Following the success of the first volume of the EHRA Book of Pacemaker, ICD and CRT Troubleshooting a second volume with new cases has now been developed. A timely addition to the European Society of Cardiology, as device therapy has seen many new developments since the first volume, with the advent of leadless pacing, conduction system pacing, and subcutaneous ICDs, amongst other novelties. These new technologies are covered in the book, as are general device troubleshooting issues which were not presented in the first volume. Maintaining an identical format for the cases in this volume, which are arranged in separate sections on pacing (27 cases), ICDs (23 cases), and CRT (20 cases), each section is arranged in a logical manner to guide the reader and help build on knowledge gained from reading the previous cases. As with the first volume, the content will help those planning on sitting the EHRA Cardiac Pacing exam. There is significant detail regarding specific algorithms of different device manufacturers that will also appeal to general cardiologists, nurses, and allied professionals performing device follow-up. As with the first volume, this book will serve not only to further your technical knowledge, but also to sharpen your skills of observation and reasoning.
