The Claim

Severe arrhythmia burden in the context of apical biventricular noncompaction can induce life-threatening ventricular fibrillation requiring defibrillation and ICD implantation, even in the presence of preserved systolic function.

Cause and effect
1 study reviewed
In plain English

In individuals with apical biventricular noncompaction and a high percentage of premature ventricular contractions, ventricular fibrillation can occur during cardiac testing, requiring emergency defibrillation and implantation of a device to prevent sudden cardiac arrest, even when the heart's pumping ability is normal.

See the scientific wording

A 15-year-old girl with apical biventricular noncompaction and a 26% PVC burden experienced inducible ventricular fibrillation during an electrophysiology study, requiring defibrillation and implantation of a single-chamber ICD, demonstrating that severe arrhythmia burden in the context of this structural abnormality can lead to life-threatening events even with preserved systolic function.

Why this might work

Abnormal heart muscle structure creates tangled pathways that let electrical signals loop back on themselves, causing the heart to beat wildly and stop pumping blood effectively.

  1. Study: Malignant Ventricular Arrhythmia With Apical Biventricular Noncompaction

    A teenage girl with a rare heart structure had a scary heart rhythm that almost killed her during a heart test, so doctors put in a device to shock her heart back to normal if it happens again — proving that even kids with otherwise healthy hearts can have dangerous heart problems from abnormal beats.
