title: [The problem of indexation of left ventricular myocardial mass by body size in obese patients].
abstract: OBJECTIVE
  To assess efficacy of different ECG-criteria of left ventricular myocardial hypertrophy (LVH) in hypertensive patients as regards body mass (obesity).
  
  
  METHODS
  Data on 100 patients (42 males and 58 females, age 19-79 years) with diagnosis of hypertension of the first-second degree were analysed. ECG was registered in 12 leads. LVH was determined by ECG by the following criteria: Sokolov-Lion (S-L): Sv1+Rv5(v6) > 35 mm; Cornell voltage (Crn-V): R avL+Sv3 > 28 mm (> 20 mm for women); Cornell product (Crn-P). According to the body mass the patients were divided into 3 groups: with normal weight, overweight and obesity. Crn = P criterion was most sensitive in all the three groups.
  
  
  RESULTS
  In the groups sensitivity of ECG criteria depends on several factors: on the method of indexation and on the gender and body mass index.
  
  
  CONCLUSIONS
  Informative value of ECG criteria of LVH depends on the method of indexation and on the amount of the excessive body mass.
