32 y/o. last monday i had palpitations. felt like 3 irregular quick beats that werent as strong as the original beat. then followed with a normal beat. lasted 2 hours. is it afib? im a huge hypochondriac.

Hard to guess: That is the curse of having health anxiety. Normal bodily sensations and abnormal bodily sensations all are perceived as signs of illness... making it very difficult for either the patient or the doctor to tell when the patient is actually sick (other than suffering the sickness of health anxiety). The patient can teach himself which of his pains, his sniffles, his heartbeats, etc..., are normal.
