Mean-36 +/- 13 SD] and Ml-A2 [Mean-231 +/- SD] with no change in Q-A2 interval. DTIs show increase in A2-MI [Mean-278 +/- 26 SD], OF/EO ratio% - [Mean 27 +/- 18 SD], CMl-OF [Mean 8 +/- 16 SD], OF/SFW% [Mean-133 +/- 46 SD] and a/EO% - [Mean-18 +/- 9 SD]. ACG shows early change of slope, prominent F-wave, sharp E-point, LSB and increase in 1/2 time RR%. Carotid pulse wave shows prominent dicrotic wave, normal 1/2 time RR% and lower normal rate of rise
