J wave detection algorithm of the BCG in chair and bed using continuous spline wavelet transform
Flores Nuñez, Laura; García Limón, José Alberto; Martínez Suárez, Frank; Casanella Alonso, Ramón; Alvarado Serrano, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Comunicació de congrés
Accés obertThis study presents an algorithm for unsupervised beat-to-beat detection of the J-wave of the ballistocardiogram (BCG) in records of both lying (bed) and seated (chair) persons. The algorithm is based on the continuous ... -
Long-term continuous ambulatory ECG monitor with Beat-to-Beat Heart Rate Measurement in Real Time using ESP32
Martínez Suárez, Frank; García Limón, José Alberto; Rivera Córdova, Dalila; Flores Nuñez, Laura; Casas Piedrafita, Óscar; Alvarado Serrano, Carlos (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés obertThis work presents a long-term continuous ambulatory ECG monitor for simultaneous acquisition and storage of leads DI, aVF, and V2, and beat-to-beat R wave detection using wavelet transform for heart rate measurement in ... -
Low-power long-term ambulatory electrocardiography monitor of three leads with beat-to-beat heart rate measurement in real time
Martínez Suárez, Frank; García Limón, José Alberto; Baños Bautista, Jorge Enrique; Alvarado Serrano, Carlos; Casas Piedrafita, Óscar (Multidisciplinary Digital Publishing Institute (MDPI), 2023-10-08)
Article
Accés obertA low-power long-term ambulatory ECG monitor was developed for the acquisition, storage and processing of three simultaneous leads DI, aVF and V2 with a beat-to-beat heart rate measurement in real time. It provides long-term ... -
Novel indices of ventricular repolarization to screen post myocardial infarction patients
Alvarado Serrano, Carlos; Ramos Castro, Juan José; Pallàs-Areny, Ramon (Elsevier, 2006-05)
Article
Accés obertWe propose novel indices of ventricular repolarization intervals, the JTp/JT, Tpe/JTp and Tpe/JT ratios. These indices have been compared with the duration of the ventricular repolarization intervals and other ratios in ... -
Robust algorithm for the detection and classification of QRS complexes with different morphologies using the continuous spline wavelet transform with automatic scale detection
Martínez Suárez, Frank; Alvarado Serrano, Carlos; Casas Piedrafita, Óscar (Institute of Physics (IOP), 2024-01-10)
Article
Accés obertThis work presents an algorithm for the detection and classification of QRS complexes based on the continuous wavelet transform (CWT) with splines. This approach can evaluate the CWT at any integer scale and the analysis ... -
Spatial variability of ventricular activity intervals in normal subjects and old myocardial infarction patients
Alvarado Serrano, Carlos; Ramos Castro, Juan José; Pallàs-Areny, Ramon (Institute of Electrical and Electronics Engineers, 2004-06)
Text en actes de congrés
Accés obertIncreased dispersion of QT interval in the 12-lead ECG have been proposed as risk factor of ventricular arrhythmias in post myocardial infarction (post-MI) patients, but its sensitivity and specifity is low for diagnosis ...
