We live in a variety of languages, like English, French, and Italian, which help us communicate with the world. But actually you know? Your body will also speak, it will tell you your physical state in a special language, but to hear its language and understand its meaning, you need specialized equipment and professional knowledge.
One of the language signals today is ventricular late potentials (VLP). Ventricular late potential is an awkward medical term for ordinary people. For doctors, this is a weak signal. It is closely related to ventricular tachycardia, ventricular fibrillation and sudden death, in predicting the occurrence of related diseases. Evaluation of the therapeutic effects of related drugs has important clinical value. Especially in the early warning of myocardial infarction, cardiomyopathy, ventricular aneurysm and other diseases have a high reference value.
Let's take a brief look at the history of the development of ventricular late potential.
In the development of ventricular late potential research, you will find that scientists in the laboratory with good shielding conditions, spent a lot of energy to slowly detect the ventricular late potential. Why is the ventricular late potential so difficult to detect, so that scientists have to spend so much time? This is caused by the ventricular late potential characteristic, which is the "cracking potential" appearing on the electrocardiogram after the QRS wave, that is, the high-frequency (25-300 Hz) signal belonging to the microvolt level, so it cannot be used in the electrocardiogram machine commonly used in our hospital physical examination. Get records. Explained in plain language, someone is talking to you, but the voice is too light, so it is hard to hear clearly.
If it is in daily life, it is not important for others to talk to you without hearing. However, ventricular late potential as a warning signal for cardiovascular disease, not detected, it can be a big deal. The ventricular late potential signal is also susceptible to interference in addition to the weak signal, which is extremely unfavorable for the diagnosis of the disease. Based on this situation, Professor Zhang Tongsheng of Mansenberg has led a team to develop a new filtering technology, Pre-Sig Detection ECG filtering technology, which can greatly increase the effective ECG signal acquisition frequency, and is effective with advanced algorithms. The problem that the ventricular late potential is disturbed during the signal extraction process and the signal distortion is solved is solved. This way, even in a well-shielded laboratory, but in a normal living environment, the ventricular late potential can still be detected, which is equivalent to having a pair of downwind ears, even if the sound is very weak, and there is noise interference next to it, so you can still listen. Clear. The invention of this technology effectively solves the problem of detection of ventricular late potential, and has great significance for early warning of diseases such as myocardial infarction, cardiomyopathy and ventricular aneurysm.
The advancement of science brings more guarantees to the lives and health of the people. As a high-tech company in the field of weak signal extraction, Mansenberg will continue to increase investment in technology research and development, bringing value to cooperative enterprises and society.
