Ekg shows inverted t waves. normal sinus rythmn. palpitations feel like skipped beat followed by two hard slow thumps then back to normal. what is it?

PVC.: Sounds like you have a premature ventricular contractions or premature atrial contractions although i think these less likely. I would not be worried about inverted t waves in the absence of any other cardiac symptoms. To be absolutely sure these are what i think they are it would be reasonable to obtain a holter or event monitor and capture a few of these.

Not necessarily : Ecg is notoriously inaccurate, especially in the detection of ischemic heart disease. You should find a physician who offers multifunction cardiogram in his office. It is the most accurate in the detection of ischemia in women! please go find one, and it may save your life! http://en.M.Wikipedia.Org/wiki/multifunction_cardiogram.
