Geng Xiake, a character in the Japanese comic book Rent a Girlfriend and its derivative works, has a much slower congenital heart rate than normal people, and starts to rent a girlfriend in order to find someone who can make his heart beat faster.
After discovering her attitude towards He Qian at a social gathering, Xuanxia felt that harmony was the "heart-pounding existence" she was pursuing, so she began to pursue him.
Suffering from arrhythmia, the heart beat rate in one minute is 60, which is much less than that of ordinary people.
Therefore, strenuous exercise and excitement in summer childhood can cause dizziness and dyspnea.
