I’m almost 36 weeks pregnant and for the last couple weeks I’ve been having an increase in heart rate (140-160) and my legs get weak and i feel like i could pass out... usually when I’m standing or walking but sometimes also just sitting(blood pressure remains normal)so i call to notify my doctor and he sends me to a cardiologist... go to the cardiologist which makes it seem like it’s most likely just due to pregnancy but he wanted to do an echo to check for cardiomyopathy. Echo scheduled for Friday.. has anyone else experienced these symptoms?? If so what did they say it was. I’m a ER nurse so i do have a good grasp on this kind of stuff but still pretty concerned... 😔
