"An excellent book.... extremely readable, well organised and illustrated with a large number of diagrams and ECG traces. There is certainly information suitable for beginners, but the more advanced reader is also likely to find something of value. I think it would prove a useful addition to any practice bookshelf and be read by veterinary nurses, students and vets alike." - Veterinary Times
