Summary
Allergic rhinitis patients show altered autonomic nervous system function, specifically reduced sympathetic activity in the sitting position. This suggests autonomic dysfunction may contribute to allergic rhinitis.
Area of Science:
- Cardiology
- Immunology
- Autonomic Neuroscience
Background:
- Limited research explores the autonomic nervous system's role in allergic rhinitis.
- This study investigates autonomic function in allergic rhinitis using heart rate variability (HRV).
Purpose of the Study:
- To evaluate autonomic nervous system activity in patients with allergic rhinitis.
- To compare HRV parameters between allergic rhinitis patients and healthy controls.
Main Methods:
- Eleven allergic rhinitis patients and 13 healthy controls (aged 19-40) were enrolled.
- Diagnosis confirmed by clinical history, symptoms, and Phadiatop test.
- Electrocardiographic recordings were taken in sitting and supine positions for HRV analysis.
Main Results:
- No significant differences in HRV parameters were observed between groups in the supine position.
- In the sitting position, allergic rhinitis patients exhibited increased mean RR intervals and decreased LF% and LF/HF ratio.
- Unlike controls, allergic rhinitis patients showed no significant changes in HRV with posture changes.
Conclusions:
- Allergic rhinitis patients may experience impaired sympathetic modulation when sitting upright.
- Autonomic dysfunction is implicated in the underlying mechanisms of allergic rhinitis.

01:22Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
01:28Asthma 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...
01:30Factors Influencing Heart Rate
The heart rate, or pulse rate, is a vital indicator of cardiovascular health. It reflects the number of times the heart beats per minute. Various physiological and environmental factors influence heart rate, increasing or decreasing cardiac output. Understanding these factors is crucial for assessing heart function and identifying potential health issues.
Let us explore the significant factors affecting heart rate, including age, body temperature, posture, acute pain, chemical influences,...

01:31Regulation of Heart Rates
The regulation of heart rate is a complex process controlled by the autonomic nervous system (ANS), hormonal influences, and intrinsic cardiac mechanisms. The ANS has two main components: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
