[|AI|]  Hello, It could be an arrhythmia: abnormal heart rhythm. They are usually benign and can be treated. But for finding it you need to undergo a 24-hour ECG Holder test. This is an examination, when a small device with ECG leads are attached to you. You carry it with you for a day, and it registers your ECG for a whole day, so your doctor can see what is happening with your heart when you have palpitations and complaints. Only after finding out what is the cause they can treat you. Hope I have answered your query. Let me know if I can assist you further.
