Table 1A. Blood pressure and serum electrolytes values in the proband.
Blood pressure of a 34-month-old FHHt patient prior to his diagnosis and thiazide diuretics (Diuril) administration were measured three separate times during the inpatient admission at the NIH’s Clinical Center through the Undiagnosed Diseases Program (UDP). These values were averaged and compared to reference pediatric blood pressure ranges, from 90th (pre-hypertensive) to 99th (stage II hypertension) percentiles normalized by height (5th percentile) and age (3 years old); results reveal severe pediatric hypertension in the patient. Reference ranges were drawn from the National Heart, Lung and Blood Institute (NHLBI/NIH) Boys and Girls Blood Pressure Levels Guidelines.
| Blood Pressure | Proband | 90–99% Reference Range |
|---|---|---|
| Systolic (mmHg) | 125±6 | 100–111 |
| Diastolic (mmHg) | 73±10 | 59–71 |
