AV Nodal Re-Entrant Tachycardia: Diagnostic Tests

Obligatory medical device diagnostics.

  • Electrocardiogram (ECG; recording of the electrical activity of the heart muscle) – indicates the conduction of excitation of the heart [typical AVNRT: regular narrow complex tachycardia that can reach frequencies > 200/min; in sinus rhythm, the ECG usually shows an unremarkable picture].

Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics and obligatory medical device diagnostics – for differential diagnostic clarification.
