Expert ECG 5
- Normal sinus rhythm
- Premature atrial contractions
- Right axis deviation
The ECG findings of dextrocardia include a predominantly negative P wave (when sinus rhythm is present), negative QRS complex, and negative T wave in lead I. This results in a rightward QRS axis. There will also be low voltage in leads V3-V6 since these leads are placed on the left side of the chest and no heart is present at that location. The dextrocardia ECG findings can appear similar to limb lead reversal in lead I, however if the limb leads are simply misplaced, leads V3-V6 will appear normal and not low in voltage as seen in dextrocardia.
