Fifty years ago, I worked in the First Rehabilitation Hospital of Shaanxi Province (now Baoji Central Hospital). One day in 1973, the hospital librarian I was close to told me about a new magazine called Cardiovascular Diseases. In the midst of a decade of turmoil, the medical community, like other academic circles, was silent, most academic journals were closed, and hospital libraries were half-closed and half-open. I heard that there was a new magazine, again about cardiovascular disease, so I couldn't wait to borrow it and read it from start to finish. It is known from the introduction that "Cardiovascular Diseases" is edited by Academician Wu Yingkai, a famous cardiovascular scientist and president of Fuwai Hospital of Chinese Academy of Medical Sciences. This was the only specialist magazine of cardiovascular diseases in China at that time. In the era when there were no books to read, I looked forward to the quarterly issue of Cardiovascular Diseases magazine to arrive as scheduled, draw knowledge and nutrition from it, and have formed an indissolvable bond with it since then. Although, due to the historical environment at that time, there was almost no research work in China, and many spaces in the magazine introduced foreign progress, we, who have been isolated from the outside world for seven or eight years, are also quite interested in these contents. The journal also published some treatises and articles, mainly focusing on case summary, diagnosis and treatment experience, and retrospective analysis, which have clinical reference value. The electrocardiogram analysis of one case in each issue presided over by Professor Sun Ruilong attracted me even more, and I learned a lot of knowledge and skills in the diagnosis and analysis of complex arrhythmias.
