Pediatric Exercise Testing

All About Cardiovascular System and Disorders

Discussion on pediatric exercise testing. Pediatric exercise testing may be used for evaluation of various disorders of cardiac rhythm rather than for inducible ischemia as in adults. Bidirectional ventricular tachycardia is the classical arrhythmia noted in catecholaminergic polymorphic ventricular tachycardia.

Young Man with a Heart Rate of 257. What is it and how to manage?

Dr. Smith's ECG Blog

Here is his 12-lead: There is a wide complex tachycardia with a rate of 257, with RBBB and LPFB (right axis deviation) morphology. Read about Fascicular VT here: Idiopathic Ventricular Tachycardias for the EM Physician Case Continued He was completely stable, so adenosine was administered. See Learning point 1 below.

It is seldom done in pediatric age group. They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. With proper precautions, risk can be reduced.

What kind of AV block is this? And why does she develop Ventricular Tachycardia?

Dr. Smith's ECG Blog

Shortly after isoprenalin infusion was initiated, there were short runs of ventricular tachycardia. Extensive conduction system abnormalities can have various causes (ischemia, genetic, infectious, amyloid, etc). During the next 24 hours, she experienced periods of complete AV block with a ventricular escape rhythm in the 20s.

Hyperthermia and ST Elevation

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
