@maribrat Ive been reading your response about dizziness.Have you had your ears checked? I had dizziness or vertigo for awhile then saw my EENT who sent me to a ventricular Dr specialist.He performed alot of different test found out the crystals in my ears where of balance ,hence dizziness.After he had me do ear exercises for a month 2x a day it finally cleared up .There are so many reasons for vertigo besides heart problems.I would suggest seeing a ear Dr .also
