Pacemakers are added by doctors to regulate fast or slow heartbeats caused by improper SA node function. Pacemakers are implanted just under the skin as shown in the picture.

For a human, a missing chamber means that a person will need corrective surgery as an infant or may die. ]]> 2017-11-24 19:03:42 UTC https://padlet.com/llynn4/qsx1m6vwbzv/wish/209970384 https://padlet.com/llynn4/qsx1m6vwbzv/wish/209974783 How many chambers in the human heart?]]> 2017-11-24 19:47:47 UTC https://padlet.com/llynn4/qsx1m6vwbzv/wish/209974783 allysabertillo16 https://padlet.com/llynn4/qsx1m6vwbzv/wish/210250764 What can happen if there are disruption to our regular blood flow?
