Multiprofessional Critical Care Review: Adult (2023)-8: Analysis and Therapy of Ventricular Arrhythmias (Sammy Zakaria, MD, MPH)

Video Transcription

Video Summary

In this video, the speaker discusses the analysis and therapy of ventricular arrhythmias. They begin by discussing the epidemiology and significance of ventricular arrhythmias in the ICU environment, noting that they occur in 2.2% of ICU patients and are associated with increased mortality rates. They then focus on differentiating ventricular tachycardias from supraventricular tachycardias and distinguishing between monomorphic and polymorphic ventricular tachycardia. The speaker emphasizes the importance of determining the underlying cause of ventricular arrhythmias, such as cardiac ischemia, electrolyte abnormalities, or medication/substance use, and addressing these causes in the treatment approach. In terms of therapy, the speaker recommends immediate treatment for hemodynamically unstable ventricular arrhythmias using medications such as amiodarone, lidocaine, or procainamide, and possible cardioversion. They also discuss the use of beta blockers or magnesium therapy for stable ventricular tachycardia. The speaker concludes by highlighting the importance of prompt treatment and identification of ventricular arrhythmias and the need for further evaluation and management by an electrophysiologist in some cases. References and contact information for further questions are provided at the end.
