In order to analyse the dynamics of blood pressure measured in periods shorter than a week, we evaluated the results of measurements in a 68-year-old man with benign prostatic hypertrophy and hypertension. During the period of investigation between September and November 1999, he changed his drinking habits and the time of Hytrin intake. In three 7-day periods, he monitored his blood pressure and heart rate around the clock. The results showed that alcohol consumption was related to an increase in circadian-hyper-amplitude-tension regardless of medication.
