I don't what the normal time span is but I've been having one yearly

I have one every 6 months

Since being diagnosed with W ATTR CM In Jan 2024 I have had 2 and I an having 1 in May at my checkup with Dr. Dibble. I see the other DR Abisse a month before Dibble, he might do one then at Balltown Rd. Schenectady, nby. I am stage 2 and am now in my 2ND year. Who knows?..

I am having one in June I think it is about every 6 months for me as I have other issues with my heart.

As needed as per my heart pattern.
