Abstract
Exercise t e s t ia one of the most widely used
non invasive diagnostic t e s t s i n cardiovascular
medicine. The t e s t is mainly used for evaluating
p a t i e n t s with chest p a i n i n whom coronary a r t e r y
disease is mspected. Sxercise t e s t has the advantages
of being simple, inexpensive and safe. However
the high incidence of f a l s e positive and f a l s e negat
i v e r e s u l t s has been repeatedly c r i t i c i s e d .
The c l a s s i c a l method of exercise t e s t interpret
a t i o n depends upon the dection and evaluation of
exercise induced ST segment depression. Recently
other c r i t e r i a for t e s t i n t e r p r e t a t i o n were studied
and recommended by many authors. These c r i t e r i a
includes R wave amplitude changes, &, RST index,
changes i n the QT i n t e r v a l and G.X/QT r a t i o , exercise
induced arrhythmia, U wave inversion and, changes i n
heat r a t e and blood pressure.
The a i m of this ;vork is to study the diagnostic
value of each of these c r i t e r i a and to compare them
~Icith the c l a s s i c a l ST segmest depression i n agroup

Also the value of the exercise t e s t i n predicting the
