<s>[INST] My mother is 95 .. has had a pace maker for 6-8 years .. her quality of life has greatly deteriorated so we are beginning to think the quantity instead of quailty is what shes finding .. she would not be here wwithout the pace maker .. what are her choices here? [/INST] Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. The pacemaker live duration depends on some factors like the pacemaker TIPE, if the patient has been pacemaker dependent or not meaning if he is all time in paced rhythm or not.These is factors that decide the lives of the pacemaker battery. Normaly the battery live might go up to 10 years but every thing depends on the previous factors. If the patient is all time in paced rhythm than the battery ends sooner and the patient situation get worse. So, in this situation, after this year's you should reevaluate the situation. If I was the treating doctor I will recommend a pacemaker battery control, a cardiac echo and a full blood analyze. After all this we can decide the best choice for your mother. Maybe she needs just a battery replacement. Hope I was helpful. Best regards, Chat Doctor.  </s>
