The Claim
Patients with vasovagal syncope have a lower Index of Cardiac Electrophysiological Balance (ICEB) compared to healthy individuals, independent of age, sex, and blood pressure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who experience vasovagal syncope have a measurably lower Index of Cardiac Electrophysiological Balance than healthy individuals, even when accounting for age, sex, and blood pressure.
See the scientific wording
The Index of Cardiac Electrophysiological Balance (ICEB) is lower in patients with vasovagal syncope than in healthy individuals, independent of age, sex, and blood pressure, suggesting it may serve as a noninvasive biomarker reflecting underlying autonomic imbalance.
In people with vasovagal syncope, the nervous system keeps the heart under constant parasympathetic control, which speeds up the heart's recovery phase after each beat. This makes the electrical reset happen faster without changing the initial signal timing, resulting in a lower ratio between the repolarization and depolarization phases on the ECG.
What the research says
1 studyScientists found that people who faint from vasovagal syncope have a lower ICEB score on their ECG than healthy people, even when accounting for age, sex, or blood pressure — suggesting ICEB might be a simple way to spot an imbalance in the body’s automatic nervous system.
