In this episode, we clarify key terms related to pacemakers (PPMs) and implantable cardioverter-defibrillators (ICDs). What do the common two-letter labels AR, VR, AS, VS, AP, VP, FD, TD, TP, CD, RV, and RT mean on EGM of an ICD? What is the relationship between the lower rate limit and the lower rate interval? What is the relationship between the post-ventricular atrial refractory period (PVARP) and the total atrial refractory period (TARP)? What is hysteresis? What is a typical upper tracking rate? What is fusion and pseudofusion? Tune in for answers to these questions.
