Question 1

if left arm and right arm ecg leads are put on the shoulders instead of the wrists can this effect the qt/qtc reading?

Accepted Answer

No: It makes no difference.

Question 2

what does baseline wander in leads v3, v4 mean on ecg?

Accepted Answer

ECG : Baseline wander is a non cardiac signal problem in recording the ecg.

Question 3

t wave amplitude has increased in anterior leads- is this normal? this was not on my ecg from 1 year ago?

Accepted Answer

Anterior dads EKG: The height of the waves is very sensitive to placement of the leads on your chest. It is best to have each EKG done by the same machine and same person.  Discuss with your Dr.  So may be an artifact.

Question 4

is it bad if the p and the r wave are the same amplitude and shape on all leads from an ecg and what does this mean. amplitude for both was 3.5 mm.

Accepted Answer

Redo EKG: It's not  possible for a properly done EKG to have the P and R waves identical in amplitude in ALL leads.   Redo the EKG.

Question 5

what does nonspecific t abnormalities on lateral leads mean on an ecg?

Accepted Answer

T abnormalities: As the description says, they are non specific and do not cause alarm by themselves and need to be correlated with clinical symptoms.

Question 6

i know that standard ecg has 12 leads, but sometimes on some ecg i see additional strip. what is this is there a 13th lead? could you pls explain

Accepted Answer

The usual format for: a 12 lead EKG includes a lead II rhythm strip across the bottom of the tracing. That is the strip you are referring to. It is just a continuous lead II not a "13th" lead.

Question 7

when you get a 3 lead holter 24hr ecg what lead/leads does it record? lead ii?

Accepted Answer

Usually: CHEST leads.....Leads V1 and V2  AND V6

Hope this is helpful

Question 8

very slight st elevation in leads v4-v6 on ecg. all else normal... is this an mi?

Accepted Answer

Ecg: Very slight ST elevation is likely nothing to be concerned about in and of itself. The waves on an ecg need to be interpreted in light of clinical situations as there are multiple possible reasons for most variations from absolutely normal on these tracings. In a 19y/o minimal ST elevation is highly unlikely to represent an MI unless associated with specific symptoms.

Question 9

i had an ecg done. borderline low voltage in frontal leads. borderline st elevation anterolateral leads means?

Accepted Answer

EKG: Ekg by itself doesn't mean anything. It has to be matched with the clinical picture. For example hear attack symptoms with st elevation can be active  heart attack.  Minimal st elevation  without any symptoms could be something called j point elevation. Low voltage  most of the time are normal but rarely could be seen in  fluid around the heart.

Question 10

the p wave on my ecg was pointed including on leads v1 and 2. the amplitude was 2 mm. what are the possible causes?

Accepted Answer

Normal: This sounds like a normal finding.
