Holter ECG (Holter) – this is the method by which the daily monitoring of the functioning of the heart and is a widely used method of functional diagnostics. This method is used in clinical diagnosis, not only to detect cardiac arrhythmias and ischemic changes on elektrokaridiogramme, but also for monitoring antiarrhythmic and antianginal therapy. It uses a portable recorder (it is located within a day the patient), which produces a clock ECG recording and transmitting information about the work of the heart for one day in the computer. Special software allows the identification and analysis of all irregular heartbeat, painful and painless episodes of myocardial ischemia. This method allows not only to make the diagnosis, but also greatly enhance the effectiveness of the treatment of cardiovascular diseases (hypertension, infarction, atherosclerosis, myocarditis). Indications for Holter monitoring 1-Complaints, which may be due to heart rhythm disturbances (palpitations, fainting, dizziness). 2 Assessment of risk occurrence terrible, life-threatening arrhythmias in patients with no complaints at: a) hypertrophic cardiomyopathy, and b) recent myocardial infarction complicated by heart failure or rhythm disturbances, and c) an elongated syndrome QT. 3 Evaluation antiarrhythmic treatment, or manifestations of proarrhythmic effects.
4 Evaluation of pacemaker: a) patients with complaints that can be suspected arrhythmia, and b) in cases of individual programming pacemaker, for example, establish the upper frequency limit of the tendency to tachycardia rate or rhythm correction taking into account the activity of the patient. 5 Rating insufficient blood supply to the heart muscle: a) a suspected variant Prinzmetal angina type b) in exceptional cases after acute myocardial infarction to determine the future tactics of the patient, c) in exceptional cases of coronary heart disease to assess the effectiveness treatment. 6 Evaluation of the cyclic variability of sinus rhythm in patients with: a) myocardial infarction, and b) with heart nedostatochnostyuv) with suspected dysfunction of the autonomic system, such as diabetes or sleep apnea syndrome. The method of daily monitoring of ECG is absolutely safe for the patient, cardiologist and appears a natural desire to hold it for each patient. Indeed, practice confirms that there is no cardiac patients, of whom Holter ECG monitoring would not give further details.
