[|Human|] well sometimes ill be sitting, standing or walking and out of nowwhere it feels like my heart juss suddenly hesistates to beat...so it will hesistate then beat what could this be?
[|AI|]  Hello, Your symptoms could be related to anxiety. Nevertheless, I would recommend performing some tests in order to exclude any possible cardiac arrhythmia or metabolic disorders: - a resting ECG and cardiac ultrasound-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance-complete blood count for anemia.  A 24-48 ECG Holder monitoring would help exclude possible cardiac arrhythmia.  If these tests result normal, you should consider anxiety as the main cause of your complaints.  Hope I have answered your query. Let me know if I can assist you further.
