Overview

Low per-test complication rate without lasting harm supports safety hypothesis in high-risk patients; leaves open need for prospective confirmation.

Structured PICO

Is maximal exercise testing safe in patients at high risk for ventricular arrhythmia?

P
Population
263 patients with malignant ventricular arrhythmias (74% with a history of ventricular fibrillation or hemodynamically compromising ventricular tachycardia, and the remainder with ventricular tachycardia in the setting of recent myocardial infarction or poor left ventricular function)
I
Intervention
Maximal treadmill tests (symptom-limited exercise testing)
O
Outcome
Complications during exercise testing (defined as ventricular fibrillation, ventricular tachycardia, or bradycardia mandating immediate medical treatment such as cardioversion, intravenous drugs, or closed-chest compression)safety

Maximal exercise testing in patients with malignant ventricular arrhythmias is associated with a low rate of complications per test (2.3%) and no lasting morbid events, supporting its safety in this high-risk population.
