DIY ECG

[@drdbbajpai]

masterpiece idea you have given me . i will try to make some projects for diagnosis of various disease conditions, thanks too

[@pamarthikanakaraja9812]

thank you for great video for interfacing the AD8232 SENSOR

[@robertohernandezsannchez6634]

One question, how can you get such a clean signal without external analog electronics?

[@charliecaiki3289]

Thanks, very useful, with this is possible to capture brain signals, like a alpha EEG signal? for example.

[@jubaerhossain1865]

The processing code doesn't work and shows error. Sir, did you use the same arduino and processing code that sparkfun has supplied or you modified? If you did so, can you give me any direction? I have my project to submit very soon.

[@rebirth3X]

That's great. Do you have any sample code, for in particular the eye movement example you show (at around 6:54 minutes in)? I'd also like to know what electrodes (their colours) go where on the body, as you only appear to have 2 on your head?

[@klausziegler60]

Fascinating

[@belalfaiq6046]

Hello, I need know information, the EMG sensor, can be used to measure the electrical activation for muscle and Show them digitally?

[@alhassanumar4450]

Please, kindly help me with the steps to connect the A8232 kit to Oscilloscope. Thanks for your time.

[@UnrealTransformer]

Connect the Pin that is labeled "output" on the pcb of the kit to the "input" labeled "ch1" of your oscilloscope.

[@Ziplock9000]

5:50 "It is impossible to view on an ordinary oscilloscope". Many scopes that have 2 or more channels have maths functions that effectively make them differential amplifiers. The relatively cheap Rigol ds1054z has 4 channels and it's maybe possible two have 2 differential channels.

[@SilverSpoon_]

Very useful, was just curious how I could monitor my heartbeat with my oscilloscope... I soon will control and hack any computer or electronic device with my mind.

[@govalle3]

Hello i have an issue in the T wave at the heart pulse, it is to big, do you know how can i reduce it ?

[@sheylaromero76]

Hola, el AD8232 puede captar la espiga de un Marcapasos?

[@Nikolaos7427]

ECG or EKG is a synthetic Greek word which consists of tree words.Not german. Electro from electricity [ilectron (amber) is a seed of a plant which obtain positive static charge by attrition on wool and was discovered by Thalis Milisios], cardio from kardia (heart) and gram from gramma (write,letter,graphema etc).

[@rizkotrinanda4084]

awesome, so we can use ad8232 for recording emg signal?

[@Suncatcher173]

Hello. Do you know an easier way to monitor the heart beat of a person with only a "beep" without any patch? Maybe via a smart watch?.

[@TranslatorsCafecom]

An oximeter can show your heartbeat. It will beep and display your pulse rate.

[@Suncatcher173]

@@TranslatorsCafecom hi. Thanks. But i wish to have a device that can be worn permanently to notice the h.beat variation with an acoustic signal

[@santureddy8920]

Hi, I liked this video , its gives more application of AD8232 aside from just ECG. I have purchased the same board and testing the board. I'm facing problem with the output signal which is very noisy. I have connected the board with 3.3V and connected the output to oscilloscope. All I can see is a noisy signal. Can you help me out with this? Thank YOu

[@TranslatorsCafecom]

Hi Santu, I had the same problem at the beginning. Most probably the signal is noisy because of bad contacts between your skin and the electrodes. Another cause of noise is switching power supplies and other electronic equipment. Try to make your experiments in a room without computers and other electronic equipment. Anatoly

[@aunreza]

TranslatorsCafe.com the output i am getting from this sensor is a square wave. I powered it using an Arduino Uno r3 (3.3volts). Could it be that arduino power is not stable enough? The provided electrodes were attached to right wrist(RA), left(LA) wrist and RL to right ankle bone

[@mechatronicsninja3806]

Thank you for your tutorial. I'm working on a similar project measuring the EMG and I have some question: 1- I tried to measure the electro-activity of my hand, I placed the electrode the same as shown in minute 6:34 (the yellow electrode is connected to a bone surface) but I can't get the same results. I have tried this experience several times, but I couldn't have a good signal. 2-the ECG frequency (0.5 Hz to 3 Hz) and the EMG frequency (20 Hz to 3000 Hz), how to modify the AD8232 schematic so that is can measure all the frequencies??

[@Bozza36]

Did you end up working it out?

[@esmirno1]

Есть ли кит с экранированными проводниками для ad8232? стандартные провода с китов на али жутко фонят.

[@Anugreh1]

Hi,I loved the video. I purchased the AD8232 after watching the video. I am trying to make an EMG armband by this boards. I'm facing problem with the signals. They are throwing some random values. When,I close fist fist it shows the right signal but after that it again starts throwing some random values. I have placed the electrodes parallel on my arms. Do I need to change the electrode placement or something else? Please help me out with this? It will be much appreciated.

[@TranslatorsCafecom]

Hi Anugreh, try to make good contacts between your skin and electrodes. Also, try to move your equipment away from computers with switching power supplies and from fluorescent lamps. Don’t forget to put all three electrodes on your body and all three with good contacts with your skin.

[@Anugreh1]

Hey,I did all that. But,Still when I plug in the sensor,The signal doesn't go down from 300. And then,It just starts throwing random values.

[@TranslatorsCafecom]

Unfortunately, in this case i cannot help.

[@steuk6510]

You can use a different ecg board using shield board one

[@thomasbinder4905]

i am again sorry ,more easy . want to use a android phone .... what i need for a chip in front of the red once. and i need a app to check the EKG. or a pogram i have firefox,google, and more on the phone,i have a W-Lan and monitor cip in front of the red once but the monitor chip show me nothing only he say 3,3 volt and it,s 3 WLAN strong in your house.not more help me please a littel bit. byby

[@kamrannt]

Very nice sir👍👍

[@TranslatorsCafecom]

Keep watching

[@RadioactiveBamboo]

how well does the ecg heart rate work while moving around? would i be able to type and move my mouse around while hooked up and still get a good reading?

[@TranslatorsCafecom]

It works, but with noise. Moving or even talking will distort the signal because of electrical activity generated by muscle movement. The signal from muscles can be stronger than the signal from the heart.

[@Rafael-su8pf]

Hi, can you sand me the schedules of how you plug the arduino in thr AD8232? Thanks

[@Rafael-su8pf]

And where you connect theo scilloscope?

[@drdbbajpai]

good information

[@dr.josetorres9554]

Great !!!!

[@alitorabi43141]

Hi, How can one get also the pulse (bpm) from this moduls? Thanks

[@juanvillalobos6899]

hi, i have the same question. i need to know the pulse from the ecg module

[@ananthaprasetya3263]

u need count signal period. using millis on arduino.. its internal counter

[@alitorabi43141]

Thanks for your reply. I am familiar with 'millis', but the questions is really how to count/determine signal period. should it be peak to peak, for example? Or it be simple detected from reading one of the pins on the chip?

[@ananthaprasetya3263]

u can count period peak to peak or R to R,, i'm using lead 1. or other method is count peak for 10s then multiple with 6..

[@hrithikparihar6073]

What is the source code for emg

[@AvinashGhatge]

The values which we get on the serial monitor of Arduino IDE which are as follows: 320,322,333,340,320,..........etc what are these values.... are these voltages or what?

[@StolenFusion]

Yes.

[@flavialopes5354]

Hi, Avinash. I know it's been a while since you wrote this but i'm having the same readings and i have no idea of what to do. Did you solve it?

[@ahmedrifat1099]

Actually, these are digital values. These need to be converted to voltage values based on your Analog to Digital Converters resolution.

[@ahmedrifat1099]

@@flavialopes5354 I think these are digital values. These need to be converted to voltage values based on your Analog to Digital Converters resolution.

[@thomaslapsley8145]

The videos good but, you look like big brother on the cover picture with that stare. The pictures of you in the video are different and nice. Intimidation never wins with a picture. I don't know what your target audience or purpose is from the front picture. I really like everything else, the video does look very professional, really good job. Your knowledge of basic ECG / EKG is good and electrical engineering is good. I wish you went into a little more depth on possibility a differential op amp used to reduce the noise of the displayed ECG / EKG.

[@TranslatorsCafecom]

Hi Thomas. Thank you for your comment. I thought the cover picture resembles those in the video :). It was added on the cover just to show who is speaking. Please consider that my primary job is running TranslatorsCafe.com and these videos are just an attempt to tell people about the Unit Converter www.translatorscafe.com/unit-converter/en/charge/, which is the main part of the website.

[@thomaslapsley8145]

Thanks for the reply. It's the style of the picture I was trying to help their are different communities. I was trying to help the noise is the problem with the sparkfun and I need the precordial leads but, it's great to get people involved in biomedical engineering. I'm studying cardiology I was looking for a 12 lead system an found your video. I'm having problems because some group put something in the Wholefoods etc... red cap water gallon of distilled water that's cause high blood pressure and now a different auscultation in my heart. Be careful a lot of sick gangs in NYC with sick doctors. Good luck.

[@thomasbinder4905]

sorry .!!!!! but where i can see how i go into the computer . i think, i must buy a spez. chip in front of this red chip. and i think i need a pogram . when you tell me what i need, than i buy it. but so, i never get x/y wave. help me please ,a pogram link, and the chip in front of the red chip. and than to the computer . i like android phone's. is it more easy whith the phone i think. gif me please a link to buy the cip in front,for a android phone. when you have a link.i need more information,so mutch !!! it never run whithout a cip in front of it . sorry for my scool englisch, it is 45 j. a go. how i lean it. and my translator, i don,t like him. thank,s and have a nice day.
