Short term memory GONE

On Feb. 6, 2017 at 5:00 am in Walmart while looking at ham steaks I went down, Unconscious . Haven't a clue how long I was out but wound up in a heart hospital in Richmond, Va.
After two days I went home with a monitor the size of a cell phone and started transmitting to Pa 24/7 and where they in turn reported to my cardiologist here in Richmond daily. Received a call from the doctors nurse asking if I realized my heart stopped for four seconds a couple times. Arrangements were made for a pacemaker. 24 hours after receiving the pacemaker I went home.
It didn't take but a few minutes to realize I lost my short term memory. If my life depended on it I could not tell anyone my phone number. I opened the freezer door on the refrigerator and left it wide open. It took four times to write one check correctly and that was the first day. I needed ketchup for cocktail sauce for shrimp. As I pulled into the store parking lot I hadn't a clue as to what I needed. It went downhill from there. There are many other problem I had because of short term memory loss. My primary care doctor told me I will not get the short term memory back do to the lack of blood to the brain. I put an alarm on the freezer door which goes off when opened. Hopefully I'll remember to write a note for what I need from the store. I see a neurologist on 4/13
