Study Notes

Cardiac Arrhythmias

  • Antiarrhythmic drugs with a narrow therapeutic window may induce proarrhythmia.
  • The two major mechanisms of cardiac arrhythmias are abnormal impulse generation and abnormal impulse conduction.
  • Arrhythmia can be induced by electrolyte imbalance, particularly hypokalemia.

Treatment of Arrhythmias

  • The preferred therapy for arrhythmia is cardioversion, when possible.
  • Normal heart rate in a person with sinus rhythm is between 60-100 beats per minute.

Antibiotics

  • Protein synthesis inhibitors are a type of antibiotic that inhibits bacterial replication.
  • The primary requirement for selecting the most appropriate antimicrobial agent is the susceptibility of the causative organism.
  • The primary concern associated with the most commonly used antibiotics is the development of resistance.
  • The key factor required for selecting the most appropriate antimicrobial agent is the identification of the causative organism.
  • Examples of protein synthesis inhibitors include tetracycline, macrolides, and aminoglycosides.
