+# This is an extremely difficult record.  The predominant rhythm is normal
+# sinus with first degree AV block and left bundle branch block.  There are
+# periods when the conduction block changes to a right bundle branch block
+# pattern.  The PVCs are multiform.  Idioventricular rhythm appears following
+# the longest episode of ventricular flutter.  The record ends during the
+# episode of SVTA.
