The invention discloses a single-guided heart stick data intelligent diagnosis cloud calculation system and a processing method thereof. The system comprises a client acquisition module, a storage service module, a message queue service module and a calculation service module, wherein the client acquisition module is used for acquiring long-term dynamic electrocardiogram (EEG) data of a single-guided heart stick, uploading the data to the storage service module and downloading required data from the storage service module, the storage service module is used for storing the long-term dynamic ECG data and the ECG analysis report, the message queue service module is used for realizing message transmission and function decoupling, the calculation service module is used for providing hardware resources required for calculation, an ECG scatter plot is drawn based on the long-term dynamic electrocardiogram data of the single-guided heart stick, an AI model is utilized to carry out artificialintelligence diagnosis of the ECG scatter plot, the classification result of the ECG scatter plot is calculated, and the ECG analysis report is formed. The system is advantaged in that on the basis ofstorage service and calculation service of the cloud service architecture, the analysis speed of the dynamic ECG and diagnosis accuracy are effectively improved.
