Based on a personal computer, it acquires ECG (electrocardiography), respiratory, and blood pressure signals for each step of a mental stress trial. The collected data are then processed and spectral analysis is carried out by conventional FFT. In addition, an autoregressive identification algorithm computes the power and central frequency of the spectra peaks, allowing automatic classification of low-frequency (LF) and high-frequency (HF) peaks. The analysis executed for each step of the trial allows the comparison of the various spectral responses corresponding to different stimulations. This system was tested on 32 recently infarcted subjects and results show a significant increment in LF peak (P>","is_dataset_classified":null,"base_score":3.8712010109078907,"endowment":3.8712010109078907,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19767382","pmcid":null,"openalex_id":"https://openalex.org/W1597085728","authors":[],"funders":[],"total_grants":0,"fwci":10.053,"citation_percentile":0.98879367,"influential_citations":0,"citation_trend":[{"year":2013,"count":2},{"year":2014,"count":3},{"year":2016,"count":1},{"year":2017,"count":1},{"year":2022,"count":2}],"oa_status":"closed","license":null,"oa_locations":[{"url":"https://doi.org/10.1109/cic.1989.130598","host_type":""}],"fields_of_study":["Heart Rate Variability and Autonomic Control","Non-Invasive Vital Sign Monitoring","EEG and Brain-Computer Interfaces"],"mesh_terms":[],"keywords":["Heart rate variability","Mental arithmetic","Mental stress","Spectral analysis","Fast Fourier transform","Heart rate","Autoregressive model","Stress (linguistics)","Speech recognition","Electrocardiography","Computer science","Respiratory rate","Balance (ability)","Artificial intelligence","Blood pressure","Pattern recognition (psychology)","Mathematics","Statistics","Algorithm","Psychology","Cardiology","Medicine","Internal medicine","Neuroscience","Physics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Quality Education"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-09T09:47:26.317146Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
