Performance test

A Holter ECG test involves recording ECG continuously over 24 hours. This examination makes it possible to assess the various types of changes occurring in the heart under specific conditions (during the day, at night, during sleep, during exercise and during eating). In this way, dynamic changes occurring in the heart are diagnosed.

ECG Holter - Symptoms and course

The Holter ECG is a painless test in which changes in heart rhythm, conduction, blood supply or electrolyte problems in the heart are monitored over 24 hours. With a momentary (resting) ECG recording of changes in the heart, it is not possible to capture any abnormalities.

The patient, after appropriate skin preparation, has special electrodes applied to the skin at specific locations. These are connected to a memory medium on which the ECG recording is stored. The patient has and can function normally during the 24 hours of the test. A review of the recorded graph takes place on a monitor in the Hospital.

Indications for an EGK Holter recording are:

  • frequent attacks of dyspnoea,
  • fluttering and palpitations,
  • syncope,
  • heart rhythm disturbances,
  • assessment of the function of an implanted pacemaker
  • accompanying additional symptoms such as headaches and a feeling of heaviness, sudden hot flashes and sweats.

During the examination, the patient should keep a diary with notes (whether there were any symptoms and when, what might have caused them, how long they lasted) and should not take a bath.

It is a completely safe test but very useful in the case of all sorts of problems such as cardiac arrhythmia.
