  • 1. A couple of years ago, I had a pacemaker put in. Now I am having some problems with dizzy spells. My doctor thinks these may be neurological and would like to do an MRI scan. However, he says that he can't because of my pacemaker. Is this a big problem? Is there anything that can be done about it?

  • 2. I had a pacemaker inserted a few years ago to control my heart rate. Recently, my doctor recommended that I have a magnetic resonance imaging (MRI) scan of my spine to determine the cause of my lower back pain. Is it safe for me to have the MRI?

  • 3. Ask the doctor. For several years now, my lower legs have been painful and somewhat swollen, especially at the end of the day. My doctor says that my veins are not getting the blood back to my heart like they used to, but that it is just part of aging (I am 72 years old). He tells me to put my feet up as much as possible, but that's not very practical when you have a lot to do! Isn't there anything else I could try?

  • 4. Ask the doctor. A year ago, my doctor recommended that I have a pacemaker because my pulse rate was too slow (38 on a monitor, 48 taken by hand). I did, and the rate of the pacemaker was set at 60. I am 90 years old, and my entire life my heart rate has been fortyish. Is my future affected by my pacemaker's timing?

  • 5. Ask the doctor. I am 73 years old and have had a heart murmur for years. Now my doctor tells me that I have moderate narrowing of my aortic valve. I feel perfectly fine, but he says I may need heart surgery some day. Is there anything I can do to avoid having surgery?

  • 6. By the way, doctor. I've had a pain in my shoulder for two weeks, which my doctor says is tendonitis of my rotator cuff. What can you tell me about this condition? I can't recall doing anything to cause the pain.

  • 7. My doctor says I have sick sinus syndrome. I was recently hospitalized because of runs of rapid heart rates. When they gave medications to make my heart slow down, it went too slowly. Finally, they put a pacemaker in me and now I take pills every day. Is all this necessary?

  • 8. Ask the doctor. The right ventricle bundle of nerves in my heart is blocked, and the doctor I went to did not seem concerned at all. Yet a friend of mine who had the same condition almost died when the left bundle shut down. He just happened to be in the hospital for another condition when it occurred, and they put a pacemaker in. He had some chest pain, but is otherwise OK. Do I need a pacemaker, too?

  • 9. Ask the doctor. I just got a pacemaker for a slow heartbeat. The idea that I am going to need to have the pacemaker changed when the battery runs out bothers me. Can I do anything to make my battery last longer?

  • 10. Recently, my pulse was 44, and at night when I sleep it drops into the 30s. I have had a low pulse rate for 40 years. My doctor thinks I need a pacemaker. Do you agree?

  • 11. On call. I developed severe ulcerative colitis in my late teens, and I had my entire colon and rectum removed at age 24. It was certainly worthwhile, since I adjusted easily and I've been healthy ever since. But now I'm 52, and I'm starting to think about prostate cancer. My doctor obviously can't do a rectal exam, and he doesn't want to do a PSA test because he says he won't be able to send me for a prostate biopsy if the test is high. Do I have any options?

  • 12. Ask the doctor. Last month you wrote about MRIs being bad for pacemakers and defibrillators. What about stents? They are metal, too. I had two stents put in a few months ago. Can I ever have an MRI?

  • 13. Ask the doctor. I have had dizzy spells every few weeks for years. My doctor has done a lot of tests, including a Holter monitor, but nothing has turned up. I am most concerned about whether I could be having heart-rhythm problems, but my Holter was apparently normal. Should I be undergoing other tests?

  • 14. Ask the doctor. I am 68 years old and had a heart attack last year. I think I am doing fine and passed my last exercise test with flying colors. But about a month ago I had a fainting spell, which occurred when I went to the bathroom after a big meal. In addition, I frequently feel lightheaded for a few seconds when I stand up. I think that problem has been there for years. Do you think these spells are related to my heart?

  • 15. Ask the doctor. I recently had a pacemaker implanted. While the process was going on, I felt a pulsation that I reported to the doctor. I still feel it seven months later. Other symptoms include low blood pressure, an increase in weight, and digestive changes. My primary care doctor thinks that my vagus nerve could have been damaged when the pacemaker was implanted. Is that possible?

  • 16. By the way, doctor. I seem to sweat a great deal from my hands and underarms, more than my friends do. Sometimes I can't write or shake hands because my palms are dripping with sweat. Is there anything I can do about this embarrassing problem?

  • 17. Ask the doctor. When I was diagnosed with atrial fibrillation four years ago, my doctor put me on a calcium-channel blocker. A year or so later, after I had angioplasty and got a stent, my doctor switched me to twice-a-day sotalol. Now I feel tired all the time and have gained weight, even though I feel like I am eating less. Can this be from the sotalol?

  • 19. Ask the doctor: My husband had a heart attack last winter. Although his doctor says his heart is now fine, he just has not bounced back the way I thought he would. He has trouble sleeping and no energy. I am concerned that he is going to continue on a downward spiral.

  • 20. Ask the doctor. I am 83 years old and have coronary artery disease that causes angina everyday with activities like climbing stairs. My doctor thinks I am going to need bypass surgery to get some freedom from my symptoms. Isn't it too risky at my age?
