Modelos murinos permitem estudar os principais mecanismos da arritmogênese. Para isso, cardiomiócitos de alta qualidade são necessários para a realização de medidas de patch-clamp. Aqui, é descrito um método para isolar miócitos murinos atriais e ventriculares via perfusão retrógrada de Langendorff baseada em enzimas, que permite medidas simultâneas de transientes de cálcio e corrente de cálcio tipo L.
