We started making this app with the goal of creating an ECG question book with as many questions as possible, but creating over 1,100 questions was a painstaking task. We paid particular attention to ensuring that the explanations were reproducible and could be read using the same interpretation method. We worked hard for those who want to learn about ECGs and for those who love ECGs. We hope that this will be of help in your future medical practice.
