Hello I suffer from the terminal heart condition , Dilated Cardiomyopathy and as such I have got a pacemaker and also a WICS ultrasonic powered CRT implanted.
Two days ago I had the pacemaker battery replaced, up to the point of change you get no indication that the battery is low , so you carry on with your life,
Enter the hospital theatre and under local anaesthetic you have the pacemaker changed and when finished you feel sore around the wound site but other than that you carry on with your life.

Hiya,
Best thing is to ask your Doctor, I’ve got a defibrillator my battery runs out in 2yrs time, big hug 🤗

I have had Afib / bradycardia for many years, and am on my 3rd pacemaker. My 1st one was replaced after 8 years, and still had battery life left, and so I felt no impact before it was changed. For a number of reasons I did not have my my 2nd pacemaker regularly checked, and after 9 years the battery ran very low. For a number of months I was not feeling well. Out of breath, dizzy spells, etc. Turns out the pacemaker had gone into “battery saving mode” and was therefore not operating optimally. Bottom line is have your pacemaker checked annually, (not just ECG with your cardiologist!), and have it replaced before the battery runs out! Since it was replaced, back to living “normally”!

I go once a year to have my pace maker checked-This year will be 11 years that I have had one-the person who gave me the exam said mine would be changed in March of 2023-they usually last about 10 years-

I have an AICD. I became concerned when I felt a buzzing or vibration in my chest. I had been told my battery was getting low but no one told me there was a warning given by the device a few months before the batteries would lose their charge, leaving plenty of time for them to be replaced. The vibration did not hurt at all, but was frightening since I had not been warned in advance.
