I thought I'd post this here to see if anyone can advise me. Last year, my Mom gave me an in-home blood pressure monitor, because like her, I have high blood pressure. Lately, it's been somewhat intractable, despite the fact that I am now on two different medicines (a recent development my Primary Care Physician is trying to address). Doctor wants me to check my pressure once a day, which I've been doing. The numbers have not looked very good for the past week or so. Just now, it was 160 over 100. Heart rate 98. But the machine also beeped a warning at me for the first time. It said, "irregular heartbeat detected". That gave me somewhat of an uneasy feeling. What exactly does that mean in light of the elevated pressure reading, and should I be very concerned about this---enough to seek medical attention on a Friday night? I'm hoping one of our resident MDs will be able to advise me on this. Thanks.
