The presence of symptoms mimicking pacemaker syndrome in the absence of a cardiac pacemaker.

  Extremely long PR intervals (
>300 milliseconds) (1st degree AV block) is the cause.

Lack of synchronization between atrial and ventricular contractions is the cause of this syndrome.

Symptoms of (Pseudo)-Pacemaker syndrome:


  Pulsations in neck, abdomen

  Malaise, fatigue

  Chest pain or fullness

  Headache, jaw pain

  Dyspnoea on exertion
