This is one important cause of supraventricular tachycardia in Ebstein’s anomaly. Ebstein’s anomaly may present with a murmur for evaluation in the pediatric age group or in adults with arrhythmias or heart failure with cyanosis and exercise intolerance.

so it must be a pediatric ECG. The ECG was done because the heart rate was 230 and the differential included SVT vs. sinus tachycardia. This is typical of pediatric ECGs because the fetal circulation depends on the right ventricle. What can you say about this ECG at a rate of 230 beats per minute?

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

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. During the next 24 hours, she experienced periods of complete AV block with a ventricular escape rhythm in the 20s. She was started on isoprenalin (isoproterenol). The following ECG was recorded during one of these episodes of VT.

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.

Objective Describe the methodology and role of CNA for treatment of pediatric patients with functional AVB or SP. with one documented SP after termination of atrial tachycardia at the 3-month follow-up. Methods This is a single-center, case series study. Post-CNA, the median longest pause was 1.3 s s (range 0.8–2.2)

It is seldom done in pediatric age group. There is a potential risk for drug challenge in that life threatening ventricular arrhythmias could be precipitated. Hence drug challenge is to be done only in a monitored intensive care facility. With proper precautions, risk can be reduced.

Interpretation: There is sinus tachycardia, with right bundle branch block (RBBB). She was pulseless, with a narrow complex tachycardia on the monitor. She was intubated. A FAST exam was normal (no pericardial or peritoneal fluid). As part of her workup, this ECG was recorded: What do you think?

There is sinus tachycardia and also a large R-wave in aVR.

Her temperature was 106 degrees. As part of the workup, she underwent an ECG.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. Pediatric and elderly patients were more predisposed to developing an arrhythmic event in the setting of fever [7]. A rectal temperature was obtained which read 107.9
