Connecting appliances to an Arduino

Hello all,

I am an Industrial design student in the Netherlands and I am starting my way up the Arduino line. I have a project in my mind which I am not sure if it is possible to realise with on Arduino platform. My question is as follows: Is it possible to connect different appliance ( an ECG device or/and a blood pressure device) to an Arduino platform and have the results on an external screen,connected to the Arduino.

I would much appreciate if somebody can answer my question.

Kind Regards, :) :)

It depends on the specifics of the input and what sort of display.

There's not enough information to answer the question.

The different appliance ( an ECG device or/and a blood pressure device) have external interface that send out the results? RS232? I2C? SPI?

What type of an external screen that connected to the Arduino?
