How many electrodes in a 12 lead ecg

There are two options. A You can sedate the person to diminish the shaking. B If the shaking is not severe, you can have a few people physically put their hands on the electrodes and hold down firmly which will help lessen the artifact. Since the leads generally go on the left side of the chest, I suppose it could be slightly easier to stand on the left side to prevent reaching across the patient.

I really like your review and commentary. I have worked in an ekg department for 16 years and very often find leads for V1 and V2 near the clavicle, or any place in between. Because, in our hospital, I find such variations in quality of placement, as well as quality of tracing, and there is no one taking charge. As you know, when a patient is in the middle of a code or stat situation, it is hard enough to get to a patient, let alone, follow normal procedure.

So I have learned, if I need to, to do an ekg, by sight. Experience helps. But there are times, I am asked to do an ekg, while the patient is upright, or laying on either side, or shaking so hard, it is almost impossible to get a decent tracing.

So what I usually do, is just get the best tracing I can and relate the change of position, to the reading doctor and make note on the ekg. It frustrates me to occasionally have a less than clear ekg. These are the times I find myself asking questions, but cannot really get any clear answers.

So I will investigate your web site and see, if I can pass on what I learn to my supervisor. Thanks again, for a great intro. Jack, you draw out a good point. Medicine can often be related to working in less than ideal conditions. Experience does help with efficiency, though. Thanks for the input. I was at my physicians office upset due to misdiagnosis and lack of empathy and ability to listen to me, I bacame very upset and I spoke to Manager for about an hour then as I was going to leave I didnt feel well my chest was ice cold my left arm tprwards the back shoukder hurt I explain this to them as I first arrived to office blood pressure was high after the discussion of dr not listening it was extremley higher they offered oxygen and I said I had horrible headache and that most likely call an ambulance doctor came in a few seconds and poped a pill in my mouth I dont know what it was all I remember is it me e my mouth very dry and I hurt and was stiff all over.

Dr called ambulance and didnt tell them she had given me any pill then paramedics placed the leads incorrecly after correcting this only a few short minutes they were done. They said nothing to me and I was unable to drive I left my car at dr parking lot. Many hours later dr calls to tell me the hospital told her that it was inaccurate results because I was moving. I couldnt move and I was given oxygen while this test is being done.

They were the ones who continued to laugh joke around and keep talking. Hi there. I am cardiac RN that works with nuclear stress testing.

During the stress portion, the patient is connected to a 12 lead EKG monitoring system and an EKG is printed every minute of the 4 minute test.

The result is dependent on the imaging from the Spect-CT camera read by the radiologists in our hospital and the cardiologists dictate the 4 minute injection portion we use regadenoson. My question is, how critical is lead placement? Again, the patient is discharged and or diagnosed dependent on the imaging portion, not the EKG tracings. For example, the cardiologist may not even dictate for weeks after the patient is discharged.

Thank you for taking the time to read this and answer, Its a long one. Hi Cindy. Good questions. If you happen to place a lead over a rib vs the intercostal space, that can affect what you see.

Hope that helps. Most people do put it on the rib directly between V2 and V4. I would recommend putting V3 on the 5th intercostal centered between V2 and V4. That should more than sufficiently capture the anterior part of the heart. The other day I had to make an EKG to a patient in prone severe respiratory distress. How would you place the leads from V1 to V6? Thank you. The answer is that it depends. A 3-Lead ECG uses 3 electrodes that are labeled white, black, and red.

These colors are not universal as two coloring standards exist for the ECG discussed below. These 3 leads monitor rhythm monitoring but doesn't reveal sufficient information on ST elevation activity.

A 5-Lead ECG uses 4 limb leads and 1 chest lead. ECG Strip Ease. Covidien Nellcor. Masimo SpO2. Philips EKG. Toco Transducers and Cables. If you need any help with your order, we're just a phone call away.

Women may often wear a bra, T-shirt, or gown. Although it is called a lead ECG, it uses only 10 electrodes. Certain electrodes are part of two pairs and thus provide two leads. Electrodes typically are self-adhesive pads with a conducting gel in the centre. The electrodes snap onto the cables connected to the electrocardiograph or heart monitor.
