My husband had his pacemaker/defibulator replaced last tuesday, he keeps falling asleep/and was dizzy a few times, he is type 2 diabetic( no insulin), and takes warfarin. bp this am 79/54 now 96/67/blood is 1.6 should be 2-3/ sugar 110 after protein?

Check with provider: His blood pressure sounds a little low. Given the pacemaker has recently been replaced it would be less likely a pacemaker problem. However, is his pulse OK? He is diabetic and how is his kidney function? I am sure he is on BP meds and if kidney function worsening he could be getting low BP from meds. I would let your cardiologist or PCP know about the low BP
