According to the same report, AFIB prevalence is expected to rise to 12.1 million in 2030. In 2010, the estimates of the prevalence of AFIB in the United States ranged from 2.7 million to 6.1 million. ![]() Recent reports from the American Heart Association 1 outlined that, in 2015, AFIB was the underlying cause of death for 23,862 people and was listed on 148,672 US death certificates. It is associated with a significant increase in the risk of severe cardiac dysfunction and stroke. The most common and pernicious arrhythmia type is atrial fibrillation (AFIB). There are several dozen such classes with various distinct manifestations such as excessively slow or fast heartbeats (sinus bradycardia (SB) and atrial tachycardia (AT)) and irregular rhythm with missing or distorted wave segments and intervals (premature ventricular contraction (PVC)). Arrhythmias represent a family of cardiac conditions characterized by irregularities in the rate or rhythm of heartbeats. Other portions of the signal include the PR, ST, and QT intervals. 1) consists of a sequence of waves, a P-wave presenting the atrial depolarization process, a QRS complex denoting the ventricular depolarization process, and a T-wave representing the ventricular repolarization. The ECG graph of a normal beat (shown in Fig. The dataset can be used to design, compare, and fine-tune new and classical statistical and machine learning techniques in studies focused on arrhythmia and other cardiovascular conditions.Īn ECG is a graph of voltage with respect to time that reflects the electrical activities of cardiac muscle depolarization followed by repolarization during each heartbeat. The dataset consists of 10-second, 12-dimension ECGs and labels for rhythms and other conditions for each subject. Thus, we collected and disseminated this novel database that contains 12-lead ECGs of 10,646 patients with a 500 Hz sampling rate that features 11 common rhythms and 67 additional cardiovascular conditions, all labeled by professional experts. Advancement of modern machine learning and statistical tools can be trained on high quality, large data to achieve exceptional levels of automated diagnostic accuracy. This practice, however, generates large amounts of data, the analysis of which requires considerable time and effort by human experts. As a non-invasive test, long term ECG monitoring is a major and vital diagnostic tool for detecting these conditions. Certain types of arrhythmias, such as atrial fibrillation, have a pronounced negative impact on public health, quality of life, and medical expenditures. This newly inaugurated research database for 12-lead electrocardiogram signals was created under the auspices of Chapman University and Shaoxing People’s Hospital (Shaoxing Hospital Zhejiang University School of Medicine) and aims to enable the scientific community in conducting new studies on arrhythmia and other cardiovascular conditions.
