Insights

P-wave dispersion, a measure of sinus impulse propagation, was studied in children with stable asthma. Results showed a correlation between P-wave dispersion and anthropometric factors like age, weight, and height in these children.

Area of Science:

  • Pediatric Cardiology
  • Respiratory Medicine
  • Electrophysiology

Background:

  • P-wave dispersion reflects sinus impulse propagation heterogeneity.
  • Asthma can affect cardiac electrical activity.
  • Understanding these effects in children is crucial for comprehensive care.

Purpose of the Study:

  • To investigate P-wave dispersion in children with stable asthma.
  • To compare P-wave dispersion between asthmatic children and healthy controls.
  • To identify potential correlations between P-wave dispersion and clinical parameters.

Main Methods:

  • Cross-sectional study involving 20 children with stable asthma and 20 healthy controls.
  • P-wave duration measured via 12-lead surface electrocardiography.
  • P-wave dispersion calculated as the difference between maximum and minimum P-wave durations.

Main Results:

  • P-wave maximum duration was slightly increased in asthmatic children (0.092 ± 0.017 ms) versus controls (0.083 ± 0.011 ms), though not statistically significant (p=0.07).
  • Significant correlations were found between P-wave dispersion and age (r=0.40, p=0.01), weight (r=0.41, p=0.008), and height (r=0.41, p=0.008).

Conclusions:

  • P-wave maximum duration shows a slight increase in children with stable asthma.
  • P-wave dispersion is significantly correlated with age, weight, and height in this pediatric asthma cohort.

Asthma III: Clinical Manifestations01:13

Asthma III: Clinical Manifestations

Asthma presents with a characteristic pattern of episodic respiratory symptoms that reflect underlying airway inflammation, bronchoconstriction, and mucus hypersecretion. Although severity varies among individuals, certain clinical manifestations are considered hallmarks of the disorder and often guide diagnosis and assessment.Respiratory SymptomsA persistent cough is one of the most common early features of asthma. It is frequently dry and tends to worsen at night or in the early morning,...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Asthma-II: Pathophysiology and Classification01:26

Asthma-II: Pathophysiology and Classification

Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma-III: Symptoms and Complications01:24

Asthma-III: Symptoms and Complications

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications:

Antiasthma Drugs: β2-Adrenoceptor Agonists01:25

Antiasthma Drugs: β2-Adrenoceptor Agonists

Bronchodilators are critical in managing asthma, a chronic respiratory condition characterized by airway constriction due to inflammation and hyper-reactivity. Specifically, bronchodilators ease this constriction by relaxing the bronchial muscles, facilitating easier breathing.
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...
