I'm not blessed with good BP genes, lifelong issue. i too take lisinopril and I monitor my BP every day -- well most every day -- usually in the morning, taking the average of five readings. The past few months I started taking my BP after a ride and noticed a substantial drop in BP for multiple hours after a ride. For example, my BP is usually about 125/70 and after a ride it will drop to 110/60 or lower. I asked my cardiologist about this and he says it is not unusual for this to happen after exercise. I don't average those readings into my daily BP recordings!

I have been using an Omron 7xx for multiple years and the inconsistency of the readings always drives me bonkers, which is why I take five readings and average the most consistent ones. I took the device into one of my cardio appointments a few years ago to compare with the sphygmomanometer reads it mine unit reads a bit high, but our of five readings there can be a 15-20% difference between the high and low systolic pressure. I am shopping for a sphymamonometer unit to replace the Omron in hopes of getting more consistent readings.
