AI Article Synopsis
- Tachycardia-induced cardiomyopathy (TIC) is a type of heart failure caused by fast heart rhythms that impair heart function.
- A case of a 16-year-old boy highlights how TIC was misdiagnosed as sinus tachycardia linked to dilated cardiomyopathy, emphasizing the need for accurate diagnosis.
- His heart function fully recovered after radiofrequency catheter ablation, demonstrating the critical role of a 12-lead ECG in diagnosing and managing TIC.
Article Abstract
Tachycardia-induced cardiomyopathy (TIC) is a well recognized entity of heart failure (HF) and various mechanisms due to tachyarrhythmias have been postulated to be responsible for impaired cardiac contractility. Previously reported cases showed reversibility of such disorders whenever stable cardiac rhythm is maintained adequately and we report on a 16-year-old boy who has been diagnosed to have TIC, which was misinterpreted initially as sinus tachycardia secondary to dilated cardiomyopathy and heart failure. A complete recovery of his left ventricular function was achieved by radiofrequency catheter ablation and highlights the importance of a 12-lead electrocardiogram (ECG) assessment in such patients.

Unlabelled: Atrial fibrillation (AF) is a prevalent and clinically significant cardiac arrhythmia, with a growing incidence. The primary objectives in AF management are symptom relief, stroke risk reduction, and prevention of tachycardia-induced cardiomyopathy. Two key strategies for rhythm control include antiarrhythmic drug therapy and pulmonary vein isolation (PVI), with PVI being recommended for selected patients.

Aims: No study has analyzed the impact of guideline-directed medical therapy in preventing heart failure (HF) relapse in patients with arrhythmia-induced cardiomyopathy (AiCM) following left ventricular ejection fraction (LVEF) improvement.
Methods And Results: We analyzed data from a single-center cohort of 200 patients admitted for HF, LVEF <50% and cardiac arrhythmia considered by cardiologists to be the precipitating cause of the episode. The primary endpoint was time-to-HF relapse, defined as the composite of readmission for HF, Emergency Department (ED) visit for HF, or significant decline in LVEF.

Purpose: Atrial 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. The aim of this study was to assess the feasibility, safety, and effectiveness of radiofrequency catheter ablation for the treatment of different types of atrial tachycardia in children, particularly in those with drug-resistant and tachycardia-induced cardiomyopathy.

This case report discusses the diagnosis and management of a 25-year-old pregnant patient presenting with persistent tachycardia. The patient, with a past medical history of thyroiditis, polycystic ovarian syndrome, and obesity, was admitted due to palpitations and was diagnosed with atrial tachycardia. Despite medical management with metoprolol, adenosine, digoxin, and flecainide, the tachycardia persisted, necessitating discussion about cardiac ablation.
