Left ventricular false tendons, often found in young athletes, are linked to repolarization abnormalities on electrocardiograms. These ECG changes typically resolve with increased heart rate during exercise tests.
Area of Science:
- Cardiology
- Sports Medicine
- Diagnostic Imaging
Background:
- Left ventricular false tendons are common anatomical variations.
- Ventricular repolarization abnormalities can be associated with cardiac conditions.
Purpose of the Study:
- To characterize left ventricular false tendons using echocardiography.
- To investigate the correlation between false tendons and repolarization abnormalities in young athletes.
Main Methods:
- Echocardiography and 12-lead electrocardiograms (ECG) were performed on 316 young athletes.
- Athletes with abnormal T-waves underwent further echocardiogram and exercise testing.
- Heart rate and blood pressure were monitored during exercise.
Main Results:
- False tendons were identified in 6.9% of athletes, predominantly in the inferior septum to lateral wall.
- Ventricular repolarization abnormalities, mainly T-wave changes (V1-V3), were found in 52.38% of those with false tendons.
- ECG abnormalities resolved with increased heart rate during step and maximal exercise tests.
Conclusions:
- Left ventricular false tendons are frequently located between the inferior septum and lateral wall.
- A statistical association exists between left ventricular false tendons and ventricular repolarization abnormalities in young athletes.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
