When you are at rest in a warm bed, arteries dilate and blood pressure tends to be low. When you stand up, your body elevates blood pressure to be sure your brain is perfused so you don’t black out. Getting out of bed in a cold room could cause an increase in pressure. How high does it get when you stand up? Does it then return to normal? Is your blood pressure cuff accurate? Discuss these questions with your doctor.

A: The pacemaker or its wires may stand out due to your having little body fat or because of where the pacemaker was implanted. I would not worry about it as long as the skin over the wires and the pacemaker does not get red and sore and the area does not get rubbed or bumped often. While the implant can
be revised and buried deeper, it is best to “leave well enough alone.” Any revision carries some risk, particularly of infection. So avoid that if possible. The best news is that the pacemaker is preventing your passing-out spells.
