Premature ventricular complex-induced chronic cough and cough syncope

Abstract

The present case study reports a case of chronic cough and cough syncope associated with frequent premature ventricular complexes (PVCs).Careful analysis of cough-related symptoms and ECG monitoring led to the suspicion of PVCinduced cough. A coincidence between PVCs and episodes of cough was also documented by a portable multichannel recorder. Moreover, Doppler echocardiography revealed a PVC-induced transient increase in the pulmonary artery blood flow.After exclusion of other possible aetiologies, complete relief of chronic cough and cough syncope was achieved by radiofrequency ablation of the arrhythmogenic focus located in the right ventricular outflow tract.Premature ventricular complexes should be considered as a cause of chronic cough and cough syncope and an interdisciplinary cooperation can lead to successful diagnosis and treatment of this condition.

Cough-Induced Syncope as an Unusual Manifestation of Pericardial Effusion

“…For example, atrioventricular conduction block due to hypersensitive broncho-pulmonary reflex, a neurally-mediated reflex contributing to an inappropriate chronotropic response or a premature ventricular complex, may cause cough-induced syncope. 1,[5][6][7][8] Cough-induced syncope in the patient described above was associated with hypotension. Bradycardia or arrhythmias were not documented during the episodes.…”

Asthma-like attacks terminated by slow pathway ablation

“…There are some supraventricular arrhythmia [10] and ventricular arrhythmia [11] cases reported in the literature presenting with the symptom of coughing which may be thought to be a respiratory tract disease, at first glance. The possible mechanisms of arrhythmia causing cough speculated by the authors in these patients are anatomical close relationship of phrenic nerve and atrium causing supraventricular arrhythmia and increased pulmonary artery blood flow causing ventricular arrhythmia.…”

High-Resolution Esophageal Manometry with ECG Monitoring for Management of Premature Ventricular Complexes-Associated Dysphagia

“…Besides the typical symptoms of PVC (palpitation, chest discomfort, dyspnea, dizziness, syncope), some uncommon symptoms should be evaluated. Recently, a PVC-induced cough reflex which with PVC-associated dysphagia may share similar interaction and reflex mechanisms, has been reported [6,7,13].…”
