Had been doing much better, but now I'm having a devil of a time with heart palpitations. At least a few times a day, I get a skipped beat and a thud. It just ruins my whole day and sends me into a spiral. I had a full cardiac stress test and imaging done about 2 years ago, but am now concerned that it has been too long. How often do you get these? Do they come out of nowhere? When it happens when I'm excited or my heart is racing, it makes sense. But at least a few times a day, I get one when I'm just sitting there doing not much of anything. Does that happen to you? Do you ever feel like your heart is being "weak" or anything?
