Insights
HeartSearcher aids clinical decisions by identifying patients with similar arrhythmias using regular expressions to summarize heartbeat patterns. This method significantly reduces data volume, improving arrhythmia analysis from long-term electrocardiogram data.
Area of Science:
- Biomedical Engineering
- Cardiology
- Data Science
Background:
- Long-term electrocardiogram (ECG) monitoring via mobile-linked Holter devices is common.
- Current systems primarily focus on arrhythmia detection, lacking clinical decision support.
- Efficient analysis of extensive ECG data remains a challenge.
Purpose of the Study:
- To develop a novel method for supporting clinical decisions in arrhythmia analysis.
- To identify patients with similar arrhythmias by comparing heartbeat patterns.
- To reduce the computational burden of analyzing large ECG datasets.
Main Methods:
- Summarizing typical heartbeat patterns into regular expressions for each patient.
- Ranking patients based on the similarity of their regular expression patterns.
- Utilizing the MIT-BIH arrhythmia database for validation.
Main Results:
- HeartSearcher successfully identifies patients with similar arrhythmias.
- The regular expression abstraction reduces heartbeat classification data volume by an average of 98%.
- Demonstrated potential for enhanced clinical decision-making.
Conclusions:
- HeartSearcher offers a significant advancement in analyzing long-term ECG data for arrhythmias.
- The pattern summarization technique drastically reduces data complexity.
- This approach holds great promise for improving clinical support systems in cardiology.
Abstract:
Long-term electrocardiogram data can be acquired by linking a Holter monitor to a mobile phone. However, most systems of this variety are simply designed to detect arrhythmia through heartbeat classification, and do not provide any additional support for clinical decisions. HeartSearcher identifies patients with similar arrhythmias from heartbeat classifications, by summarising each patient's typical heartbeat pattern in the form of a regular expression, and then ranking patients according to the similarities of their patterns. Results obtained using electrocardiogram data from the MIT-BIH arrhythmia database show that this abstraction reduces the volume of heartbeat classifications by 98% on average, offering great potential to support clinical decisions.
