In this first episode of our two part series on pediatric hypertension, we talk to Dr. Tammy Brady, a pediatric nephrologist at Johns Hopkins, and Dr. Joshua Samuels, both a pediatric and adult nephrologist at University of Texas Houston. In this episode they review ambulatory blood pressure monitors, the basis for our standards for diagnosing pediatric hypertension, the pathophysiology behind obesity increasing the risk of developing hypertension, and ensuring blood pressure is accurately measured.
