G‧N‧M

有點小 tricky，但不會太複雜的心電圖。

SR 60 bpm with 1st degree AVB, NSSTTC

Also

‧ Right axis deviation

‧ Positive QRS complexes in aVR

‧ Poor R-wave progression in precordial leads

more dextrocardia ECG features

‧ Lead I : inversion all complexes, aka "global negative"

(not seen in this ECG, I guess the T waves inverted cause this)

First thing is to check the arm leads, if they are in right position,

the PRWP in precordial leads, the positive QRS complexes in aVR and right axis deciation,

remind that the vector is rightward.

You can predict what the CXR will be like a right heart.

This patient's CXR :

And following right side ECG :

The R-wave progression is showed up in precordial leads.

Ps. PRWP in precordial leads is often seen in ECG,

more often, they come in reasons.
