A publicly available 12-lead electrocardiogram criti-cal value dataset covering 13126 records

This project collected 13,126 12-lead electrocardiogram (ECG) records from the First Affiliated Hospital of Zhengzhou University from June 2015 to November 2024, and constructed the ZZU-ZUA ECG critical value database. The ECG records in this database were from 9,785 patients, with recording durations ranging from 7 to 198 seconds, a sampling rate of 500 Hz, and covering 15 types of critical arrhythmias. All samples were labeled and verified by professional physicians. This database can be directly used for research related to arrhythmia detection.
