Armbro Obvious is a 6 year old Standardbred gelding.

Armbro was claimed by the current owners in January of 1999.  The gelding had a history of atrial fibrillation in 1997 that was successfully treated.  He raced well for the current owners (10 starts) until his last start 20 days prior to presentation.   The gelding was trained on the day of presentation and was very distressed post training with an irregular heart beat and a heart rate of 150 beats/minute.  Forty minutes after exercise the heart rate was 120-130 beat/minute and the rhythm remained irregular.
