Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrial flutter (AFL), and atrial tachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).

Introduction Danon disease is an X-linked disorder caused by pathogenic variants in lysosome-associated membrane protein 2 ( LAMP2 ) gene, typically characterized by the triad of hypertrophic cardiomyopathy, myopathy, and intellectual disability. However, many patients may not present the typical presentation, especially in the early stage.

They had a history of non-ischemic cardiomyopathy (EF 30%), as well as PCI with one stent. The WCT is interrupted by a series of variable-morphology QRS complexes, with atrial flutter waves note in II, III, and aVF. The subsequent EP study could not induce VT, only atrial fibrillation.

The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely. There is atrial activity before every QRS, but that activity has negative polarity, so it is not sinus rhythm. The new onset cardiomyopathy was thought to be due to both drug/alcohol use and to Tachycardia-Induced Cardiomyopathy.

Cheng and Zhang to our paper1, we note that despite ARVC being a relatively uncommon cardiomyopathy, we uniquely report on a large clinical experience with very long-term follow-up after VT ablation and confirm a high incidence of atrial flutter (AFL) and the effectiveness and low risk of catheter ablation of AFL.

In all probability, this dilation is a form of atrial tachycardia and atrial cardiomyopathy. However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. We know atrial flutters can be confined to one atrium.

So this is an extremely slow atrial flutter with 2:1 conduction. Atrial rate 146, ventricular rate 73. I suspect that the amyloid slows the conduction of the atrial flutter. It turned out that he had a history of slow atrial flutter. The chart revealed that the arrhythmia was not new.
