Figure 2. Dynamic changes in QTc occurring over first 24 hours post-LCSD.

Figure 2

Temporal values of QTc values showing dynamicity over time. Average values at each time point are shown along with standard error of the mean unless otherwise mentioned.

Panel A. Overall cohort changes in average QTc and average HR following LCSD (±SD).

Panel B: Comparison of QTc fluctuations post LCSD in subgroup with transient increase in QTc > 30 ms from baseline (filled circles) versus the rest of the cohort without such an increase (open circles).

Panel C: Comparison of QTc fluctuations post LCSD in subgroup with transient decrease in QTc >30 ms from (filled circles) versus the rest of the cohort without such a decrease (open circles).

Panel D: Comparison of QTc fluctuations post LCSD in subgroup with both a transient increase and decrease in QTc >30 ms from baseline (filled circles) versus the rest of the cohort without such an increase/decrease (open circles).

* Asterix above mean value denotes a statistically significant difference between the means at a given time point (rank sum analysis at each time point was used); p value < 0.05 was considered statistically significant.
