The cough reflex is an airway defensive process and it is also very common symptom that lead patients to seek medical attention. A bidirectional relationship between cough and heart dysfunctions exist. While the effect of robust switches of intrathoracic pressure during cough on haemodynamic and electrophysiological parameters are well known, mechanisms of so called “cardiogenic cough” are less understood. Cough induced by cardiac pathologies (mainly arrhythmias) is interesting and underestimated phenomenon. This condition is usually associated with the presence of abnormal heart rhythms and ceases with successful treatment of arrhythmia either by pharmacotherapy or by radiofrequency ablation of arrhythmogenic substrate. The two main hypotheses on heart-cough relationships (reflexogenic and haemodynamic) are discussed alongside with some uncommon cases of cardiogenic cough.
