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. In a child with suspected sinus node dysfunction, chronotropic incompetence from sinus node dysfunction can be assessed by exercise testing.

Electrophysiological Characteristics and Ablation Outcomes in Patients With Catecholaminergic Polymorphic Ventricular Tachycardia

Journal of the American Heart Association

The primary end point was syncope recurrence, and the secondary end point was the reduction of the ventricular arrhythmia score during exercise testing. Twenty‐six PVT/ventricular fibrillation–triggering PVCs were identified for ablation. Induction of nontriggering PVCs after ablation is associated with a higher risk of syncope recurrence.

Cardiac resynchronization using fusion pacing during exercise

Journal of Cardiovascular Electrophysiology

Abstract Introduction Fusion pacing requires correct timing of left ventricular pacing to right ventricular activation, although it is unclear whether this is maintained when atrioventricular (AV) conduction changes during exercise. QRSd during exercise ( p  = .03), 03), peak O 2 pulse (mL/beat, a surrogate of stroke volume, p  = .03),

PO-02-097 SCAR BURDEN DETERMINED BY MRI IS ASSOCIATED WITH EXERCISE RELATED CHANGES IN ACTIVATION PATTERN IN HYPERTROPHIC CARDIOMYOPATHY

HeartRhythm

LGE scar burden on MRI is thought to contribute to this risk, but its impact on electrophysiological substrate is not well understood. Hypertrophic cardiomyopathy (HCM) is associated with a predisposition to lethal ventricular arrhythmias.
