May indicate catecholamine-sensitive PVC triggers in MVP; leaves open prospective validation for arrhythmia risk.
How does heart rate affect the frequency of premature ventricular complexes in patients with mitral valve prolapse?
In patients with mitral valve prolapse, premature ventricular complexes are predominantly fast-heart-rate-dependent, suggesting a catecholamine-sensitive trigger mechanism for ventricular arrhythmias.
Bugge et al. (2026) studied this question.
