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. This is one important cause of supraventricular tachycardia in Ebstein’s anomaly.

Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology.

IF this was 2:1 AV block — then the P-P interval should be everywhere the same ( with only occasional exception of some atrial tachycardias in adults that may not always be completely regular ). It is important to remember that pediatric tracings manifest a number of differences from adult ECGs.

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. VT is the second most common presenting arrhythmia. Vaso or inotropic medications are not harmless, and can precipitate life threatening arrhythmias. She was started on isoprenalin (isoproterenol).

This is the proposed mechanism of precipitation of arrhythmias in Brugada syndrome during febrile episodes. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. It is seldom done in pediatric age group. This leads to shortening of action potential duration.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. There was a 0.9% Circulation, 117, 1890–1893. [3]:

Atrioventricular nodal reentrant tachycardia (AVNRT) is a common supraventricular tachycardia in children and congenital heart disease (CHD) patients. As regards AVNRT in CHD patients, it represents the third most common form of arrhythmia in children with CHD.

There is sinus tachycardia and also a large R-wave in aVR. Drug toxicity , especially diphenhydramine , which has sodium channel blocking effects, and also anticholinergic effects which may result in sinus tachycardia, hyperthermia, delirium, and dry skin.
