Hello @sharongyl64,

You may notice that I moved your discussion and combined it with this one asI thought it would be beneficial for you to be introduced to @winom who has mentioned a similar issue.

To put it simply, diastolic dysfunction is when the heart muscle becomes stiff and blood can back up into the lungs causing shortness of breath (also known as heart failure with preserved ejection fraction).
Systolic dysfunction is when the heart muscle is weak and heart function is reduced (heart failure with reduced ejection fraction).
Sometimes, it is possible to have a combination of both these conditions.

I found a few published studies about systolic-diastolic cardiomyopathy which might interest you:

I'm also tagging @bigdaddye @braves04 @martishka @kenv267 as they've talked about atrial flutter and might have some thoughts to share. How are you feeling now, @sharongyl64?
