Only anecodotal, but thought I’d pass it on. Two or three weeks ago while visiting in Canada, I suffered a TIA. Short, not serious and subsequent tests showed no worrisome conditions or abnormalities (I ought to note the event happened during a raucus family wedding and there were certain types of misbehavior involved). My wife took control of the auto and we zipped to the hospital on Vancouver Island where I was taken in and tested with an administrative delay of five minutes.
By way of contrast, last evening I drove my wife to the hospital as she was experiencing some symptoms which might have been heart-related (they weren’t, as it turned out…everything quite fine heart-wise). We sat in the emergency waiting room for four hours before a doctor saw her.
