Hi everybody 

Iam 50+ cardiologist. When I was few decades younger. I used to disassemble whatever I get my hands on. That stopped with the demands and pressure of the profession. Recently I incountered arduino, and i was fascinated by the board. I had many things in my mind. Iam planning to use the board to record the electronic activities from the heart by surface mapping using multiple electrods. Collecting the signals and send it to another platform for analysis. Also I want to develp a system for beat to beat blood pressure measurement I think arduino has few analog inputs and somewhat slow. What do you think and what other boards can do the job?

@hisham343

But don't you have state of the art cardiological equipment at your clinic?

Sure I do but sometimes you want to do things that the engineers didn't include in this equipment. Other cause that I want to know how these machines are made and how to develop them the way you want as an end user.

Let us know how it goes and if we can help. Good luck 🙂

Will be interested in your progress.  There are some people here that have coding experience.

@robotbuilder He might also want to check out what Apple is doing with 'just' a watch.

The problem is, not all ptients whom in need for recording their EKG can afford an Apple watch. I am thinking of a very economic solution. By recording one to six leads by a small battery powered device and send the recording to a mobile phone via Bluetooth. And then the patient will send this EKG to me. This device is already in the market but still expensive.

@hisham343 I wasn't suggesting they buy an Apple watch, just use it as a model of what is possible without sticky leads. Of course if you wil have sticky leads then it is far less portable but 6 leads is a lot better than Apples one. What country are you making this for?

@hisham343 Hi hisham. Do you have some write up of what you want your program to do? Like "measure heart beat for 3 minutes and send the data to a website?" or " measure blood pressure and turn on a red light if it is above 90 and turn on a green light if is is below?"

Have you used an arduino to do anthing yet? Have you used the hobbyist sensors that are common like the movement sensor, or the distance sensor?

I have seen this project. I think its too complicated for a very simple already available device in very affordable price. What this project really need is to upgrade this device to a beat by beat blood pressure measuring device using the pulse arrival time as a principle. And I am planning to experiment with this principle and make the device for clinical use in patients with nurocardiogenic syncope undergoing head up tilt table test.

Actually the available devices just use a stainless steel plates to get contact with the patients right and left index fingers (without the sticky stuff) and they use an additional electrode which contact the patients left thigh. To constrcuct a 6 lead EKG.

But not available or affordable here in Egypt.

@hisham343 Yes, but Apple watch (I have one) does it with only the back of the watch and some lights so there are some even easier ways to do it.

I think for apple watch demand that you touch the knob with the right index finger while wearing the watch on left wrist. That means it records the potentials between the knob and whatever touching your left wrist. Its the same principle but in an elegant way 😀
