PG  - 360-7
AB  - Electro- and vectorcardiographic methods describe left ventricle increases only 
      when it has attained a significantly high magnitude, but even in such 
      circumstances the exactitude of such methods is substantially lower than that of 
      echocardiogram (ECHO). On the other hand, in comparison to other age groups, 
      there have been relatively few reports relating electrocardiogram (ECG), 
      vectorcardiogram (VCG) and ECHO with left ventricular mass (LVM) in healthy 
      elderly subjects where increases of the left ventricle mass, if present, would be 
      small or moderate. In this paper LVM as well as LVM index (iLVM) from a group of 
      healthy subjects belonging to a physical training program for elderly, was 
      studied by means of ECHO and computerized ECG and VCG. From ECG, voltage indexes 
      and other LVM associated parameters were extracted; from VCG, planar maximum 
      vectors, areas within VCG loops and maximal spatial magnitude of QRS (SM), were 
      measured. Results of LVM (221 +/- 37.9, g) were higher than figures reported for 
      others groups. Voltage indexes showed normal values, but QRS duration was 
      somewhat prolonged. The best simple linear regression, combining variables from 
      VCG and ECG was maximum horizontal vector (Vmax-Hor) vs Sokolow-Lyon index (SOK) 
      and combining ECHO with ECG or VCG, LVM vs Area inside horizontal loop (AreaHor). 
      A model for estimation of LVM from electrical variables was obtained by multiple 
      linear regression; combining five variables from ECG and VCG. The best model 
      included Sokolow-Lyon index and variables from horizontal and sagittal planes of 
      VCG and spatial magnitude of QRS: LVM = 4.8 SOK-186 VmaxHOR-80 VmaxSAG + 126SM + 
      340 AreaH + 175.(ABSTRACT TRUNCATED AT 250 WORDS)
