Re: Meditronic Combination Pacemaker/Defibrillator

Posted By Beverly on June 26, 1999 at 12:09:09
I am sending this letter for my father . . .
My name is Russell Beachboard and I am going to be 80 years old this August.  I have had two major heart attacks and a quadruple bypass.  In Dec. 1995 I started to have fibrillations around 150 bpm.  Since this time I have had two combination pacemaker/defibrillators fail and am on my third.  Initially my heart stabilized between 70-86bpm but then jumped to 100 bpm.  I had electroversion; however, for the last 60 days my heart rate has been 90-95 bpm.  I am experiencing extreme tiredness and loss of stamina.  These are my questions.
1.  My pacemaker is a Medtronic combimation pacemaker/defibrillator.  My clinician has told me that the pacemaker portion establishes only the low rat at 70bpm but does not control the rate at anyother point.  I thought a pacemaker worked as a heart regulator, establishing a low to upper heart beat range and then controlling the heart at a level within these parameters?  Is this correct?
2.  What is the exact function of a combined pacemaker/defibrillator?
3.  What exactly is a dual pacemaker?  I understand that I have a problem  with the synchronization of my atria and ventricle.  Would this help?
    *Thank you for your great service*

I am sorry to hear of all your problems.  It is sad that we as pacemaker patients do not get any info about our devices.  I worked at the same hospital I had mine done and I had to beg for info.  I even had one of the cardiologists that I worked with, tell me that they did not want to give their patients too much info because it would make their jobs harder!  He did not know I had one! I have a Medtronic's dual chamber pacemaker.  I have had sinus arrest and slow and fast heart rates, called sick sinus syndrome. I know that Medtronic's makes the combination pacer/defibrillator.  They have a web site that may help you.  (www.medtronic.com). Also you may want to try this site too. (www.naspe.org) this is a site of EP doctors and they also have a patient page.  North American Society of Pacing and Electrophysiology (NASPE)
A pacemaker/defribrillator is not something I know about. I have the dual chamber because I need to have the synchrony between the atrium and the ventricle because I have trouble with just atrial pacing.  But if you check some of these sites they have much of the info you are asking about.
Take care.
