      urinary catecholamines.

AB  - Nine adult subjects with documented cardiac arrhythmia were studied during 4 
      nights of sleep in a laboratory. A sleep polygraph and single-channel 
      electrocardiogram were recorded continuously throughout each night. After the 1st 
      night's familiarization, the subjects were presented with 1 night each of 50 
      calibrated aircraft or truck noise events. One other night was noise-free. 
      Intervals containing noise and paired quiet intervals were examined for sleep 
      stage at interval onset, number of sleep stage changes and ventricular premature 
      contractions (VPCs). Overnight urinary catecholamines were also assayed. It was 
      found that noise increased the likelihood of arousal responses to the same extent 
      in all sleep stages (p < 0.05). Four subjects showed frequent VPCs during the 
      experiment. These VPCs were significantly related to sleep stage (p < 0.05) but 
      not to noise events. Excretion of urinary catecholamines did not differ between 
      noise and quiet nights.
