Objetivo: Doenças cardíacas são a principal causa de morte globalmente, e o eletrocardiograma (ECG) é a principal ferramenta para avaliar a atividade cardíaca. O diagnóstico automatizado e remoto do ECG pode ajudar o sistema de saúde com avaliações cardíacas antecipadas e precisas, especialmente em regiões periféricas e áreas rurais. A classificação automática de ECG foi amplamente pesquisada, mas ainda é um desafio criar modelos precisos para um espectro tão amplo. Método: Este estudo aprimora o desempenho dos modelos de classificação de aprendizagem profunda de ECG usando um estágio de pré-treinamento multimodal com o laudo médico. Resultados: Nossa abordagem melhora o modelo estado-da-arte e atinge uma pontuação média de F1 de 0,755 em seis categorias usando o conjunto de dados completo, o que é uma melhoria relevante para um corpus não-rotulado relativamente grande. Conclusão: Os resultados demonstram o potencial de melhora da avaliação cardíaca automatizada com o pré-treinamento de texto.
