Try again:

Dextrocardia , possibility with Kartagener's syndrome.

1: small circular, erythema, non-elevated lesion around the right nipple at 3,5,7 o'clock at position where chest leads would be if it was at left chest

2: right axis deviation and loss of voltage across the precordium. There are also inverted p waves in leads I and aVL

1. dextrocardia
2. temporary erythema due to suction (unlikely sensitivity to gel/lead as only 3 reddish mark instead of 6.

2nd question:
how will u proceed, darren?

Darren Lee said...

Ha ya this is actually a very straightforward one:

Pic is showing electrode leads mark - but of a right-sided one. If you get such case in exam, you already know that it's dextrocardia before you examine. The other circumstance that we do right-sided ECG is to look for RV infarct in Inferior MI - unlikely to come out in exam.

ECG shows what we called "Reverse R progression" - a feature of Dextrocardia.

Then you should proceed to palpate for side of liver - look for situs inversus, and auscultate the lung bases for crepitation - bronchiectasis in Kartagener's syndrome.
