SUMMARY
STUDYING OF THE PREVALENCE OF DIPPER AND NON-DIPPER BY USING

24 HOUR AMBULATORY BLOOD PRESSURE MONITORING (ABPM)

Objectives: To determine the prevalence of dipper and non-dipper by using 24 hour
ambulatory blood pressure monitoring (ABPM) and to assess the correlation between target
organ damage with white coat hypertension and essential hypertension.
Patients and method: Data from 60 hypertension patients in cluding 38 males and 22

used for the measurement blood pressure with the program 30 minutes per time and the
assessment of the changes in left ventricular structure by ECG and Echocardiography.
Results: - White coat hypertension group: The prevalence of dipper was 43,75% and non-

Conclusions: By using the 24 hour ambulatory blood pressure monitoring (ABPM) we can
detect the dipper and non-dipper phenomenon.
