title: [Regulatory-adaptive abilities of hypertensive patients treated with lisinopril and atenolol].
abstract: OBJECTIVE
  To examine regulatory-adaptive possibilities of hypertensive patients treated with lisinopril and atenolol.
  
  
  METHODS
  Monotherapies with lisinopril and atenolol were compared in relation to effect on arterial pressure and parameters of cardiac-respiratory synchronism after a single and 5-week intake in 37 patients.
  
  
  RESULTS
  Lisinopril increased in 19 patients the range of synchronization by 28.5% (p < 0.05) after a single dose and by 40% (p < 0.001) after 5-week treatment. Atenolol had an adequate hypotensive effect in 18 patients but promoted a decrease of range sychnonization by 41% (p < 0.00001) after a single intake.
  
  
  CONCLUSIONS
  Hypotensive drugs should be studied for effects on regulatory-adaptive ability of the organism.
