Curious about heart rates

Not for any scary reasons, but was wondering what people have found has happened to their heart rates with either anxiety or citalopram.

I am a confessed smoker (I know I know bad bad me) and also larger than the average bear...ahem. I have begun to notice my heart from time to time lately since starting the tablets, but since it has never gone above 94 (highish I know, but within the 80-100 safe range) I got curious about if it had increased since starting the tablets.

Just being nosy I guess lol
