No.

If not would having
66 heart rate recovery in the first minute after maximal stress echo
exercise is stopped be considered normal,abnormal, average,above
average,excellent in an 47 year old 5' 11.5" to 6 feet tall and 186
pounds male?Thanks

It is not a concern.

Dr.Anrew B.Chung Would drop in heart rate of 66 beats or less in the
first minute after maximal (stress echo) exercise is stopped be better
for the health of the heart of the above person? If not would drop in
heart rate greater than 66 beats be better? By the way I know that a
drop in heart rate of 12 beats or less in the first minute after
exercise is stopped is abnormal,but what about the upper normal limits.
What would the upper normal limits be of drop in heart rate in the first
minute after maximal (stress echo) exercise is stopped?What's this test
used for and does it tell anything about longevity and mortality?Would
having >66 be better than having <12 beats?Thanks

Not necessarily. Depends on what the EKG looks like during the drop in
heart rate. Ischemia can cause the heart rate to drop. So can
increasing degrees if heart block.

No necessarily. See above.

It is but this would be a non-specific finding. Poor physical
conditioning can prolong heart rate recovery. Pain, bronchospasm,
dysrhythmias are other possible causes.

Not a concern.

Depends on the max heart rate.

It's part of the big picture that the physician/cardiologist has to
take in.

Depends on multiple factors including the entire clinical picture.
