Das Langzeit-EKG in der Neurologie
Long-term ECG in Neurology: Focusing on the Heart-Brain Axis
In modern neurology, we view the body as an interconnected system. The close connection between the heart and the nervous system – often referred to as the heart-brain axis – plays a crucial role in the diagnosis and prevention of serious diseases.
1. The Close Connection Between the Nervous System and the Heart
The heart and the nervous system are in constant interaction. The brain controls the heartbeat via the autonomic nervous system, while the heart supplies the brain with vital oxygen. Many neurological symptoms or diseases actually have their origin in the heart. Therefore, cardiological evaluation is indispensable in neurology.
2. Vital Importance in Stroke
Cardiac arrhythmias are among the most common causes of strokes. In particular, atrial fibrillation and various tachycardic arrhythmias (excessively fast heartbeat) can lead to the formation of blood clots in the heart, which then travel to the brain and block a vessel there.
A long-term ECG is therefore:
- An essential examination for all stroke patients.
- Ideally performed within a few days of the event to identify the cause as quickly as possible.
- To be repeated regularly in the further course, as some rhythm disturbances only occur sporadically.
Our Goal: We want to reliably determine whether a stroke was caused by atrial fibrillation or another treatable cardiac arrhythmia in order to effectively prevent a recurrence (secondary prevention).
3. Diagnostics for Sleep Disorders
Another important area of application for the long-term ECG in our practice is the investigation of sleep disorders. For patients with breath-dependent sleep disorders, such as obstructive sleep apnea, the ECG serves as an important supplementary diagnostic tool.
While the sleep disorder is primarily diagnosed using polygraphy (sleep screening), we recommend an additional long-term ECG if respiratory arrests are detected. The reason: nocturnal breathing pauses place massive stress on the heart and can provoke dangerous rhythm disturbances that often go undetected in a standard daytime ECG.
4. Summary
In neurology, a long-term ECG is much more than just a heart examination. It is a central diagnostic method for:
- Precise clarification of stroke causes.
- Early detection of cardiac arrhythmias.
- Important supplementary diagnostics for sleep-related breathing disorders.
Through this holistic diagnostic approach, we ensure that neurological symptoms are recognized and treated at their root.
