Pleuritic chest pain, chest pain reproduced by palpation, sharp or stabbing chest pain, positional chest pain.

A

3 x less likely to have ACS

31
Q

What is SPPIN and SNNOUT?

A

SPPIN-> highly specific test when it is positive will help you rule in a disease
SNNOUT->Highly sensitive test when it is negative will help you rule out a disease
Likely hood ratio greater than one rules in a disease while a likely hood ratio less than one rules out a disease.

32

normal

34
Q

  • Pulmonary Rales
  • JVD
  • Hepatojugular reflex
  • Diminished pulses
