AB  - Cardiovascular  collapse  is  severe  hypotension  from  acute  cardiac  dysfunction  or  loss  of  peripheral  vasculature  resistance  resulting  in  cerebral  hypoperfusion  and  loss  of  consciousness  (See  Table  306-1).  This  condition  can  be  the  result  of  a  cardiac  arrhythmia,  severe  myocardial  or  valvular  dysfunction,  loss  of  vascular  tone,  and/or  acute  disruption  of  venous  return.  When  an  effective  circulation  is  restored  spontaneously,  patients  present  with  syncope  (see  Chap.  21).  In  the  absence  of  spontaneous  resolution,  then  cardiac  arrest  occurs,  ultimately  resulting  in  death  if  resuscitation  attempts  are  unsuccessful  or  not  initiated.  Underlying  etiologies  for  cardiovascular  collapse  include  benign  conditions,  such  as  neurocardiogenic  syncope,  but  also  life-threatening  conditions  including:  ventricular  tachyarrhythmias;  severe  bradycardia;  severely  depressed  myocardial  contractility,  as  with  massive  acute  myocardial  infarction  (MI)  or  pulmonary  embolus;  and  other  catastrophic  events  interfering  with  cardiac  function  such  as  myocardial  rupture  with  cardiac  tamponade  or  papillary  muscle  rupture  with  torrential  mitral  regurgitation.
