I would not trust your Apple watch to give you accurate BP numbers. I have used those type devices in the past and found numbers can be way off.

You just saw a cardiologist. What was your BP at your cardiologist visit? That would give you a more accurate rate.

I would buy a home BP monitor. Get a good one. I use one all the time that is automatic and very quick. It is very accurate. You can even bring your BP monitor into your doctor's office and have them to a BP test and then do one with yours. They should be close.

If you have not exercised in over 12 months both your pulse rate and BP will probably be high. You mentioned a number 40. Was this systolic or diastolic? If systolic a dangerous level. I don't think it was accurate number. And if distolic could would most often cause dizzeness. This is why you need to have checked in doctors office and if you want to monitor get a more accurate device that has the cuff over the arm.
