I am 26 years old male .2 years ago i was undergone stent angioplasty.now for few days my heart is beating fast .i feel shocking for small reasons like somebody suddenly opens door,while driving if other vehicle just crossed me suddenly like these things my heart is beating fast.i feel anxious for silly reasons.
Hello, I would explain that anxiety may mimic this clinical situation.  Anyway, I would recommend checking thyroid hormone levels in order to exclude a possible thyroid gland dysfunction, blood electrolytes for possible imbalance and complete blood count for anemia.  If these metabolic disorders have been excluded, I would recommend performing an ambulatory 24-48 hours ECG monitoring in order to exclude possible cardiac arrhythmia. Hope I have answered your query. Let me know if I can assist you further.
