Dear Welcome to HCM We understand your concerns I went through your details. You are experiencing missing heart beats. You consulted doctors in the past and all the tests came normal. I can understand. If your doctors say that you are clear for any heart related problem, you should believe it and live normally without having anxiety about heart health. I strongly suspect that you have the health anxiety disorder (hypochondriasis). When a person is health anxious, it is common for that person to feel the heart beat skipping. That is due to the obsession. I suggest you to consult a heart specialist just for confirmation. I am sure you will be clear. Request the doctor to consult you and help you with the tests. Then you should promise yourself, that this will be last. From now on, you will believe that doctor completely and live life without worries.
