Handy EKG: A Low-Cost Electrocardiograph for Primary Care.

Background Cardiovascular diseases constitute the majority of noncommunicable disease deaths worldwide. In Honduras, cardiovascular diseases represent the fifth cause of death among individuals aged 45 to 49 years, while 20% of emergency room visits are due to cerebrovascular events, heart failure, and acute myocardial infarction. Methodology A low-cost three-lead electrocardiograph (ECG) (Handy EKG) was designed and manufactured for primary care. The device is supported by Bluetooth connectivity and machine learning. Device readings were collected from volunteers and compared to those obtained with a conventional 12-lead ECG. Results The device provided readings of lead one of a TDOU model CMS600G 12-lead ECG to monitor and diagnose bradyarrhythmia and tachyarrhythmias. Overall, 96% (49) of the readings showed a similarity in morphology, amplitude, and duration of waves, segments, and complexes compared to a 12-lead ECG. The device showed potential for application in primary care and intrahospital settings due to its continuous monitoring capabilities, portability, and possible connectivity with mobile devices. Conclusions The results indicate that the designed platform is safe, offers good quality in its operation at all levels, and provides ECG results equivalent to those of a conventional ECG in most cases (considering only one lead).

Colangiocarcinoma intrahepatico con manifestaciones clínicas atípicas: reporte de caso / Intrahepatic cholangiocarcinoma with atípical clinical manifestations, case report

El colangiocarcinoma es una neoplasia de la vía biliar, siendo el segundo cáncer hepático primario más frecuente en el mundo, con una incidencia del 2%. Predomina enhombres, la sobrevida en estados tempranos es de 40 meses con cirugíay 12 meses con quimioterapiaen estados mas avanzados.Objetivo:identificar manifestaciones clínicas no específicas, que orienten al médico a realizar un diagnóstico temprano del Colangiocarcinoma. Presentación del caso clínico: paciente masculino, en la sexta década de la vida, diabético, con historia de 18 meses de presentar fatiga y tos seca sin predominio de horario, durante el proceso diagnóstico se encontró hepatomegalia y anemia microcítica hipocrómica.La tomografía computarizada abdominal, reveló masa heterogénea en hígado. El resultado de los marcadores tumorales CA 19.9 y antígeno carcinoembrionario fueron normales.Conclusión: el colangiocarcinoma es un tipo de cáncer que se puede presentar con síntomas inespecíficos por lo que la sospecha clínica puede ser difícil y debe apoyarse en estudios complementarios...(AU)
