Select an automatic home blood pressure monitor that is capable of measuring your heart rate. An automatic device measures your blood pressure with the push of a button (no need to manually pump the cuff to inflate it).
Second, get a cuff that will fit over your upper arm-not on your wrist and not on your finger.
Finally, the upper arm cuff should fit you well. Its common for people to buy a cuff thats too small. If youre not sure, measure your arm around the largest part. Anything over about 32 centimeters (12.6 inches) means you should use a large cuff.
