I’m almost 26 weeks and I’ve dealt with tachycardia well before pregnancy but worse now pregnant . I had a heart monitor on and highest it went was 188! I don’t do strenuous exercise so the only thing I could have been doing is walking , doctor said it looked normal just fast which still leaves me with no answers ! Walking in the shopping centre today and my heart was going so so fast , definitely close to 180. Had to sit down for ages to try bring it down, can anyone reassure me my fast heart rate episodes won’t affect babies heart rate ? I did hear it can increase their heart rate , which is concerning as mine seems to be going faster than the babies!
