Objectives: Thousands of people suffer from cardiovascular diseases. Despite the Electrocardiogram being a consolidated exam, the lack of methodological observation in the placement of sensors can compromise the results. This article proposes a wearable vest capable of conditioning cardiac signals from three simultaneous channels, reducing the chance of failures in the exam due to the smaller number of electrodes attached to the patient's body. Methods: It adds the vetocardiogram technique to the electrocardiogram wearable, which consists of three orthonormal leads Vx, Vy, and Vz, measuring dynamic components of the heart vector. Results: Display of the cardiac biopotential in the web-mobile application satisfactorily represents the visualization of the twelve leads synthesized from the Dower transform, as well as the spatial projections of the cardiac loop under a three-dimensional view. Conclusion: Feasibility of integrating the vetocardiogram with the electrocardiogram exam.
