This paper describes the design and implementation of a wireless electrocardiographic monitoring system for Android devices. The system consists of a device that will act as a server located in the patient and another device that will act as a client. The server incorporates the stages of protection against external defibrillators, acquisition and transmission of the signal through a Wi-Fi module (ESP8266 NodeMCU), and the client receives, processes and displays in real time the electrocardiogram (ECG) signal in a smartphone or an electronic tablet, with Android operating system. In addition, it calculates and displays the RR series from ECG and two diagnostic indicators with a delay of less than two seconds. The experimental tests of the prototype with seven volunteers showed the excellent performance of the proposed protocol for the application layer of the system and the fulfillment of the established design requirements and criteria. The system allows registering the ambulatory ECG within a range of up to 15 m and is an excellent alternative to increase the quality of life of the elderly or other people who present problems for locomotion (temporary or permanent).
