... lisiopril 20mg pm, HCTZ 12.5 am, plus 40 to 80 mg daily of propranolol and it's high still & erratic. I recently took a deep breath and held it while taking my last 2 BP readings and noticed that it went down significantly to 138/85. Could the high readings possibly be from my pulmonary hypertension? Last angiogram shown "pulmonary arterial tortuosity." Appreciate any help or advice! Thanks!
