AB  - Fifty-six patients with "poor R wave progression" (PRWP) on the electrocardiogram 
      (ECG) were studied by Frank vectorcardiography in an attempt to define 
      discriminators for subgroups. Criteria were prospectively applied to a test group 
      with achievement of comparable sensitivity and specificity. Four subgroups were 
      identified in the patients with PRWP: Group I - anterior myocardial infarction 
      (AMI) (20/56, 35%); Group II - left ventricular hypertrophy (LVH) (8/56, 14%); 
      Group III - right ventricular hypertrophy (RVH) (7/56, 13%); AND Group IV - 
      leftward axis (LA) (21/56, 38%). The best discriminator for vectorcardiogram 
      (VCG) AMI was RV3 less than or equal to 1.5mm or R1 less than or equal to 4.0mm 
      (18/20, 90% sensitivity; 26/36, 72% specificity). RVH and LVH were identified by 
      R1 less than or equal to 4.0mm and S1 greater than or equal to 1.0mm and standard 
      LVH voltage criteria respectively. Group IV patients (PRWP without VCG criteria 
      for AMI, LVH or RVH) were identified by exclusion. "Reversed R wave progression" 
      (RRWP) was more specific for AMI than was simple PRWP. The same discriminators, 
      however, were applicable. It is clinically useful to note that 72% (26/36) of 
      patients with either PRWP or RRWP who did not exhibit VCG AMI could be identified 
      by 12 lead ECG with only 2/28 (7%) VCG false negative AMI.
