Do ECG signs of chronic cor pulmonale and PAO2-PaO2 >48 mm Hg during oxygen therapy predict short-term prognosis in COPD patients?
ECG signs of chronic cor pulmonale combined with specific blood gas parameters during oxygen therapy can identify COPD patients with poor short-term prognosis.
Some ECG signs of CCP and PAO2-PaO2 >48 mm Hg during oxygen therapy qualified as a simple and inexpensive tool for targeting subsets of COPD patients with severe or very severe short-term prognosis.
Incalzi et al. (Tue,) studied this question.
