Cardiac complications are caused by an unbalanced diet, the consumption of alcohol, smoking tobacco, in addition to the excess of polluting gases such as carbon dioxide (CO2), among other gases that are harmful to the human body, due to these types of problems, they arise more frequently in people, which lead to heart problems at an early age. An optimal prevention of these cardiac abnormalities is necessary using an Electrocardiogram (ECG), by using this equipment it is possible to detect the cardiac anomalies that the person may have, thus giving early prevention for cardiac abnormalities that may be occurring in the patient. The design of a low-cost ECG will be considered using the AD8232 module, which allows recording the electrical activities of the heart, obtaining an ECG using the Arduino, in addition the Bluetooth module will send the data collected from the ECG from a patient to a cellphone which will store this information, to be later analyzed by a cardiologist. This paper is intended for use in health campaigns, given that according to the Pan American health organization, 70% of deaths in the world are due to heart problems, due to this figure, it is expected to reduce the rate with early prevention, which consists of the implementation of this biomedical equipment in health campaigns that will have the basic functionalities for the analysis of the electrocardiogram and that is low cost compared to biomedical equipment currently that provide the same functionalities.
