Summary
Frequent premature ventricular complexes (PVCs) can cause chronic cough and cough syncope. Radiofrequency ablation of the arrhythmogenic focus successfully treated these symptoms, highlighting the importance of considering PVCs in diagnosis.
Area of Science:
- Cardiology
- Pulmonology
- Electrophysiology
Background:
- Chronic cough and cough syncope are common symptoms with diverse etiologies.
- Premature ventricular complexes (PVCs) are typically associated with cardiac arrhythmias, not typically with cough-related symptoms.
Observation:
- A case study identified a link between frequent premature ventricular complexes (PVCs) and chronic cough with cough syncope.
- ECG monitoring and a portable multichannel recorder confirmed the coincidence between PVC episodes and coughing fits.
- Doppler echocardiography showed a transient increase in pulmonary artery blood flow induced by PVCs.
Findings:
- The study identified PVC-induced cough as the cause of the patient's chronic cough and cough syncope.
- Radiofrequency ablation successfully eliminated the arrhythmogenic focus in the right ventricular outflow tract.
- Complete resolution of chronic cough and cough syncope was achieved post-ablation.
Implications:
- Premature ventricular complexes should be considered a potential cause of chronic cough and cough syncope.
- Interdisciplinary collaboration between cardiology and pulmonology is crucial for diagnosing and managing this condition.
- Radiofrequency ablation offers an effective treatment for PVC-induced cough and syncope.

01:25Chronic Obstructive Pulmonary Disease-III: Symptoms and Complications.
Understanding the variety of primary symptoms and systemic complications that characterize chronic obstructive pulmonary disease (COPD) is crucial for healthcare professionals.
Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

01:19Chronic Obstructive Pulmonary Disease IV: Clinical Manifestations
Chronic Obstructive Pulmonary Disease, or COPD, is a long-term condition marked by persistent and only partially reversible airflow limitation. It involves two overlapping conditions—chronic bronchitis and emphysema—which often co-appear but differ in dominant symptoms and underlying mechanisms.Chronic Bronchitis FeaturesChronic bronchitis presents with a persistent productive cough and thick, sometimes purulent mucus due to airway inflammation, enlarged mucus glands, and goblet cell...
01:20Chronic Obstructive Pulmonary Disease-II: Pathophysiology
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:

01:20COPD: Pathogenesis and Clinical Features
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:28Dysrhythmias II: Classification of Tachyarrhythmias
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...
