Question 1

can incorrect lead placement lead to an inverted t-wave on ekg?

Accepted Answer

Yes: Yes, absolutely.  Avr usually has inverted t-waves normally.  If you invert left and right arm electrodes, avr becomes avl so now avl has inverted t waves (where as typically it does not).

Question 2

lead placement for a five-lead ecg system ?

Accepted Answer

Standard: Most typical 5 leads are: right arm, left arm, right leg, left leg, v1 lead.
For convenience, they are usually put on the torso.
Put the arm leads by the corresponding clavicle.
Put the leg leads at the inferior edge of ribs on each side.
Put the v1 lead just to the right of the sternal border at the 4th intercostal space.

Question 3

what is the meaning of abnormal ecg and unconfirmed diagnosis and 12 lead, standard placement?

Accepted Answer

: The jumbled words cited have little meaning beyond the obvious and must be interpreted by the doc who ordered the test and knows the history. Abnormal means just that, it does not say why or how much. Unconfirmed = unconfirmed. 12 leads are the standard for many people who do EKG's &amp; includes leads on the extremities and the chest near the heart.

12 leads standard placement?

Accepted Answer

No definitive pathol: Most likely represents LVH which is thickened heart muscle. Had to say without seeing EKG. If concerned repeat EKG or get echocardiogram.

Question 5

66 year old female here.had ekg which showed lvbb - however the tech had me leave clothing on and put leads on belly and hips not legs and just below neck. was this wrong placement. echo one year ago normal. ekg normal apr now advised to repeat echo?

Accepted Answer

: I'm assuming you meant LBBB (left bundle branch block).  The EKG, performed with abnormal lead placement might have accurately displayed an abnormality suggestive of a left bundle branch block, it should be confirmed with a repeat EKG with leads properly placed.  Concerning an echocardiogram, a repeat should be based upon one's history, physical exam and any pertinent tests performed.

Question 6

is a 10 lead ekg machine as good as a 12 lead machine?

Accepted Answer

Depends: In some cases, a 3 or 5-lead ekg provides sufficient information. However, for a full picture of what the heart is doing, a 12-lead is the best.  It takes 10 physical leads to produce a 12- lead ecg. Left and right arms, left and right legs, v1-v6.

Question 7

what should p waves look like in lead v1? what does it mean if different on some ekg?one will show completely positive,one fully negative,another biph

Accepted Answer

There can be a lot: of normal variability to the p-wave morphology in V1. More so in women. In general a biphasic or mostly upright p wave is usual. Certainly you could have an ectopic atrial activation in which case the morphology would be altered. Physical positioning (sitting, lying or at 30 degrees) for the EKG will also make a difference. Lead position too. Regardless it is usually of no clinical significance.

Question 8

i had my first ten lead ekg yesterday. machine says old anteroseptal mi. 52 year old female. no history. neg family history. thoughts?

Accepted Answer

ECG: the ECG like most tests has false positives. Discuss with your doc, if indicated additional workup is possible

Question 9

hi my ecg shows low voltages precodial lead and abnormal ekg means what?

Accepted Answer

: There is not enough information for a correct response. You should discuss with the doctor who ordered the EKG. Otherwise, you need to give more info such as the reason for EKG, your medical history and the complete electronic EKG reading. If the only abnormal finding on EKG is low voltages on precordial leads, I doubt of any serious issue.

Question 10

if i had hyperkalemia wouldn't it show peaked t waves throughout entire 12 lead ekg with widened qrs?

Accepted Answer

Depends: That is with life threatening hyperkalemia.  If your case is mild, or chronic, it may not manifest yet with ekg abnormalities.
