<s>[INST] My heart has skipped beats everyday for the past 15 years. No other symptoms, but it is still scary when it happens. If I move a certain way it will do it. Caffeine triggers it also. I am just worried that one day it will happen and wont correct itself on its own. It stops me from being active and doing things I know are good for me like exercising. I was diagnosed a few years ago with a slight mitral valve prolapse but dont see how this will cause a skip in my heartbeat. [/INST] Hello, Most probably these are ventricular premature complexes. These are ectopic or extra beats. These are usually benign and not life-threatening. These are frequently associated with MVP, also caffeine, alcohol, thyroid problems may aggravate these.  So before going ahead we need to confirm it. Since these are not frequent ECG may be normal, so in that case you'll need 24 holder monitoring which can diagnose these.  You should also get thyroid test done.  Avoid smoking, alcohol and caffeinated products. You should also discuss with your local doctor regarding Metoprolol XR 25 mg once a day, which will suppress these beats. Hope this helps you and get back if you have any questions. </s>
