Genetic diagnosis is becoming increasingly important in guiding the management of children with inherited cardiac arrhythmia syndromes. Ultra-rapid genome sequencing (average turnaround time of three days) has been available in our centre since March 2018 and has the potential to improve and refine management of this group of patients.

Cardiac manifestations of laminopathies include atrial and ventricular arrhythmias, atrioventricular (AV) conduction disorders, and cardiomyopathy, with or without skeletal muscle involvement. Due to its rarity and previous cardiac characterization as adult-onset, pediatric data is limited.

Additionally, changes in ionized calcium levels positively correlated with QTc changes in DKA.Conclusion:While the Bazett formula often overcorrects QTc in pediatric DKA, a true QTc interval increase does occur during DKA, albeit less significantly than previously believed. The Rautaharju formula provides a more accurate correction.

Abstract Introduction Supraventricular tachycardia (SVT) is a common pediatric arrhythmia. We describe the prescriptive tendencies, efficacy, and tolerability of BBs and CCBs used in the treatment of pediatric SVT. Methods and Results This is a multicenter retrospective cohort study from three academic children's hospitals.

Left cardiac sympathetic denervation (LSCD) is an effective treatment for channelopathies, especially in those where adrenaline acts as a trigger for life-threatening arrhythmias, such as long QT syndrome (LQTS) and catecholaminergic polymorphic ventricular tachycardia (CPVT).

However, children can present with potentially lethal arrhythmias at a young age. Although the initial report of Brugada syndrome (BrS) in 1992 included 3 children, subsequent research focused on adults. A better understanding of the factors that trigger an early severe expression of disease is needed.

This can be a source of cardiac arrhythmia as well. An important cause of arrhythmias in Ebstein’s anomaly is the presence of a right sided accessory atrioventricular pathway or WPW syndrome. A huge right atrium can also predispose to supraventricular arrhythmias in Ebstein’s anomaly.

VT is the second most common presenting arrhythmia. Vaso or inotropic medications are not harmless, and can precipitate life threatening arrhythmias. It is common with 2nd- and 3rd-degree AV block to see a " ventriculophasic " sinus arrhythmia. AV block is the first manifestation of CS in more than 30% of patients.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.

As regards AVNRT in CHD patients, it represents the third most common form of arrhythmia in children with CHD.
