Drivers who have had bypass surgery (CABG)
a. At least three months after the operation

c. Pass a 9 minute treadmill exercise test (Bruce protocol)
d. Echocardiogram to show that the LVEF (pumping power of the heart) is at 40%
Has anyone actually done one of those treadmill tests?
As far as I can make it it's a nine-minute test working up to 3.4 mph on a 14% gradient, which must be maintained for three minutes.
3.4 mph would be a slow jog, I think, but suspect the real killer (and I use the word advisedly

) would be the 14% gradient.
Thing is, if it's as I describe then I'm pretty sure many licensed drivers wouldn't manage that kind of pace, never mind those who've had heart bypass surgery, who are in all probability unlikely to be in good shape otherwise.
According to the DVLA's website, "the patient should be able to complete 3 stages of the standard Bruce protocol or equivalent safely", then the measurements are taken etc.
According to Wiki stage 3 of the Bruce Protocol is 3.4mph on a 14% gradient
https://en.wikipedia.org/wiki/Bruce_protocolI think it’s a walk well according to the expert.
This measures LVEF (Left Ventricular Ejection Fraction) - To drive this figure needs to be at least 40%.
For various reasons some drivers are unable to walk sucessfully on a treadmill.
In these cases there is an alternative - stress echocardiography. This test is not dependent on the ability to walk on a treadmill.
In my experience most but not all drivers who fail the treadmill test are succesful in passing stress echocardiography.
If you feel that you may not be able to do 9 minutes on the treadmill then it is often best to have a stress echocardiogram.
