[|Human|] I have been having moments lately where my heart feels like its trying to jump out of my chest all of a sudden that come and go. Today I noticed that after wards I couldnt laugh because it would happen again. When I was younger I had a heart murmur. Is this it coming back?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, worsening office heart murmur can cause similar kind of palpitations. Actually heart murmur can cause arrhythmia (rhythm disturbances in heart). Some tachyarrhythmia like supra ventricular tachycardia (SVT), atrial fibrillation, atrial flutter etc. can cause pounding of heart. So get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). On the basis of these reports, you will need anti arrhythmia Chat Doctor.  Don't worry, you will be alright with appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
