question: Coronaviruses are a common cause of colds and upper respiratory infections. COVID-19 is a derived disease caused by the new coronavirus that was identified in China in December 2019, which caused a global pandemic of respiratory diseases since 2020. The consequences of the pandemic were suffered by those countries whose hospitals did not have the right equipment to fight the virus. Indeed, Peru has 1.1 million cases due to the lack of clothing in sanatoriums. Additionally, in COVID, new electrocardiographic abnormalities that the patient may present should be considered as a differential diagnosis. In this way, the present project consists of developing a real-time cardiac wave transmitter of a wearable electrocardiograph connected to the audio input of a cell phone to another mobile device through the internet, with the purpose of being used in hospitals in Peru that do not have an ECG on hand. © 2021 IEEE.
