Holter electrocardiogram (Holter monitoring)

Dynamic electrocardiography is a method that continuously records and compiles ECG changes in the active and resting state for a long time. Also known as Holter monitoring. Basic Information Specialist classification: cardiovascular examination classification: electrocardiogram Applicable gender: whether men and women apply fasting: not fasting Tips: Please turn off your phone on the day of check. Do not wear a dress when checking. Normal value Conventional ECG can only record waveforms with a resting state of only a few dozen cardiac cycles, while dynamic electrocardiogram can continuously record up to 100,000 ECG signals within 24 hours, which can improve non-sustained ectopic rhythm, especially It is the detection rate of transient arrhythmia and transient myocardial ischemic attack. Clinical significance 1. Diagnosis of myocardial ischemia. 2. Evaluate various symptoms that may be related to the heart. 3. Evaluation of anti-myocardial ischemia and anti-arrhythmia drug therapy. 4. Evaluation of pacemaker function. 5. Follow-up of patients with myocardial infarction. 6. Diagnosis of normal heart rhythm. Precautions Dynamic ECG check notes: 1. Please see the doctor on time, out of date, if you need to change the time, please consult one day in advance. 2. Those who have done this check, please bring the original report for comparison. 3. Please clean the chest area before the examination. If you have a chest hair, shave it yourself to ensure the quality of the examination. 4. Do not wear a dress when checking. 5. It is strictly forbidden to open the recorder privately. 6. Please turn off the phone on the day of inspection. 7. Three days after the end of the examination, go to the outpatient ECG room to take the report. Inspection process 1. The examinee is best hospitalized for examination, so that the tape movement in the recording box can be observed at any time. A 12-lead conventional electrocardiogram is used as a control before the examination. 2. Using a mixture of absolute ethanol and diethyl ether, wipe off the surface oil of the skin where the subject is placed. 3. Leads select the anatomical positioning of each commonly used simulated lead as follows. (1) Simulated V1 (CM1): The positive electrode is located 2.5 cm beside the sternum of the right fourth intercostal space; the negative electrode is located at 1/3 of the right subclavian lower fossa. (2) Simulated V2 (CM2): The positive electrode is located 2.5 cm beside the sternum of the left fourth intercostal space; the negative electrode is located at 1/3 of the right subclavian lower fossa. (3) Simulated V5 (CM5): The positive pole is located in the left fifth intercostal iliac crest front line; the negative pole is located in the middle third of the left subclavian lower fossa. (4) Simulated aVF (MaVF): The positive pole is located at the rib margin of the left anterior iliac crest; the negative pole is located at 1/3 of the lower clavicle lower fossa. (5) No dry electrode: 1/3 of the right subclavian lower fossa, or the fifth intercostal anterior line of the right chest or the middle part of the lower sternum. 4. Place the positive electrode at two places, V1 and V5. Place the negative electrode on the left and right sides of the clavicle on the chest and place the ground wire on the sternum handle. Or put the positive electrode at V1, V5, the two negative electrodes are placed at the sternum handle, and the ground wire is placed on the right chest, which is equivalent to V5R. 5. Explain the precautions to the inspected person, and explain the valuableness of the recorder, so that the examinee can record the eating and drinking, work and physical exercise, etc. during the recording period, and all activities are not restricted. 6. Keep away from high-voltage electricity places during the inspection process, such as radiology and physiotherapy rooms. 7. At the end of the inspection, remove the electrode, wipe the electrode clean, check if the lead is unobstructed, and prepare for the next use. 8. Remove the recording tape and place it on the imager for ECG image analysis to record important ECG changes. Count or print out abnormal change data and ECG. Not suitable for the crowd There are generally no special contraindications. Adverse reactions and risks Generally no adverse reactions.
