ZigBee is going into health arena, but I think not for streaming live
patient data like ECG, but more with home care devices for transmission
of sparse data, like non-ivasive blood pressure or heart rate etc...

I made some applications with IEEE802.15.4 for acquiring live data from
patient. It was done with LPC21xx and chipcon/TI radio chip connected
via SPI. Protocol was not zigbee, but based on 802.15.4, optimized for
such application. Ideal raw data rate is 250kbit (at 4,2GHz) That's
enough for basic 3 lead ECG, which is common monitoring configuration.
LPC2000 is OK for running wireless protocol, some basic data
acquisition/processing (like heart rate detection etc...) and few other
things (simple user interface etc...). For more sophisticated ECG signal
analysis you will need more processing power (probably DSP).

I use the Digi XBee modules with the LPC21xx. Simple serial port connection, 3V logic level. I don't need/use ZigBee, just the 802.15.4 protocol in peer to peer mode. ZigBee is *not* a synonym for 8702.15.4, as TCP/IP is not a synonym for 802.3 ethernet.

So it's easy.

I think you are going to buy a XBEE module or other compatible, if yes:
Offcourse LPCs can work with it for ECG, you will need a good sample rate to
get good ECGs, witch lpc have. And you will need memory to group the data to
send it once, witch LPC have as well.

I don't see what is your dilema.

Which data rate do you need worst case ?

Does ZigBee support you worst case data rate ? This will give a first hint

AFAIK any 32bit controller and even 16bit controller can run the ZigBee stack.

Maybe you should read more about ZigBee and check the application notes.

This will surely help you more than posting such generic questions.
