i was taken to hospital wednesday in ambulance. thursday they did tilt table test which i tested positive. i passed out. i have not felt well for months, my dr had me wear a heart monitor for a month. to my knowledge i never had pvc. i have woke up a few times gasping for air. from my understanding this is from laying or sitting to standing up. i can be sitting or laying & not getting up & get dizzy & light headed. my mother has electrical problem with her heart which never showed up on ekg or blood work & she went to hospital thinking she had ate some bad food. all her blood work, ekg was normal & she flat lined. they life flighted her to a bigger hospital & they told her she was fine her blood work & ekg was normal & she did it again. she now has a pace maker. we discussed my symtoms not knowing hers & they were the same. my left arm has ached & i would sit up in recliner not laying down did not want to feel this way. just trying to see if this is what i truly have neurocadiogenic syncope since i feel bad lying down or just sitting? they told me to eat 15 grams of salt a day & drink lots of water. i drink lots of water since i donated my kidney to my husband in 2008.
