Where in the heart is the 1st heart beat?
I assume you mean the primary contraction of muscles (systole) in a cardiac cycle, in which case, the answer would be in the atriums of the heart - the thin-walled spaces at the top of the heart. If you are refering to the actual 'beating' noise of the heart, this is actually made by the valves separating the atruims and the ventricles snapping shut. These are located just below the atriums, about 1/3 of the way down the heart.
