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

Does electrode placement on EKG affect outcome results, ?

Does electrode placement on EKG affect outcome results, ?

Ecg: The ECG records the vector direction of the signals in the heart. As such the placement of the leads is crucial to the interpretation of the ECG patterns recorded. ...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

Had an EKG done my doc's office. The medical assistant pressed very hard on my chest (on the sternum&around it)to find the right locations for the electrodes. This hurt my chest a lot/caused bruises/pain/shortness of breath. Can this harm my heart/aorta?

Had an EKG done my doc's office. The medical assistant pressed very hard on my chest (on the sternum&around it)to find the right locations for the electrodes. This hurt my chest a lot/caused bruises/pain/shortness of breath. Can this harm my heart/aorta?

Musculoskeletal.: Your discomfort and shortness of breath are likely musculoskeletal due to the excessive pressure upon the muscles and bones of the chest wall. The MA would not have been able to press deep enough through the chest wall to affect the heart, lungs or aorta directly. But if your symptoms persist more than a few days then you should see the doctor. ...Read more

What are common causes of an abnormal ECG?

ECG: There are a myriad of causes of abnormal ECG tracings. Any cardiac abnormality that is signficant will usually cause some change in the ECG. Changes in blood chemistries can alter the ECG, high blood pressure, heart attack, lung diseases and a long list including things that really don't mean much but change the appearance of the ECG recording... ...Read more

What does rsr' in v1 or v2 mean on an ecg?

What does rsr' in v1 or v2 mean on an ecg?

Likely normal: Rsr', pronounced 'r s r-prime' can be a normal finding in leads v1 and v2. This pattern is often found in young healthy people.
An rsr' with widening of the qrs and characteristic findings in other leads is due to a right bundle branch block. This is when the electrical pathway to the right ventricle is slower than the pathway to the left venricle (typically several milliseconds). ...Read more

What does rsr stand for if in v1 or v2 on ecg?

Right Bundle: It's ekg notation for the shape of the waveform, and it means there's either block or delay in one of the heart's 3 "wires" (they're not really wires) that conduct the electrical impulse to the lower chambers. It does not, generally, mean increased risk of death or problems unless other circumstances are present. ...Read more

Can you tell me in ECG interp. Can someone tell me what ivr is exactly?

Can you tell me in ECG interp. Can someone tell me what ivr is exactly?

IVR?: Do you have that right? It's usually abbreviated "AIVR" and stands for "accelerated idioventricular rhythm." The ventricles have an intrinsic rhythm of about 30-35 that is normally suppressed by supraventricular conduction. If there is AV dissociation, the ventricles can beat at their own rate or IVR. More often, the rate is about a 100 so it's called an "accelerated idioventricular rhythm." ...Read more

My ECG showed right ventr hypert. Why? Hr:79, qrs:104, qt/qtcb:372/430, pr:136, p:88, rr/pp: 748/775, p/qrs/t:30/85/25, qtd:40/46, soklw:1.4mv, nk:11.

Right Vent Hypertrop: There are many cuases for right ventricular hypertrophy. I recommend you to get an echo in order to confirm the diagnosis. Ekg criteria for right ventricular hypertrophy has good specificity but sensitivity is not that good. Hence you need to get an echo to confirm the diagnosis. ...Read more

Would a ECG show myocarditis?

Would a ECG show myocarditis?

Often it does. .: Typically there ARE changes on the electrocardiogram in myocarditis: diffuse T wave inversions and saddle-shaped ST segment elevations. Other common blood tests including C-reactive protein, sed rate, & myocardial damage markers may be positive. The only 100% accurate diagnostic test of myocarditis is a myocardial biopsy--biopsy of the heart lining and muscle done via angiography. ...Read more
