Query: Not for the medical student

Dale Dubin is a little too oversimplified. It takes too long to read and in the end one feels not having gathered enough. The book seems to be directed more towards paramedics.Medical students would be better of reading Hamptons ECG made easy. It is concise, yet comprehensive enough. It is easy to read and in a little over 70 pages.
