Anti-Dysrhythmics in the ICU

In this lecture from the ResusX: Reset conference (see link below for more lectures), Dr. Max Hockstein discusses the use of antidysrhythmics in the ICU, focusing on their history, mechanisms, and practical application.

He begins with a historical overview, highlighting key milestones such as the discovery of lidocaine’s effects in 1950 and the development of the Vaughan Williams classification scheme in the 1970s. Dr. Hockstein emphasizes the complexity and limitations of current antidysrhythmic classifications, referencing the Sicilian Gambit and its focus on arrhythmia mechanisms rather than drug mechanisms.

He details the properties and side effects of commonly used drugs like amiodarone and procainamide, stressing the importance of choosing the right drug for the duration of the illness. Finally, he underscores the significance of treating the underlying conditions causing arrhythmias rather than the arrhythmias themselves, advocating for a nuanced, physiology-based approach to critical care.
