Time Lords may have two hearts, but Klingons have only one, eight-chambered heart (cf. TNG "Ethics").  See also the proverbs referencing a single heart:

  tIqlIj Da'angnIS 
  You must show your heart. PK

  tIqwIj Sa'angnIS 
  I must show you my heart. TKW

  tIqDaq HoSna' tu'lu' 
  Real power is in the heart. TKW
  ["In this phrase, the heart stands for one's spirit or
    principles." TKW 23]

Although there is this interesting bit from the paq'batlh (I don't know what the context is here):

  ngIq tonSaw' lo' 'ej tIqDu' lel 
  In one single move, he removed the hearts (PB, paq'raD, canto 23)
