male with pertinent past medical history including Atrial fibrillation, atrialflutter, cardiomyopathy, Pulmonary Embolism, and hypertension presented to the Emergency Department via ambulance for respiratory distress and tachycardia. Description : Regular Wide Complex Tachycardia at a rate of about 160.
Wild-type transthyretin amyloid cardiomyopathy (ATTRwt-CM) is often accompanied by atrial fibrillation (AF), atrialflutter (AFL), and atrialtachycardia (AT), which are difficult to control because beta-blockers and antiarrhythmic drugs can worsen heart failure (HF).
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 atrialflutter (AFL) and the effectiveness and low risk of catheter ablation of AFL.
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.

In all probability, this dilation is a form of atrialtachycardia and atrialcardiomyopathy. However, underlying lesions such as hypertension, mitral valve disease, COPD, ASD, and TR greatly influence the degree of atrial enlargement. We know atrialflutters can be confined to one atrium.
They had a history of non-ischemic cardiomyopathy (EF 30%), as well as PCI with one stent. Initial ECG in the ED: Presenting ECG : Wide-complex tachycardia at a rate about 200. This is overwhelmingly likely to be ventricular tachycardia, even if only age and medical history are considered.
She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. The ECG was interpreted as showing atrialflutter with 2:1 conduction. Answer : The ECG above shows a regular wide complex tachycardia. The heart rate could be compatible with that of a 2:1 conducted atrialflutter.
Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology. Read about Fascicular VT here: Idiopathic Ventricular Tachycardias for the EM Physician Case Continued He was completely stable, so adenosine was administered. See Learning point 1 below. Arch Intern Med.
Here was his ED ECG: There is sinus tachycardia (rate about 114) with nonspecific ST-T abnormalities. There is a large peaked P-wave in lead II (right atrial enlargement) There is left axis deviation consistent with left anterior fascicular block. The absence of any wall motion abnormality makes ischemic cardiomyopathy very unlikely.
PurposeAtrial tachycardia is an uncommon supraventricular tachycardia in children. It is often drug-resistant and likely to occur concomitantly with tachycardia-induced cardiomyopathy, making radiofrequency catheter ablation the preferred treatment. A total of 78.6% No postoperative complications occurred in any patient.
Whenever I see PVCs with the morphology and axis seen in todays case I always look for signs of AC ( Arrhythmogenic Cardiomyopathy ). Arrhythmogenic cardiomyopathy often manifests with PVCs from the RV. The ECG in Figure-1 however, shows no signs of arrhythmogenic cardiomyopathy.
