Feasibility, safety, and comfort of the '2BB' (2 cm below the bra) position of insertable cardiac monitors in women: the IN-WOMEN-ICM pilot study

Abstract

The left panel depicts a female thorax in supine position, highlighting the 2 cm below the underwire bra (2BB) inframammary insertion and chest X-ray images of a patient with the device inserted in the proposed position. The middle panel shows boxplots with median, Q1, Q3, Min, and Max values for the R-wave amplitude at insertion, wound follow-up, and end of follow-up (left axis) and the percentage of patients for whom P-waves were visible at standard resolution at insertion, wound follow-up, and end of follow-up (right axis), and an electrocardiogram recorded by a device implanted in the 2BB position. The right panel shows mean scores for each questionnaire item (0 = not at all, 5 = very much).
