What Is an Ambulatory ECG?

The 24-hour dynamic electrocardiogram is a long-term continuous recording and compilation analysis of the changes in the electrocardiogram of the human heart under active and quiet conditions. Including: ST level trend chart, heart rate variability, data after physical exercise and differential diagnosis of various arrhythmia. Qualitative and quantitative diagnosis of arrhythmia and myocardial ischemia, determination of the causes and properties of paroxysmal syncope, dizziness, and palpitations, evaluation of drug efficacy, and evaluation of pacemaker function. Can record all abnormal radio waves, can detect all kinds of arrhythmia and patients with or without asymptomatic myocardial ischemia in each state within 24 hours, provide accurate and reliable basis for the diagnosis of heart disease. In clinical applications, Especially for early coronary heart disease has a higher detection rate.

You can move freely while doing dynamic electrocardiogram, it will not affect daily life, do whatever you want to do.

This test is performed by attaching multiple electrode pads to the front of the chest. The more electrode pads, the more comprehensive the record is, generally less than 10.

It is often difficult to capture an effective diagnostic basis for an ECG, but the patient has obvious consciousness

24-hour dynamic ECG

In case of symptoms, the doctor advises them to perform ECG dynamic monitoring.

1. Detection of occult arrhythmias: transient, arrhythmias that occur only under certain circumstances, and conventional ECGs are easy to miss, while DCG can capture transient abnormal ECG changes, understand the origin, duration, frequency, occurrence and termination of arrhythmias Regularity can be analyzed synchronously with clinical symptoms and daily activities.

2. Monitoring tachyarrhythmias: You can further understand the occurrence and termination of the disease, whether it is accompanied by SSS syndrome or preexcitation syndrome (WPW syndrome, especially intermittent) and its typing.

3. Observe bradyarrhythmias: understand its main manifestations and whether there is sinus node dysfunction. For fast-slow syndrome, through DCG observation, assist in the selection of antiarrhythmic drugs, adjust the dose or consider other treatment methods, and provide an objective basis for the installation of pacemakers and type selection.

4. Assist in judging the clinical significance of different types of ectopic rhythms or conduction blocks: monitor their frequency and severity through DCG, and determine the corresponding relationship with daily life or activities, and determine treatment guidelines.

5. Evaluating the efficacy of antiarrhythmic drugs: DCG is a reliable clinical indicator for studying and evaluating antiarrhythmic drugs.

6. Potential risk factors for sudden death were found. The most common cause of sudden cardiac death is ventricular tachycardia or ventricular fibrillation. Ventricular arrhythmias with unstable ECG activity often occurred before the occurrence. It can only be found by DCG. For patients with mitral valve prolapse, hypertrophic or dilated cardiomyopathy, and prolonged QT syndrome who may have sudden death, DCG can find the risk factors of sudden death in a timely and comprehensive manner, which helps to take timely and effective treatment measures.

7. Assist in judging whether intermittent symptoms such as chest tightness, palpitations, dizziness, haze or syncope are cardiogenic.

8. DCG continuously monitors 12-lead ECG and has a high detection rate of myocardial ischemia. It can also perform localized diagnosis, especially atypical myocardial ischemia. Myocardial infarction or asymptomatic myocardial ischemia has irreplaceable clinical value. ST-T changes and time-synchronized activity-related analysis can help determine the type of myocardial ischemia and select drugs. In addition, the type and frequency of arrhythmias associated with myocardial ischemia can be detected, and the possibility of sudden cardiac death can be predicted, which facilitates early prevention and treatment measures.

Patients need to pay attention to:

1. After putting on the record box, the patient can perform daily activities such as going to work, walking, and simple housework.

2. It is necessary to avoid strenuous physical exercise and avoid contact with strong magnetic and electric fields. In order to avoid distortion of the ECG waveform and excessive interference, which will affect the diagnostic report.

3. Patients are required to record logs throughout the monitoring process, to record activity status and related symptoms according to time. A detailed and complete life log is of important reference value for the correct analysis of dynamic ECG data.

4. Dynamic ECG is often affected by patient's position, activity, mood, sleep and other factors during the monitoring process. Therefore, the results detected by dynamic ECG should be combined with medical history, symptoms and other clinical data to make a correct diagnosis. The inspection fee varies from place to place. (Shanghai Hua X Hospital, Top Three) is 160 yuan / time. Hospitals in different parts of the country have different levels, and prices may fluctuate.
