Presentation
Unwell, fever, breathlessness, advanced HIV, very low CD4
Patient Data
Mobile AP erect resuscitation image.
Multiple ECG electrodes representing the V1-V6 chest leads, annotated on the second image.
Bilateral patchy ground glass opacity of the mid and lower zones with relative peripheral sparing in an HIV patient with very low CD4 represents PCP.
Case Discussion
Chest lead skin positions 1:
V1: 4th intercostal space, right parasternal
V2: 4th intercostal space, left parasternal
V3: midway between V2 and V4
V4: 5th intercostal space in the nipple line in men (under the breast in women)
V5: midway between V4 and V6
V6: midaxillary line on the same horizontal line as V4 (may not be 5th intercostal space)
Remember that the CXR appearance will appear to differ from the above as these are the positions on the skin.
