Dysrhythmias III: Characteristics of Dysrhythmias01:29

Dysrhythmias III: Characteristics of Dysrhythmias

578
Dysrhythmias, also known as arrhythmias, are irregular heart rhythms that result from abnormal electrical activity in the heart, affecting its ability to circulate blood efficiently. Tachyarrhythmias, a subset of dysrhythmias, are characterized by abnormally fast heart rates exceeding 100 beats per minute. Here are some types of tachyarrhythmias with their distinct ECG features:Sinus Tachycardia:Sinus tachycardia presents a regular heart rhythm with an increased rate of 101-180 beats per...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

706
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Mitral Valve Prolapse I: Introduction01:27

Mitral Valve Prolapse I: Introduction

749
IntroductionThe mitral valve, one of the heart's four valves, regulates blood flow. These valves have flaps that open and close to direct blood properly through the heart and body. During each heartbeat, the flaps open for blood to pass through and seal shut to prevent backflow. Specifically, the mitral valve opens to allow blood flow from the heart's upper left chamber to the lower left chamber. It then closes securely as the lower left chamber contracts to pump blood to the body, preventing...

Development of the Heart01:27

Development of the Heart

3.1K
The development of the human heart, a crucial organ, commences from the mesoderm on the 18th or 19th day after fertilization. This process initiates in the cardiogenic area, a group of mesodermal cells at the embryo's head end, which evolves into elongated strands known as cardiogenic cords. These cords undergo a transformation to form hollow-centered endocardial tubes.
As the embryo undergoes lateral folding, these paired tubes approach each other, merging into a single primitive heart...

Summary
This summary is machine-generated.

Premature birth impacts infant brain development, causing changes in the lateral ventricles and deep grey matter structures like the putamen and thalamus. These ventricular abnormalities are linked to altered subcortical development in preterm neonates.

Area of Science:

  • Neuroimaging
  • Developmental Neuroscience
  • Pediatric Radiology

Background:

  • Premature birth affects subcortical development and brain morphology.
  • Neuroimaging studies reveal changes in deep grey nuclei and the ventricular system in preterm infants.
  • Multivariate tensor-based morphometry (mTBM) is a novel method for assessing brain structure deformation.

Purpose of the Study:

  • To investigate ventricular abnormalities in preterm neonates using mTBM.
  • To analyze the spatial relationship between lateral ventricles and surrounding subcortical structures.
  • To identify individual differences in brain structure pose (translation, rotation, scale).

Main Methods:

  • Comparison of surface morphometry and relative position of lateral ventricles between full-term and preterm neonates.
  • Application of multivariate tensor-based morphometry (mTBM) for precise local surface deformation measurement.
  • Relative pose analysis to detect individual variations in brain structure orientation and size.

Main Results:

  • Significant alterations found on the frontal horn and body of the left ventricle, and temporal horn of the right ventricle in preterm neonates.
  • Preterm infants showed a significant shift in the rotation of the left ventricle.
  • Correlations identified between lateral ventricle morphology/pose and the putamen and thalamus.

Conclusions:

  • Regional abnormalities in ventricular surface and pose are associated with altered development of the putamen and thalamus.
  • mTBM and pose analysis provide complementary information on white and grey matter growth.
  • Findings suggest a pattern of neural and cellular dysmaturation in preterm infants.
