Does the recipient of a heart transplant inherit the resting heart rate of the donor?

Only sort of.  After a transplant, the heart is generally not connected to the nerves that regulate rate.  But cardiac muscle is not like skeletal muscle, in that the nerves do not directly initiate contraction, they just speed it up or slow it down.  The heart itself has autorhythmicity.  Not connected to those nerves, the heart will beat at its intrinsic rate, which is usually around 100 bpm.
