Hello and welcome to Healthcare Magic. Thanks for your query.
Having missed or irregular heartbeats can be due to various medical conditions and can sometimes be indicative of a serious cardiac problem also. So, it is essential that you need a proper evaluation first, before trying any remedial measures.
I would advise you to see a doctor for a detailed physical examination and further investigations, like an ECG, so that a correct diagnosis can be made. Further treatment will depend on the diagnosis. If all medical causes are ruled out, then it is possible that this could be stress
related - in which case, you can try breathing exercises and other relaxation techniques
Wish you all the best.
Dr. Jonas Sundarakumar
