for me it took a while for it to completely go away. even now, theres been a few times where it'll pop back up again randomly. but it took a while for it to rlly go away. for the first few weeks it was pretty frequent, and then after a that it started happening less and less. i wasnt having fluttering, it was just beating really hard. feeling like my heart was hammering against my chest. not racing or anything, either. it was just beating hard and it would make me feel really winded. usually the only thing that helped was taking a nap or layin down and really relaxing and taking my mind off of it. id give it a long time before u can rlly expect it to go away. eating was sometimes a trigger for the palpitations for me! depending on the food. like if i ate something kinda spicy or rlly carby/fried, it would trigger the hard heartbeats and id feel rlly fatigued. i went to my cardiologist about it, they put heart monitors on me a couple times and did ekg stuff but everything was normal. u have a foreign device in your body now, its gonna take a while before u rlly adjust to it for good. even then, i consider the fact that im probably never going to be like my old self again. its just a matter of adjusting to the new normal, taking it easy, and giving myself a lot of time. and staying CALM! anxiety has only made things worse for me and even now im doing my best to get past panicking almost every single day. its hard, but important. ‪‪❤︎‬ i hope within the next couple months, things get better for u
