24 hour Holter monitoring

What is 24-hour Holter monitoring?

It is a method of comprehensive diagnosis of the performance of the cardiovascular system. During the test the data on cardiac electrical activity is being recorded (usually within 24-hours), unlike standard ECG.

It records the heartbeat, cardiac contraction rhythm, the presence or absence of cardiac contraction disorders. This method is often paired with measuring blood pressure.

ECG and/or blood pressure Holter monitoring helps to identify:

  • cardiac rhythm disorders, heart blocks.
  • the signs of cardiac blood supply disturbance, myocardial ischemia.
  • hypertension and hypotension.
  • the reason for syncope.
  • cardiac disorders in the context of usual daily routine (with usual and high physical or emotional load).

The test performed simultaneously with drug intake helps to adjust the dosage of drugs for the treatment of cardiovascular disorders.

Holter monitoring at Kivach Clinic

The test is carried out using modern equipment which does not interfere with the patient’s daily routine.

The test is prescribed by an attending physician or cardiologist based on the following indications:

  • the feeling of disruptions in heart performance;
  • tachycardia or bradycardia;
  • angina;
  • elevated blood pressure;
  • lower exercise tolerance;
  • adjusting the dosage of cardiovascular drugs;
  • changes, detected by ECG, that show cardiac rhythm disorders.

For patients with a high risk of sleep apnea, excess weight, snoring, sleep disorders, and in order to examine the cardiovascular system there is cardiorespiratory monitoring.

What to expect during the test?

The test is carried out similarly to the cardiorespiratory monitoring. Contraindications and preparations are the same as well. Learn more.
