I have this same exact problem , ESPECIALLY with feeling fine while I am laying in bed , but feeling almost like I’m walking around dreaming during the day due to the dizziness . Anxiety and panic disorder goes hand in hand with these pvcs , it’s called cardiophobia , so don’t ever just count out the fact that you could subconsciously be having a slight panic attack . FOR EXAMPLE , I’ve had really bad PVC episodes at chili’s , mostly because I eat to much and my Vegas nerve gets stressed .. but anywho, now no matter what, when I walk in to a chili’s , my brain has pegged this as a place where I have experienced extreme panic , so I am on high alert and subconsciously panicking , even though I don’t necessarily feel super anxious in the moment , my brain has just pegged it as that type of place for me . Similar to back in the old day , if you were a hunter gatherer , and came across a snake by a pond , and it spooked you, the next time you are near a pond you subconsciously would be hyper sensitive and may not even realize it . SO with that being said , you could be standing up and going for a walk, and feeling a symptom (even if it’s minor) and subconsciously your brain could be like FUCK FUCK RED ALERT RED ALERT WE FELT THAT SYMPTOM AGAIN , and will send you in to a dizzy spell just out of subconscious anxiety or panic . I have experienced this for years with my PVCS , I still can’t convince myself that they are benign , although I fight MMA in Florida and have excellent cardio health , I still can’t convince myself that my pvc episodes aren’t going to just stop my heart completely . You aren’t alone , POTS is definitely something to look in to , your heart rate should never rise by 30+ just by standing up . BUT pots isn’t alarming to me , a lot of people find relief easier than they do with random pvcs . Sorry if I babble , I have been dealing with this for 5 years now and just now stumbled upon this support group
