An electrocardiogram (ECG) is helpful in establishing baseline findings and differentiating clinical symptoms (eg, chest pain, dyspnea). Changing lung hemodynamics often alter ECG wave patterns.

Bedside tests for peak expiratory flow provide good indicators of significant airflow obstruction. Lung cancer is more closely linked to chronic obstructive pulmonary disease with airflow compromise than to the disease without significant airway obstruction.
