The China Physiological Signal Challenge 2018: Automatic identification of the rhythm/morphology abnormalities in 12-lead ECGs

Invitation Letter (in English)        Invitation Letter (in Chinese)

*Please be noted the following submission deadline:

1.Before September 24, each team has the opportunity to submit entries up to 5 times, and the score will be updated in the system soon;
2.During September 25 to October 1, each team could have another 2 submission opprotunities to improve the entries based on previous results.


1. 参赛团队9月24日前可以使用最多不超过5次机会提交程序,组委会会尽快给出反馈结果;
2. 参赛团队在9月25-10月1日期间可以有2次新的提交机会,以根据前期结果重新组合优化程序。

Good news! The Scores of some entries come out as shown below. More will be coming soon…

Please note the scores are based on 450 samples randomly picking from the test set (50 samples from each type).
The reasons for this evaluation are from two aspects:
1) to reduce the evaluation burden and give timely feedback to the challenge teams so that they can optimize the model as soon as possible;
2) to prevent challengers frequently testing the parameter effects on the final test database.
In the late stage of the challenge (before deadline), Each team will be asked to confirm the final code version they want to be evaluated, and will run the code on the whole test database, which will generate the final challenge results and ranking.

The China Physiological Signal Challenge (CPSC) 2018 is the 1st China Physiological Signal Challenge, which will be held during the 7th International Conference on Biomedical Engineering and Biotechnology (ICBEB 2018) in Nanjing, China. The CSPC aims to provide a platform for the open-source data and algorithms for the physiological signal analysis, and thus to promote the open-source research pattern for the cardiovascular disease detection and prediction in China.
The CPSC2018 aims to encourage the development of algorithms to identify the rhythm/morphology abnormalities from 12-lead ECGs, lasting several seconds to tens of seconds. The 12-lead ECGs used in CPSC 2018 include one normal type and eight abnormal types, which are detailed as:
(1) Atrial fibrillation (AF)
(2) First-degree atrioventricular block (I-AVB)
(3) Left bundle brunch block (LBBB)
(4) Right bundle brunch block (RBBB)
(5) Premature atrial contraction (PAC)
(6) Premature ventricular contraction (PVC)
(7) ST-segment depression (STD)
(8) ST-segment elevated (STE)

Challenge Data
The challenge ECG recordings were collected from 11 hospitals. The training set contains 6,877 (female: 3178; male: 3699) 12 leads ECG recordings lasting from 6 s to just 60 s (see Table 1) and the test set contains 2,954 ECG recordings with the similar lengths. The test set is unavailable to the public and will remain private for the purpose of scoring.
ECG recordings were sampled as 500 Hz. All data are provided in MATLAB format (each recording is a .mat file containing the ECG data, as well as the patient sex and age information). More details of the training set can be seen in Table 1. Figure 1 shows an example 12-lead ECG waveforms.
There is a REFERENCE.csv file for the training data to provide the labels for each recording. The majority of the recordings only have one labeling (denoted as First label). However, a few recordings have up to three labels (denoted as First label, Second label and Third label respectively). For example, the recording of A0043 has two labels: First label 5 and Second label 2, indicating that this recording is identified as both RBBB and AF. If your code gives either of these two judgments, it is right for classification.

Since the size of the whole training set is large, we seperate the training set as three sub-sets. You can download them respectively and imerge them in one training set file. For detailed training data, please download from Training Set 1, Training Set 2, and Training Set 3.

The scoring for CPSC2018 uses a F1 measure, which is an average of the nice F1 values from each classification type. The counting rules for the numbers of the variables are defined in Table 2 as below:
Table 2: Counting rules for the numbers of the variables.
STE N91N92N93N94N95N96N97N98N99N9x

For each of the nine types, F 1 is defined as:
Normal: F11=2 × N11N1x + Nx1                       AF: F12=2 × N22N2x + Nx2                       I-AVF: F13=2 × N33N3x + Nx3                       LBBB: F14=2 × N44N4x + Nx4

RBBB: F15=2 × N55N5x + Nx5             PAC: F16=2 × N66N6x + Nx6             PVC: F17=2 × N77N7x + Nx7            STD: F18=2 × N88N8x + Nx8            STE: F19=2 × N99N9x + Nx9

The final challenge score is defined as follows:

F1=F11  +  F12   +  F13   +  F14   +  F15   +  F16   +  F17   +  F18   +  F199

In addition, we also calculate the F1 measures for each of the four sub-abnormal types, i.e., the AF, block, premature contraction and ST-segment change, as follows:

AF: FAF=2 × N22N2x + Nx2                                                                         Block: FBlock=2 × (N33   +  N44   +  N55   )N3x + Nx3 + N4x + Nx4 + N5x + Nx5

Premature contraction: FPC=2 × (N66   + N77   )N6x + Nx6 + N7x + Nx7                    ST-segment change: FST=2 × (N88   +  N99   )N8x + Nx8 + N9x + Nx9

Participating in the challenge
To participate in the challenge, you will need to submit a software written by Matlab or Python that is able to run on the test data and output the final classification result without user interaction in our test environment. One sample entry ‘CSPC2018_challenge.m’ (written in MATLAB) is available to help you get started. The team must submit the first challenge open-source entry before June 1, 2018. The deadline for submitting the challenge entries is October 1, 2018.
