###Human: I have palpitations and premature beats since childhood. Should I be worried? ###Assistant: Hello. These premature complexes are probably originating from the ventricles. These are usually benign and not life-threatening. Considering your age, the primary concern is a coronary artery disease, which is also less likely as you have been observing these symptoms since childhood and also because you do not have any of the other key symptoms. Lack of sleep, stress, alcohol, smoking, and caffeinated beverages are well known triggering factors for sympathetic overactivity. I suggest the following: So overall, this is not a worrisome matter and getting investigations done is a matter of choice. Hope this helps you and get back if you have any questions.
