Echo ef is 60 calculated, 55 visual estimate, and 63 on nuclear stress test. what's most accurate?
5 doctors weighed in across 2 answers
EF: All three of these numbers are reasonably close and normal. All methodologies have ranges of accuracy and error factors. In theory the nuclear method is the most accurate of these three but again technique can cause error.
