Thanks for writing to us.
Our heart beats usually 60-80 beats/mt.Average heart beats is taken as 72/mt.If the heart beat is more than 90/mt it is called as Tachycardia
and if it is less than 50/mt ,it is called Bradycardia
The increase in the heart rate
could be either Physiological(normal conditions such as walking /running/drinking/eating etc) or Pathological (Fever due to any cause/Anemia/Hyper thyroidism/Arrhythmias/Anxiety Neurosis).The list can go on.
In your case as you have yourself pointed out ,it could be due to anxiety.However kindly undergo an ECG during tachycardia ..and Physical Examination by a physician to rule out Organic Causes.
As the increased heart beat itself can cause anxiety and worsen the situation ,kindly find out the root cause of increased heart beat.
In your case you have not mentioned your heart rate but you have mentioned about the feeling of pounding of your own heart that is called palpitation
In all probabality, you may be put on an Beta Blocker
or /and an anxiolytic medication which will control your heart rate as well as your anxiety.
Pls consult a General physician first and then only a Psychiatryst.
Wishing you a speedy recovery.,
