Figure 2. Changes in troponin I from pre- to post-cardioversion as plotted against cumulative energy in Joules (A) and Left Ventricular Mass (B).
When the change in cardiac troponin I from pre- to post-cardioversion is plotted against cumulative energy delivered during cardioversion (Figure 2A) and LV Mass (Figure 2B) there was no significant relationship amongst the small changes observed (r=0.137, p=0.306 and r=0.125,p=0.412 respectively). However, in the cardiomyopathy group (Figure 2 - grey) there are a few select cases that showed significant reductions in cardiac troponin I.
