An evaluation tool for wave delineation in ECG processing: Wxw

2022 17th Iberian Conference on Information Systems and Technologies (CISTI) (2018)

Evaluating research results is not always an easy task. Although it is interesting to compare personal achievements against similar works from other researchers, in many ocassions it is hard to replicate exactly the same conditions, because papers do not reflect all the variables of the context. To mitigate this problem, some standard systems have been created for researchers to unify this step in their works. One example of this is the bxb (beat-by-beat) tool from PhysioNet's PhysioToolkit, developed to compare results in beat detection. Delineation is an important part inside Electrocardiogram (ECG) diagnostic systems, because it is necessary to properly identify waves inside the beats. Besides the position of each wave into the signal, onset and offset positions for a wave are also needed. The more precise these positions are, the better the diagnostic is. But unlike the case of the beat detection, there are no generic tools for delineation evaluation, and papers that deepen in this subject in most cases do not explain clearly how they get their results, or directly asked an expert to supervise the outcome of their systems. Because of this, the main purpose of the present work is to introduce an evaluation tool, named wxw, to assess wave delineation for a computer-aided ECG diagnostic system.

Abstract 13145: Mixed Digital Model of Care in Real-Time for Mexican Patients With Heart Failure

Circulation (2022)

Carlos J Guízar Amada Álvarez ANTONIO JORDAN Arturo J. Méndez Juan Carlos de la Fuente Mancera

Introduction Decompensated heart failure (DHF) is the main cause of cardiovascular hospitalization. During 1-year follow-up (FU), at least one rehospitalization occurred in 56.6% of patients with HF. In Mexico, HF places great burden on patients, caregivers, and healthcare systems. New strategies are essential for early diagnosis and treatment of DHF. Hypothesis: Use of a digital tool is effective for remote monitoring of patients with CHF to reduce the number of hospitalizations and/or unscheduled visits to the ER. Methods: A mixed digital model of HF (MDM-HF) care has been developed. It included an app in patient’s mobiles (CardioEnlace) that allowed real time monitoring of key parameters. These data were transferred into HF Unit portal and integrated into the patient's clinical file. CardioEnlace allowed detection of decompensation events through 1) alerts by patient′s text messages and 2) system alerts when variables were out of security limits on three or more consecutive days. If a patient showed signs of DHF, he/she was reached to provide medical instructions and/or scheduled an early appointment. Results: MDM-HF care was deployed in July 2021. Up to date 131 patients have been included. The median of age is 58 years (interquartile range 47.5-65.5) and 77.1% were male. Cardiovascular risk factors (CVRF) frequencies are shown in Table 1. HF was secondary to ischemic condition in 44.5% of the patients. At least one hospitalization in the previous 2 years was reported in 73.5% of the subjects. Cardio Enlace parameters are shown in Fig 1. A blood pressure <140/90 mmHg was reported in 89.5% of patients and the average exercise time was 32 min/day. CardioEnlace alerts from January 2022 to date, were 82. Reasons are shown in Table 2. Adjustments to the treatment were done immediately and none of the patients had been hospitalized. Discussion: MDM-HF care model supports an early detection of DHF and monitorization of CVRF treatment which affect around 50% of the patients. Follow-up evaluations would allow to assess its impact on hospitalizations/emergency admissions. MDM-HF care model is part of the HF National Mexican Registry that will integrate data-driven solutions to reduce lead times from diagnosis to therapy adjustments and reduce the economic burden of DHF.

ECGDT: a graphical software tool for ECG diagnosis

Multimedia Tools and Applications (2023)

Víctor Mondelo Marı́a J. Lado Arturo J. Méndez

Abstract While cardiovascular diseases are the leading causes of death in developed countries, detection of cardiac abnormalities can reduce mortality rates, through early and accurate diagnosis. One of the main assets used to help in the diagnosis process is the electrocardiogram (ECG). A free software tool for electrocardiogram analysis and diagnosis is presented. The tool, named ECGDT, allows: (1) to detect beats present on the ECG, both in single and multi-channel levels, (2) to identify beat waves, and (3) to diagnose different cardiac abnormalities. System evaluation was performed in two ways: (1) diagnostic capabilities were tested with Receiver Operating Characteristic (ROC) analysis, and (2) Graphical Software Interface (GUI) aspects, such as attraction, efficiency, or novelty, were evaluated employing User Experience Questionnaire (UEQ) scores. For disease diagnosis, the mean Area Under the ROC Curve (AUC) was 0.821. The system was also capable of detecting 100% of several cardiac abnormalities, such as bradycardia or tachycardia. Related to the GUI, all usability estimators scored values ranged between 2.208 and 2.750 (overall positive evaluations are obtained for values over 0.8). ECGDT could serve as an aid in the diagnosis of different medical abnormalities. In addition, the suitability of the developed interface has been proven.

Utility of platelet- to lymphocyte ratio as an inflammatory biomarker in major burns. our experience

Journal of Anesthesia & Critical Care Open Access (2025)

Dayamí Zaldívar Castillo Norton Pérez Carlos Lora Buelvas Arturo J. Méndez F Reyes

Background: Burn injuries are a major cause of morbidity and mortality, because of the severe local and systemic response developed, affecting organics functions. A decline in platelets and lymphocyte count compromise the immune response and patient´s outcome. To evaluate the usefulness of platelet to lymphocyte ratio as a biomarker of mortality in severely burned patients, the present research was performed. Methods: A descriptive, longitudinal, prospective study was carried out at the Burn Department of Calixto García Hospital, La Habana, from January 2022 to December 2023. All admitted patients with major burns, ages between 19 and 60 years old, and less than 24 hours since the beginning of the trauma, were included. Blood samples were taken on days 3 and 6 after injury, to determine platelet to lymphocyte values, and a relationship between the mortality rate and presence of complications was established. Results: 143 burned patients were included, males were predominant (63 %), flame (98.2 %) was the first causal agent and accidents (89.6 %) were the main production mode. 90 % of patients survived. Platelet-to-lymphocyte ratio values were lower in patients who developed complications and in the nonsuvivors group. Conclusion: Platelet to Lymphocyte ratio is an effective biomarker for predicting mortality in severely burned patients.
