AB Learning  ObjectivesBy  the  end  of  the  chapter  the  student  will  be  able  to:Draw  a  typical  action  potential  in  a  ventricular  muscle  and  a  pacemaker  cell.Describe  the  ionic  basis  of  the  phases  of  the  action  potential.Explain  the  significance  of  the  long  duration  of  the  cardiac  action  potential  and  the  resultant  long  refractory  period.Describe  the  normal  sequence  of  cardiac  activation  and  conduction  and  predict  the  consequence  of  its  abnormalities.Discuss  the  significance  of  “overdrive  suppression”  in  a  natural  pacemaker  and  the  abnormalities  leading  to  an  “ectopic  pacemaker.”Explain  the  effects  of  the  sympathetic  and  parasympathetic  nervous  system  on  the  heart  rate,  cardiac  conduction,  and  contractility.Describe  the  main  components  of  a  normal  ECG  recording,  their  significance,  and  abnormalities.
