What is the difference between a palpate and a palpitation?

Palpate means to . Feel whereas palpitations is a perceived change in heart rhythm.
Totally different. To palpate means to touch and feel. In examining your abdomen the doctor palpates. A palpitation is a feeling you have in your chest that the heart is skipping or beating hard and fast.
Any dictionary. Can answer this: palpate = feel with your hands, palpitate = sensed skipped or extra beats in the heart. See my book "maximum healing" & my www.Thepmc.Org website.
