In plain English

In people with structural heart disease, palpitations often result from arrhythmias that are associated with a high risk of sudden cardiac events.

See the scientific wording

In individuals with structural heart disease, palpitations are frequently caused by arrhythmias that indicate high risk of sudden cardiac events.

Why this might work

Abnormal heart tissue creates electrical short circuits that cause the heart to beat too fast or irregularly, which feels like palpitations and can suddenly stop the heart from pumping blood.

What the research says

3 studies

  1. Study: Determinants of recurrence after epicardial ventricular tachycardia ablation in structural heart disease.

    In people with heart structure problems, this study found that dangerous heart rhythm problems (VT) often come back and can lead to death or needing a transplant — and these rhythm problems are what cause the fluttering feeling in the chest (palpitations). So yes, those fluttering feelings are often a sign of something serious.

  2. Study: Malignant Ventricular Arrhythmia With Apical Biventricular Noncompaction

    In people with heart structure problems, feeling your heart race (palpitations) can sometimes mean you have a dangerous heart rhythm that could cause sudden cardiac arrest — this case shows exactly that happening.

  3. Study: Supraventricular Tachy-arrhythmia Revealing an Arrhythmogenic Right Ventricle Cardiomyopathy in An Adolescent: Case Report

    In people with a specific heart condition called ARVC, feeling your heart race (palpitations) often means there’s a dangerous heart rhythm that could lead to sudden cardiac arrest. This case shows that even teens can have this problem.
