The difference between video-EEG and 24-hour ambulatory EEG

EEG waveform reflects the situation of EEG activity, generally in children, EEG is the most widely used in the diagnosis of epilepsy. Some epilepsy occurs during the onset of EEG abnormalities, in remission performance is normal. So in order to better diagnose the condition, we have different forms of EEG examination. Ltd.

Video EEG generally reflects the changes of EEG in a short time, while 24-hour dynamic EEG reflects the activities of EEG in a day. They have their own advantages and disadvantages:

(1) Video electroencephalogram (VEEEG) is used to detect EEG activity in detail, but the response time is too short.

(2) 24-hour ambulatory electroencephalogram (AEEG) reflects long-term changes of EEG, but it is not precise enough to explain specific problems. Generally, in the process of clinical selection, if the patient has symptoms and video-EEG has no obvious manifestation, it is necessary to choose 24-hour dynamic EEG observation, which has important diagnostic value for the onset of absence. Ltd.

What does dynamic electrocardiogram tell you about premature beats? Simple premature beats are not heart disease!

In the normal and regular beating process of the heart, the sudden occurrence of premature beating becomes "premature beating" in medicine, abbreviated as "premature beating". Premature heart beat is one of the common arrhythmias. It can occur not only in some patients with heart disease, but also in normal people. Ltd.

Premature beats can be classified into benign and malignant ones. The former does not require treatment or improvement of symptoms, while the latter requires admission for observation in order to avoid myocardial damage. Experts point out that premature beats can also occur in normal people, and simple premature beats can not simply be considered to be related to heart disease.

First, many young patients are registered for premature beats. About 10% to 20% of patients with premature beats have no symptoms in the prophase, only found during physical examination. Most people feel uncomfortable, such as panic, palpitation, arrhythmia and so on. Young people may be attributed to mental stress, physical weakness, heavy drinking of coffee and tea and other factors.

Secondly, many people will be nervous when they see the diagnosis result of "abnormal electrocardiogram, premature beats" written on the physical examination report, but benign premature beats will occur in normal people without heart disease, so there is no need to worry too much. Many people with benign premature beats worry that they have heart disease, which will aggravate the symptoms of the disease.

Third, patients with premature beats can make a 24-hour ambulatory electrocardiogram, if the number is less than 100, it belongs to benign. If the number is more than 100 and the electrocardiogram is abnormal, it is probably not benign.

Fourth, non-benign premature beats can induce ventricular tachycardia and ventricular fibrillation, which are very dangerous and can easily lead to sudden death. It is suggested that such patients should be treated actively, including drug therapy and radiofrequency ablation. Among them, drug treatment can only improve the symptoms of discomfort, and only surgery can completely eliminate the pain of the disease.
