Possible Causes

Chronic Bronchitis

A 49-year-old woman complained of cough and a purulent sputum (about 40 ml/day). She kept budgerigars for a period of 30 years, she first noticed a productive cough 10 years previously. Her chest roentgenogram revealed a diffuse reticulonodular pattern. She was diagnosed as having a chronic type of budgerigar[…] [ncbi.nlm.nih.gov]

Sinus Tachycardia

Sinus tachycardia is a common condition, in which the sinus rhythm exceeds 100 beats per minute. This results from an increase in the number of impulses arising from the sinus node. The prognosis of the condition is not too good, particularly in patients with cardiovascular diseases. Many of the patients with sinus[…] [symptoma.com]
