My tachycardia was gone in the morning so didn't ring doctor. I'm wearing a two week holter recorder so it should be traced and I can ask about it when I see him. I pressed the green rectangle to record that I had felt it. The holter has to be returned to the hospital on Thursday. I was very very tired on Monday but much better today and have been clearing some debris in the garden. Keep well all of you and thanks for listening.
