Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

What arrhythmias can be identified with a ECG signal taken using la, RA and ll electrodes?

What arrhythmias can be identified with a ECG signal taken using la, RA and ll electrodes?

All of them: There are no la and RA "leads" on a standard ekg, so i'm interpreting your question as "what can you find with just 4 wires?" the answer is "just about anything." with those 4 leads, i'll have 6 printouts of your heart, good enough to diagnose all types of rhythm problems. I may need the other 6 wires to better classify them, and determine where the rhythm problem is specifically though. ...Read more

Where do I place an EKG electrode on a woman with no breasts or a bilateral implant?

Not a problem: The electrodes are not placed on the breast in anyone so it's not an issue. V1 goes to the right of the sternum; v2 (left 2nd ics) v4 in the mid-clavicular line 5th ics; v3 between v2 and v4. V5 in the anterior axiallary line 5th ICS and v6 in the mid-axillary line 5th ICS - none go on the breast which would act as an insulator and interfere with the tracing. Ics=intercostal space. ...Read more

Can i be allergic to EKG electrode patches? I had an EKG yesterday, and this morning I have an itchy red rash in all the spots where the patches were. Could it be an allergic reaction? It itches a lot. Could it be serious?

Can i be allergic to EKG electrode patches? I had an EKG yesterday, and this morning I have an itchy red rash in all the spots where the patches were. Could it be an allergic reaction? It itches a lot. Could it be serious?

Yes. : Yes. This sounds like an allergic reaction to the adhesive or latex in the ekg electrode patch. Many people are sensitive to adhesives. Be sure to tell your health care provider to add this to your list of allergies. Also, let your health care provider know about your rash/itchy reaction so he/she can recommend treatment. (usually an over the counter cream). ...Read more
