Meanings and functions of different types of heart images in the communication of doctors and patients.

Images in medical communication are appreciated by both professionals and patients, but we know little about how they are actually used in clinical practice and in the learning processes of patients. This qualitative study investigates the use and the meaning potential of two different types of heart images: the hand-drawn doctor's sketch and the digital illustration from the web. The analysis starts with how these are recontextualised in social media, tracks them back to their original contexts and finally explores their material resources. The analytical perspective is that of social semiotics and multimodal discourse and interaction analysis. While the hand-drawn sketch is recontextualised as a witness of the specific consultation, the digital illustration is used to focus on the heart defect as such. It is also shown how the act of drawing works as a means for framing and structuring the consultation, slowing down the pace and reducing context and detail and thus focussing on what is uniquely relevant. While the digital and more realistic illustration is technically neutral and objective and is free from unique context, the drawing on paper is physically tied to its context of origin, which is also its main resource.
