Dysrhythmias III: Characteristics of Dysrhythmias01:29

Dysrhythmias III: Characteristics of Dysrhythmias

709
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

1.2K
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...

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

47
Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Endocarditis I: Introduction01:25

Endocarditis I: Introduction

873
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis II: Clinical Features of Infective Endocarditis

929
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Area of Science:

  • Neonatal Medicine
  • Gastroenterology
  • Pediatric Surgery

Background:

  • Necrotizing enterocolitis (NEC) is a leading gastrointestinal emergency in premature infants.
  • The etiology of NEC is multifactorial, involving prematurity, feeding, hypoxia-ischemia, and bacterial colonization.
  • Advances in understanding neonatal NEC have been made, yet its exact cause remains elusive.

Observation:

  • A 35-week preterm infant experienced recurrent supraventricular tachycardia.
  • The infant developed NEC during the second week of life.
  • This clinical presentation suggests a potential link between supraventricular tachycardia and NEC in preterm infants.

Findings:

  • The case report details the development of NEC in a preterm infant with a history of supraventricular tachycardia.
  • It highlights the critical risk factors associated with NEC, including prematurity and feeding practices.
  • The occurrence of NEC in this specific clinical context warrants further investigation.

Implications:

  • This case emphasizes the importance of cautious enteral feeding strategies for high-risk premature infants.
  • It suggests that infants with conditions like supraventricular tachycardia may be particularly vulnerable to NEC.
  • Further research is needed to elucidate the relationship between cardiac arrhythmias and NEC pathogenesis.
