@stoyangv Welcome to Mayo Clinic Connect. We aren't medical professionals here and we can provide you with support and help you to advocate for yourself. May I ask what your resting heart rate was before you started on escitalopram? When do you measure your resting rate and how do you measure it? I use my Apple Watch and my primary care physician told me that while the Apple Watch isn't a reliable medical device it does give a hint of what my heart rate is and she finds this information useful in our appointments.

Did your primary care provider prescribe the escitalopram? I recommend that you contact your prescribing physician and ask about this. Your question requires a medical opinion. Do you have a patient portal to contact your physician? Or will you call your physician today?
