Answer

Compared with anterior-posterior positioning, anterior-lateral positioning resulted in successful cardioversion with less mean energy (65 ± 13 vs 77 ± 13 J) and fewer mean shocks (1.48 ± 1.01 vs 1.96 ± 1.00 J). In addition, cardioversion occurred with the first 50-J shock in 73% of patients when anterior-lateral positioning was used, versus 36% with the anterior-posterior electrode position. [15]
