[|Human|] I am a 33 year old female.  I was diagnosed with a slight heart murmur when I was 6 years old.  I often get palpitations where it feels like my heart is going to jump out of chest.  Tonight I have a resting heart rate of 104.  I am very aware of my heart beating (if that makes sense).  Is this ok?
[|AI|]  Hello! Thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms may be related to a cardiac arrhythmia. Your past medical history for a heart murmur is concerning about a possible structural cardiac cause of elevated heart rate. I recommend consulting with the cardiologist for a careful physical examination, a resting ECG and cardiac ultrasound. An ambulatory 24-48 hours ECG monitoring is necessary to examine your heart rhythm trends during the day. Some blood lab tests (complete blood count, blood electrolytes, thyroid hormone levels) are needed to exclude other secondary causes of elevated heart rate. Hope to have been helpful! Best regards!
