What is the best method for assessing blood pressure in a newly diagnosed hypertensive patient?

Assessing blood pressure in both arms is considered the best method for a newly diagnosed hypertensive patient because it helps to identify any significant discrepancies between the two arms, which can indicate underlying vascular issues. A notable difference in blood pressure readings can be associated with conditions such as subclavian artery stenosis or other cardiovascular problems, making it essential to establish a baseline for both arms.

Additionally, this method is a standard practice in hypertension management to ensure an accurate assessment, especially before initiating treatment. While taking pressure in different positions—such as sitting, standing, or supine—can provide useful information about orthostatic hypotension, the initial measurement in both arms directly addresses the condition being investigated (hypertension) and potential comorbidities. It is also advisable to avoid measuring blood pressure immediately after exercise due to the temporary elevation that occurs post-activity, which may not reflect the patient's baseline status.
