The authors examine the behaviour of electric systole during @entity10129 treatment using doses of at least 10 mg/die in association with modifications of @entity63 signs recorded using surface ECG in a series of 70 elderly @entity1 . @entity1 were subdivided into three groups according to the results obtained from a comparison of real electric systole ( @entity1162 ) with that corrected for ventricular frequency (Qtc), as well as the difference expressed in mean values (VM). 1) @entity1 with elongated @entity1162 . Following @entity10129 treatment this group showed a mean elongation of electric systole of 0.393" +/- 0.025 with a R correlation index between electric systoles before and after treatment of 0.633" which expresses the amplitude of the elongation for each starting @entity1162 unit (p < 0.001). The mean value in the two conditions increased from -1.381 +/- 2.111 contraction units to 3.568 +/- 2.697 elongation units and mean deviation was 4.886 +/- 2.170 units with an absolute value of 211.0 units which expresses the elongation of the electric systole in the overall sample compared to @entity460 antagonists as an iatrogenic phenomenon. @entity63 signs improved or disappeared in 40 out of 44 cases (90.91%) for the T wave and in 36 out of 41 cases (87.80%) for the ST tract. 2) @entity1 with normalised @entity1162 . In 6 cases which showed elongated pretreatment electric systole, it was observed that values became normal passing from a mean of 0.390" +/- 0.40 to 0.377" +/- 0.053. Mean deviation diminished from 3.833 +/- 0.983 units to 1.333 +/- 1.211 units with statistical significance only for paired data in 2 groups (p < 0.001), without correlation.(ABSTRACT TRUNCATED AT 250 WORDS)
