This chapter presents a systematic approach to the diagnosis and acute management of hemodynamically significant dysrhythmias and pulseless arrest states. An overall approach to the unstable patient is reviewed with a specific focus on cardiac conduction and the effects of hemodynamics. By undertaking assessment of the pulse and clinical stability of the patient, the rate and regularity of the rhythm, and the QRS morphology, the clinician can make rational assessments to guide evidence-based therapeutic interventions and avoid the risks of inappropriate treatments. Furthermore, this chapter discusses the transition from stable to unstable to pulseless rhythms and the appropriate treatment for each.
