Abstract
Tachycardia-induced cardiomyopathy appears to be a possibly not very rare clinical event, characterised by a reversible disorder of the systolic function of the ventricles with signs of cardiac failure based on chronic or even intermittent tachyarrythmia. In the therapeutic approach, a key role is played, alongside the treatment of cardiac failure, by the normalisation, or at least adequate control of cardiac rhythm, preferably by non-pharmacological treatment, which leads to restoration of the systolic function of the ventricles, generally within weeks.
