Thank you Kora.

There might be stress also involved. I had to go to the hospital again on Thursday 7/2 as my heart started beating quite fast.
It was about 140 (more or less) when I was just sitting down and would not go down.

Enzymes were 2, which is the max allowed. Much better than my over 2600 four weeks ago.

No new Takotsubo but I was advised to start beta-blockers. I find this odd as my heartbeat was high when I had Takotsube a month ago and on Thursday again. Between my heart rate has been normal for 4 weeks. But they are only treating symptoms, not the cause.

Yesterday when my mother was giving me advice about how to live my life, my heartbeat was over 100 even though I was resting. When she stopped, it went quickly to 70. After the phone call to the resting beat.
The same thing when I was speaking to a friend about a task we do together; my heart rate went over 100 and he also noticed how full of energy I was when talking about it and advised to calm down.

I feel there is more than the shock that caused the Takotsubo. There seem to be also stress involved.
