Abstract

The electrocardiogram (ECG) is the main diagnostic means to identify alterations in electrical conduction of the heart. Therefore, correctly interpreting the ECG is an essential but highly complex competency for health sciences students.

With the aim of facilitating the learning of electrocardiography in our students, a free access mobile application and validated content was developed. The creation process was completed in four phases: content development, validation with experts, software development and usability testing. The content was validated by five experts, reaching a content validity coefficient of .91 for clarity, .95 for accuracy, and .97 for relevance. The usability test was carried out by applying the Spanish version of the Computer System Usability Questionnaire (CSUQ) to 33 subjects from the nursing program, who scored: system quality 6.41/7, information quality 6.07/7, interface quality 6.55 /7 and general satisfaction 6.52/7.

The ECG para enfermería consists of four learning modules and a heart rhythm simulator for the identification of the main arrhythmias. Was published in 2021 and has reached more than forty countries.
