If your heart rate is 150-160 during measuring, it's obvious that your slightly elevated blood pressure may be caused by anxiety during measuring.
Please ask your doctor for a 24 hour monitoring to find your "true" blood pressure. Everyone will have an elevated blood pressure with a heart rate of 160, and maybe you should treat the root (anxiety) rather than your symptoms (elevated blood pressure)?
I'm not sure I've had the same question myself, would love to know the answer. My nurse told me the digital ones can hear with better accuracy than the doctor can. I have also heard the manual ones are more accurate so idk. I have hypertension as well I'm 22 and pretty active and normal weight mine runs about 150/80 but manuals sometimes give me in the 130's/80 I'm currently takin Bp meds (losartan 50mg/Hctz 12.5mg) worked for a month now it's spiraling in the 150's consistanly. I also have low pulse 40's while resting so I gotta take certain Bp meds that don't lower it more. It's ***** but hopefully we get rid of this hypertension !
