Medical Criteria – R

RIGHT BUNDLE BRANCH BLOCK (RBBB):

• Complete RBBB
  • QRS duration >120 msec
  • Positive QRS in lead V1 (rSR’ or occasionally broad R wave)
  • Broad S waves in leads I, V5-6 (>40 msec)
  • Usually, secondary T wave inversion in leads V1-2
  • Frontal axis determination using only the first 60 msec
  • RBBB: V1 is positive (rSR’), V6 has broad S wave
• Right Ventricular Hypertrophy (RVH):
  • Right axis deviation
  • R/S ratio >1 or qR in lead V1
  • RV strain pattern: ST segment depression and T wave inversion in leads V1-2
• Right Atrial Enlargement (RAE):
  • P wave >2.5 mm in height in leads II, III, or aVF (“P pulmonale”)

RANSON’S CRITERIA:

• At admission

1. • Age >55 yr
   • WBC >16 x 10⁹/L
   • Glucose >11 mmol/L
   • LDH ≥350 IU/L
   • AST >250 IU/L

• During initial 48 h

1. • Hct drop >10%
   • BUN rise >1.8 mmol/L
   • Arterial PO2 <60 mmHg
   • Base deficit >4 mmol/L
   • Calcium <2 mmol/L
   • Fluid sequestration >6 L

• Interpretation
  • ≥2 = difficult course
  • ≥3 = high mortality (≥15%

ROME IV DIAGNOSTIC CRITERIA:

• Straining, hard stools, sensation of incomplete evacuation, use of digital manoeuvres, and/or sensation of anorectal obstruction/blockage with 25% of bowel movements and <3 bowel movements per wk. The criteria must be fulfilled for the last 3 months with symptom onset ≥ 6 months prior to diagnosis.

ROCHESTER CRITERIA

• Developed to Identify Infants ≤60 d of Age with Fever at Low Risk of Serious Bacterial Infection

RHEUMATIC FEVER:

• Clinical diagnosis based on Jones Criteria (revised)
  • Requires 2 major OR 1 major and 2 minors PLUS evidence of preceding strep infection (history of scarlet fever, GAS pharyngitis culture, positive rapid Ag detection test, ASOTs)

PULMONARY EMBOLISM RULE OUT CRITERIA (PERC):

• Prospective Multicentre Evaluation of the Pulmonary Embolism Rule Out Criteria

• • J Thromb Hemost 2008; 6:772

• • • Age less than 50 yrs.
    • Heart rate less than 100 bpm
    • Oxyhaemoglobin saturation ≥95 percent
    • No haemoptysis
    • No estrogen use
    • No prior DVT or PE
    • No unilateral leg swelling
    • No surgery or trauma requiring hospitalization within the past 4 wks.
• Acute PE can probably be excluded without further diagnostic testing if the patient meets all PERC criteria AND there is a low clinical suspicion for PE, according to either the Wells’ criteria or a low gestalt probability determined by the clinician prior to diagnostic testing for PE.

RHEUMATOID ARTHRITIS:

• 2010 ACR/EULAR Classification Criteria for Rheumatoid Arthritis

(Score-based algorithm: add score of categories A-D; a score of 6/10 for definite Rheumatoid Arthritis)

• Arthritis Rheum 2010; 62:2569-2581
