Figure 1: Bar graph representing patient throughput in the pre-adoption and post-adoption cohorts. “Pre-Adoption” is defined as the time frame where LET monitoring or a combination of LET monitoring and esophageal deviation was employed. “Post-Adoption” is defined as the time frame when proactive cooling alone was used to protect the esophagus. The switch to proactive esophageal cooling was associated with a 43.5% increase (P < 0.0001) in EP lab throughput.
