    “…OBJECTIVE: The aim of this study is to present electrophysiologic characteristics and catheter ablation results of tachycardia-induced cardiomyopathy (TIC) in children with structurally normal heart. METHODS: We performed a single-center retrospective review of all pediatric patients with TIC, who underwent an electrophysiology study and ablation procedure in our clinic between November 2013 and January 2019. …”

    “…BACKGROUND: The present study investigated the safety and efficacy of mapping and ablating isolated premature atrial contractions (PACs) in patients with a structurally normal heart, as well as whether the elimination of PACs by radiofrequency catheter ablation (RFCA) improved symptoms and the quality of life. …”

    “…We found that the uPWR‐integral overestimated compared to the ttPWR‐integral by about 10% (P < 0.001) in both normal hearts and during ventricular dysfunction. Bland–Altman limits of agreement were at +0.060 and −0.054 J, without increasing spread over the range. …”

    “…BACKGROUND: We examined risk factors for development of ventricular tachycardia (VT) in pediatric patients with ventricular premature contractions (VPCs) and a structurally normal heart. METHODS: The subjects were 81 844 first graders and 88 244 seventh graders of Kagoshima City School‐based cardiovascular screening (SCV‐screening) between 2001 and 2015. …”

    “…The predictive value of non-invasive electrocardiographic examination findings for the risk of sudden cardiac death (SCD) in populations with structurally normal hearts remains unclear. This study aimed to investigate the characteristics of the QRS vectorcardiography of surface electrocardiography in patients with structurally normal hearts who experienced SCD. …”

    “…We aimed to use STE for early detection of LV dysfunction in patients with apparently normal hearts who have frequent VESs. METHODS: Fifty-five patients with frequent VESs were identified according to the Lown classification (Grade 2; unifocal more than 30 times in 1 h). …”

    “…BACKGROUND: This randomized study was aimed to compare the diagnostic value of two head-up tilt testing protocols using sublingual nitroglycerin for provocation in patients with recurrent unexplained syncope and normal heart. METHODS: The patients with normal findings in physical examination, electrocardiography and echocardiography were randomly submitted to one of upright tilt test protocols. …”
