Study Notes

Arrhythmia Management

  • Applying an ice bag to the face can stimulate the vagus nerve and induce bradycardia.
  • IV adenosine can be used to induce bradycardia, and afterwards, treatment can continue with beta blockers, digoxin, or other anti-arrhythmic drugs.
  • Rapid IV adenosine administration is an anti-arrhythmic strategy to induce bradycardia.
  • In patients with cardiovascular compromise, synchronized cardioversion is the indicated treatment.

Pediatric Arrhythmias

  • Arrhythmias can occur in children, and their treatment options are available.

Bacterial Endocarditis

  • Bacterial endocarditis is a condition with specific symptoms, which are important to recognize for timely diagnosis and treatment.
