ECG Case 1 – Interpretation

  • Post category:ECGs

Small, negative, regular P waves are present, indicating an ectopic low atrial pacemaker at 60/minute.

They are in competition with and accelerated junctional focus whose rate is 75/minute.

The result is AV dissociation due to usurping junctional pacemaker.

The four capture beats -(C)- indicate that the AV bride is intact.

There is also Right Axis Deviation probably due to Left Posterior Fascicular Block (LPFB).
