The conclusion at the hospital was that Mum has a normal heartbeat, then some erratic beats, then normal again. He thinks it can be sorted with meds. It was a lovely little hospital, very "Welsh" which helped Mum as she's far more comfortable through the medium of Welsh. I'm glad I was there, as she did forget some important details.
The journey home wasn't much fun as the wind increased even further, and though I shouldn't laugh, but I had to grab Mum and the trolley as they sailed off in Aldi car park. Again the weather was calmer in Tremadog, but I had a rough trot home. WOW that was some wind, I couldn't even open the car door when I got home! Thankfully, it's calmer this evening, so hopefully we can "do something" tomorrow!
