Welcome to another weekly case on ECGclass. :)
If you are new to either @ECGclass, #ECGclass, or this blog - please click here to find out what it's all about!
ECG class is delighted to welcome our second guest speaker of the term!
A big welcome to Simon Ross Deveau.
Simon can be found on Twitter @sydeveau or via his ECG blog: Bits and Pieces from an ED Nurse
As an ED nurse, Simon has come across a variety of ECG problems in the ED.
Problems range from ED staff doing them wrong, ambulance crews querying ischaemia/ST deviation, and people being referred in with abnormal ECGs, who go on to have normal ECGs when electrodes and leads are positioned correctly.
So this weeks ECG class looks at a case of mistaken identity.

What happens when ECGs are done wrong?
Thank you Simon! :)
Here goes, and have fun…..…

Q1 What is the correct electrode position of the precordial leads?
Correct precordial lead positioning:
V1 L sternal border, 4th intercostal space. V2 R sternal border, 4th intercostal space
V4 Midclavicular line, 5th intercostal space.
V5 Anterioraxillary line
V6 Midaxillary line
V3 Midway between V2 & 4.
-------
Q2: What technical error does the ECG below show?
Lead I is –ve and aVR is +ve = general R direction of cardiac impulse.
The differential diagnosis here would be right sided heart (dextrocardia/dextroposition).
---------
This ECG shows reversal of V1-V6.
Note the RS progression in reverse.
--------
Q4: Are we worried about this ECG?
