Key result
Arrhythmia-induced cardiomyopathy is a reversible cause of ventricular dysfunction that can result from tachycardia, premature ventricular complexes, and atrial fibrillation.
Why the study?
Premature ventricular complexes and atrial fibrillation can result in ventricular dysfunction without rapid ventricular rates, broadening the concept of arrhythmia-induced cardiomyopathy.
This review outlines the current understanding, diagnosis, and management of arrhythmia-induced cardiomyopathy, highlighting that premature ventricular complexes and atrial fibrillation can cause ventricular dysfunction even without rapid rates.
May prompt evaluation for reversible arrhythmia causes in unexplained LV dysfunction; leaves open optimal management strategies for prospective trials.
Tachycardia is one of the important reversible causes of ventricular dysfunction. More recently, it has been recognized that premature ventricular complexes and atrial fibrillation can result in or contribute to ventricular dysfunction in the absence of a rapid ventricular rate. The term arrhythmia-induced cardiomyopathy was introduced to include all these potential causes. In this review, we will discuss our understanding of AiCMP and current best practices for its diagnosis and management.
