AB ESSENTIALS  OF  DIAGNOSISWide  variation  in  sinus  rate  is  common  in  young,  healthy  individuals  and  generally  not  pathologic.Symptomatic  bradycardia  may  require  permanent  pacemaker  implantation,  especially  in  the  elderly  or  patients  with  underlying  heart  disease.Sinus  tachycardia  is  usually  secondary  to  another  underlying  process  (ie,  fever,  pain,  anemia,  alcohol  withdrawal).Sick  sinus  syndrome  manifests  as  sinus  bradycardia,  pauses,  or  inadequate  heart  rate  response  to  physiologic  demands  (chronotropic  incompetence).
