Objective:
Hypertension is unusual in young adults. Malingering hypertension is clinically suspected when there is a potential external secondary gain, absence of patient cooperation during diagnostic evaluation and a lack of response to antihypertensive treatment. The aim of this study was to investigate the possibility that abnormal ambulatory blood pressure patterns may be indicative of malingering hypertension rather than hypertension itself.
Methods:
Young adults aged 19-20 years, referred for evaluation of high ambulatory blood pressure, underwent a detailed clinical interview, physical examination, and both in-clinic and 24-h ambulatory blood pressure monitoring. Blood pressure patterns were compared in patients with normal blood pressure values, essential hypertension, or suspected malingering hypertension (20 in each group).
Results:
Both the suspected malingering hypertension and the essential hypertension group had higher blood pressure values during day and night than the normotensive group. Compared with essential hypertension subjects, the malingering hypertension group showed a greater fluctuation of blood pressure values, lower total percentage of time of abnormally high systolic blood pressure values during the day (41.9+/-16 vs. 65.9+/-12.4, P<0.001) and night (41.8+/-25 vs. 69+/-22.4, P=0.001), and higher maximum heart rate values during the day (132.8+/-15.2 vs. 115.1+/-11.6, P<0.001) and night (93.4+/-19.2 vs. 80.5+/-13.2, P=0.028).
Conclusion:
Patients with malingering hypertension form a distinct clinical group. We suggest that the diagnostician rely on clinical suspicion, fulfillment of our proposed criteria, and distinguishable characteristics of blood pressure patterns. Successful recognition of malingering hypertension can spare patients from unnecessary medical and surgical treatments.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Errors occurring during blood pressure monitoring
Several factors...
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
Alterations in Blood Pressure
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart beats)...
