Detect risk with Automate Exercise ECG
The evidence shows that resting ECG fails on both essential criteria
for a screening test, high specificity and high sensitivity, in that
order. Low specificity inevitably generates unnecessary worry and expense.
It is not unreasonable to assume that an exercise ECG satisfies both
criteria so far as the target abnormality, induced exercise-induced
cardiac arrhythmia, is concerned. An an initially blinded automated system
similar to that used in defibrillators provides the solution. The system
would allow the test to proceed unless the resting trace showed a clearly
dangerous resting abnormality and stop the test if one developed. Although
no trace would show the memory would retain it for necessary refence.
Required training would be little more than that necessary to understand
and operate the accompanying defibrillator. If this practice became
prevalent the cost would fall rapidly particularly if the accompanying
treadmill was dual purpose being available for general use at other times.
