Pathophysiology, diagnosis and treatment of tachycardiomyopathy

Learning objectives

  • Recognise the diagnosis of tachycardiomyopathy (TCMP)

  • Understand the pathophysiology

  • Determine treatment strategies to restore left ventricular function

  • The role of TCMP in non-responders to cardiac resynchronisation

  • Introduction

    Tachycardiomyopathies (TCMP) are an important cause of left ventricular (LV) dysfunction that should be recognised by physicians as they are potentially reversible and have a significant impact on morbidity and prognosis. They are classically defined as the reversible impairment of ventricular function induced by persistent arrhythmia. However, it is becoming increasingly evident that they can be induced by atrial and ventricular ectopy promoting dyssynchrony and indeed the term ‘arrhythmia-induced cardiomyopathy’ is emerging to describe the phenomenon.1 2 A more current proposed definition highlights aetiology: ‘Atrial and/or ventricular dysfunction—secondary to rapid and/or asynchronous/irregular myocardial contraction, partially or completely reversed after treatment of the causative arrhythmia’3 (figure 1).
