What to do if I have pacemaker for low heart rate today I'm runnin high 90's BP 133/ 91?

Pacemaker. The pacemaker is likely programmed to stimulate your heart if your intrinsic rate falls below a programmed rate like 60 or 70 beats a minute. If your heart is going 90 on its own, the pacer is just monitoring to see how fast the heart is going and will 'kick in' if your heart slows to under the programmed rate.
