Even though cough is a rare symptom, it is necessary to explain potential mechanisms between cough and PVC or other arrhythmias. PVCs should be considered a probable cause of chronic cough in the clinical setting.

Introduction Chronic cough, which is defined as a cough lasting for more than 8 weeks, is the most common symptom that accompanies a diverse range of respiratory diseases, non-respiratory conditions, and rarer conditions 1 , 2. Case Presentation This year-old female presented with daily productive cough and expectoration for 4 years and experienced recurrence for more than half a year.
However, the findings indicate that PVCs are seldom the sole cause. Prior research has linked various arrhythmias with chronic cough, but data from prospective studies has been lacking, Dr. Sebastian M. Stec, from Grochowski Hospital, Warsaw, Poland, and colleagues note. The study involved patients without organic heart disease who were referred for the evaluation of symptomatic PVCs. PVC-associated coughs were defined as ones that occurred immediately after spontaneous or induced PVC.
Ten patients had a chronic cough, according to the report in the June issue of Chest. However, PVCs were implicated as the sole cause of the cough in just one patient.
In five patients, PVCs were thought to play a contributing role to the cough. Other causes seen in these patients included nonasthmatic eosinophilic bronchitis, gastroesophageal reflux disease, and chronic sinusitis.
