The 24-hour ambulatory electrocardiogram (ECG) is a method of long-term continuous recording and compilation and analysis of the heart of a person in an active and quiet state. It includes: St-segment trend graphs, heart rate variability, post-exercise data and differential diagnosis of various heart rate disorders.
To be tested for 24 hours.
Qualitative and quantitative diagnosis of arrhythmias and myocardial ischemia, determination of the etiology and characteristics of paroxysmal syncope, vertigo and palpitations, and evaluation of drug efficacy and pacemaker function.
It can record all abnormal electrical waves and detect various arrhythmias and symptomatic myocardial ischemia within 24 hours, providing an accurate and reliable basis for the diagnosis of heart disease. It has a high detection rate in clinical application, especially in early coronary heart disease.
Precautions:
After wearing the recorder, you can carry out daily activities, such as work, walking, simple housework, etc., avoiding strenuous exercise, avoiding contact with strong magnetic and electric fields, avoiding distortion of the ECG waveform and too much intervention, which will affect the diagnostic report, and throughout the whole monitoring process, the patient is required to record the logbook, the state of activity and related symptoms according to time.
A detailed and complete life log is an important reference value for correctly analyzing the data of the ambulatory electrocardiogram, which is often affected by the patient's position, activity, mood, sleep, and other factors during the monitoring process.
Therefore, the results of the ambulatory electrocardiogram should be analyzed in conjunction with the history, symptoms, and other clinical data to make a correct diagnosis.
The price may fluctuate due to different prices in different regions and if the hospitals are of different levels.

Expanded Information;
Hidden Detection of arrhythmia: an arrhythmia that occurs in a short period of time and under specific circumstances. Conventional ECG can easily miss the diagnosis, while DCG can capture short-term abnormal ECG changes to understand the origin, duration, frequency, onset and termination of the arrhythmia, as well as analyze its relationship with clinical symptoms and daily activities.
Monitoring of tachyarrhythmias: further understanding of their onset and termination, and observation of slow arrhythmias. To understand the main manifestations of slow arrhythmias and the presence of sinus node dysfunction. For fast and slow syndromes, DCG observation helps in the selection of antiarrhythmic drugs, adjustment of dosage or consideration of other therapies, and helps to determine the clinical significance of different types of ectopic rhythms or conduction blocks.
The frequency and severity of their occurrence and their correspondence with daily life or activities are monitored by DCG to determine therapeutic strategies and evaluate the efficacy of antiarrhythmic drugs.
DCG is a reliable clinical indicator for the study and evaluation of antiarrhythmic drugs. The most common cause of sudden death is ventricular tachycardia or ventricular fibrillation. Sudden cardiac death is often preceded by ventricular arrhythmias with unstable cardiac activity, which can only be detected by DCG.
For patients with mitral valve prolapse, hypertrophic or dilated cardiomyopathy, Q-T prolongation syndrome and other possible sudden deaths, DCG can promptly and comprehensively identify the risk factors for sudden death, which helps to take timely and effective therapeutic measures, and helps to determine whether intermittent symptoms due to chest tightness, palpitations, dizziness, blackout, or fainting are all cardiogenic.
DCG continuous monitoring of 12-lead electrocardiogram has a high detection rate of myocardial ischemia and can also be used to localize the diagnosis, especially for symptoms of atypical myocardial ischemia. It has irreplaceable clinical value in myocardial infarction or asymptomatic myocardial ischemia.Correlation analysis of ST-T changes with time-synchronized activity helps in the determination of the type of myocardial ischemia and the selection of drugs.
In addition, the type and frequency of arrhythmias with myocardial ischemia can be detected to predict the likelihood of sudden cardiac death so that early preventive measures can be taken.
