Heart Sounds01:15

Heart Sounds

3.9K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Cardiovascular System Abnormal Findings II: Auscultation

683
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Aortic Regurgitation II: Clinical Features and Diagnostic Tests01:22

Aortic Regurgitation II: Clinical Features and Diagnostic Tests

635
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...

Mitral Regurgitation II: Clinical Features and Diagnostic Tests

582
Mitral regurgitation (MR) is a valvular heart disorder in which the mitral valve fails to close tightly, allowing blood to leak backward into the heart. Understanding the clinical manifestations, assessment, diagnostic findings, and medical management of MR is crucial to effectively managing affected patients.Clinical Manifestations of Mitral RegurgitationMitral regurgitation can be acute or chronic, each presenting differently and requiring different approaches:1. Acute Mitral...

Mitral Regurgitation I: Introduction

673
Mitral regurgitation is characterized by the backward circulation of blood from the left ventricle to the left atrium during systole, a phase of the cardiac cycle when the heart contracts and pumps blood out of the chambers. This abnormal flow occurs primarily due to the dysfunction of the mitral valve or its supporting structures, which include the mitral leaflets, chordae tendineae, annulus, and papillary muscles.Etiology and Mechanisms:Primary Mitral Regurgitation: This type arises from...

Anatomy of the Heart01:27

Anatomy of the Heart

121.1K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Summary

Accidental heart murmurs are common in children and have distinct characteristics, requiring minimal follow-up. Auscultation is key to differentiating these innocent murmurs from pathological ones.

Area of Science:

  • Pediatric Cardiology
  • Cardiac Auscultation

Background:

  • Accidental (innocent) murmurs occur in healthy hearts and possess defined clinical traits.
  • These murmurs are asymptomatic and necessitate minimal medical follow-up.

Purpose of the Study:

  • Highlight the importance of cardiac auscultation in distinguishing heart murmurs.
  • Detail the clinical characteristics of accidental heart murmurs.

Main Methods:

  • This article is a literature review.
  • Focuses on accidental heart murmurs within pediatric cardiology.

Main Results:

  • Common accidental murmurs include Stills murmur, pulmonary ejection murmur, venous hum, and carotid bruit.
  • These murmurs are frequently detected in children and adolescents.

Conclusions:

  • Accidental heart murmurs are found in over 50% of children, peaking between 3-6 and 8-12 years.
  • They are a frequent cause of unnecessary parental anxiety and cardiac referrals.
