- A 55 year-old man with chest pain of unknown origin was referred for an exercise stress echo, but the results were uninterpretable for abnormal movement of the interventricular septum.
- The patient agreed to participate in a study protocol on CPET in LBBB. Oxygen uptake and O2pulse kinetics during exercise reflect cardiac output and stroke volume, respectively, which are flattened when myocardial ischemia develops.
- As a result, CPET may be used to detect/exclude inducible myocardial ischemia when ECG is uninterpretable.
