Reviewing With the Staff

When assessing a patient with chest pain, it is important to consider sinister causes while also keeping in mind the prevalence of these conditions. In doing so, assessments are initially focused on common conditions, and then adapted to explore less common conditions as directed by the clinical assessment. This leads to thorough but efficient assessments of time-sensitive and potentially life-threatening conditions.
