About me
Li Haiwen, a master's degree student, associate chief physician, has been engaged in clinical cardiology and cardiovascular disease intervention for 9 years. In 2015, he was transferred from the Cardiology Department of Hainan Medical University Affiliated Hospital to the Cardiology Department of Guiyang Second Traditional Chinese Hospital. He has studied for one year respectively at the Guangdong Cardiovascular Institute and the Cardiac Catheterization Lab of West China Hospital, Sichuan University, focusing on radiofrequency ablation for cardiac arrhythmias and pacemaker intervention therapy. He has passed the Ministry of Health's entrance examination for pacemaker and electrophysiology intervention physicians. He has also undertaken a short-term study visit at the Electrophysiology Center of Korea Goryeo University. His main research direction is the intervention diagnosis and treatment of cardiovascular diseases, with proficiency in pacemaker implantation (temporary and permanent pacemakers) and coronary intervention therapy as well as left ventriculography.

Principles of treatment for ventricular premature beats
The treatment of ventricular premature beats mainly includes the following aspects: First, palliative treatment. Palliative treatment refers to cases where the patient's ventricular premature beats do not occur frequently, and there are no clinical symptoms, and no organic heart disease is found through related cardiac echocardiography. For this type of ventricular premature beats, treatment is not necessary, and regular observation can be conducted, which we call palliative treatment. Second, medication treatment. When ventricular premature beats occur frequently, and the patient has obvious clinical symptoms, such as palpitations and chest tightness, treatment can be carried out under the guidance of a doctor with standardized medication. Third, surgical treatment. When premature beats occur frequently and severely affect the patient's quality of life, radiofrequency ablation treatment can be conducted, and this treatment potentially cures ventricular premature beats.
Mild pulmonary hypertension
Pulmonary hypertension is a relatively common disease in daily life. Many patients, when they go to the hospital for examination, often see reports from cardiac ultrasound indicating mild pulmonary hypertension, moderate pulmonary hypertension, or non-severe pulmonary hypertension. So, what are the criteria for mild pulmonary hypertension? Generally, pulmonary artery pressure is measured using right heart catheterization or cardiac ultrasound. If the pressure is between 30 to 50 mmHg, this is often considered mild pulmonary hypertension. Generally, the prognosis for mild pulmonary hypertension is quite good, typically not producing noticeable symptoms or affecting health.
How is atrial fibrillation treated?
Atrial fibrillation is a common type of arrhythmia in our daily lives, and it has many dangers. First, it produces symptoms; when atrial fibrillation occurs, patients often experience palpitations and chest discomfort. Second, it can induce heart failure. Third, it can cause complications such as cerebral infarction. Therefore, the treatment of atrial fibrillation is usually divided into the following types: first, pharmacological treatment, such as using amiodarone to maintain sinus rhythm and taking warfarin to prevent thrombosis. Second, surgical treatment, such as radiofrequency ablation therapy, which is a minimally invasive method and is hoped to prevent further episodes of atrial fibrillation.
What to do with mild pulmonary hypertension?
Pulmonary artery hypertension is a relatively common disease in daily life. Based on the different pulmonary artery pressures, it can be divided into mild, moderate, and severe pulmonary artery hypertension. When the right heart catheter measures pulmonary artery pressure between 30 to 50 mmHg, this situation often belongs to mild pulmonary artery hypertension. So, what should one do if diagnosed with mild pulmonary artery hypertension? Generally, mild pulmonary artery hypertension is not serious and usually does not cause noticeable symptoms, so no special treatment is needed. However, having mild pulmonary artery hypertension does not mean it can be taken lightly. It is important to undergo regular examinations under the guidance of a doctor, identify the cause of the increased pulmonary artery pressure, and treat the symptoms timely.
Can ventricular premature beats cause dizziness?
Ventricular premature beats are a relatively common occurrence in our daily lives. Whether ventricular premature beats can cause dizziness is a question that requires specific analysis of each individual case. If ventricular premature beats occur frequently, they may lead to reduced cardiac pumping function or decreased cardiac output, thereby causing symptoms of hypoxia, which might include dizziness. Besides dizziness, other symptoms such as palpitations and chest tightness may also occur due to hypoxia. Conversely, if ventricular premature beats only occur occasionally, they generally do not cause dizziness.
Can atrial fibrillation be cured?
Can atrial fibrillation be cured? Many patients often ask doctors this question, and the answer is affirmative. With the development of minimally invasive interventional treatment techniques, some patients with atrial fibrillation have been cured after radiofrequency ablation treatment and have not experienced any recurrence. As for which atrial fibrillation cases are suitable for radiofrequency ablation treatment, I suggest that if the atrial fibrillation recurs repeatedly and the symptoms are quite apparent, and the effect of medication is not ideal, one should consult a specialist cardiologist to see if radiofrequency ablation treatment is appropriate.
Atrial fibrillation symptoms
Atrial fibrillation is a common type of arrhythmia we encounter in our daily lives. So, what symptoms generally accompany atrial fibrillation? These symptoms are often characterized by sudden onset and cessation of palpitations, or chest tightness. During palpitations or chest tightness, dizziness often accompanies, and some patients may experience chest pain. If you exhibit these symptoms, don't panic. You can visit the cardiology outpatient department at a hospital. There, a doctor can perform an electrocardiogram or a Holter monitor test to see if you have atrial fibrillation. Blood tests can also be done to check if hyperthyroidism, a potential cause of atrial fibrillation, is present. Based on these examinations, follow the doctor's guidance and take medications as prescribed for treatment.
What is good to eat for atrial fibrillation?
Atrial fibrillation is a common type of arrhythmia in the elderly. After being diagnosed with atrial fibrillation, there are indeed some dietary considerations to be aware of. Here are a few aspects to pay attention to: First, eat less spicy and greasy food. Spicy and greasy foods can often irritate our stomach, leading to discomfort and potentially triggering an episode of atrial fibrillation. Second, eat more vegetables and fruits. Vegetables and fruits are often rich in dietary fiber and vitamin C, which are beneficial to our health. Third, balance meat and vegetable intake and ensure nutritional balance. Foods such as pork, fish, and lean meats are rich in high-quality protein, which is beneficial for our health.
What does sudden cardiac death mean?
Sudden cardiac death refers to the sudden mortality caused by heart diseases, and the reasons for sudden cardiac death primarily include the following aspects: First, structural heart diseases, such as coronary heart disease and acute myocardial infarction; acute myocardial infarction is currently the most common cause of sudden cardiac death. Second, certain ion channel diseases, such as Brugada syndrome, or long QT syndrome. These types of ion channel diseases often coincide with malignant ventricular arrhythmias, such as torsade de pointes ventricular tachycardia or ventricular fibrillation, thus leading to the occurrence of these fatal phenomena. Third, severe arrhythmias, such as severe bradycardia or ventricular tachycardia related to structural heart disease, often trigger malignant ventricular arrhythmias, leading to death.
Is severe mitral valve regurgitation serious?
Mitral valve regurgitation can be mild, moderate, or severe, with severe mitral valve regurgitation being the most serious. Over time, severe mitral valve regurgitation can cause enlargement of the heart and a decreased heart pumping function, eventually leading to symptoms of heart failure. Patients may experience difficulty breathing, shortness of breath, fatigue, and other symptoms. Additionally, there may be swelling in both lower limbs. When such symptoms occur, it is necessary to take diuretic medications under the guidance of a doctor to reduce heart strain, such as furosemide or spironolactone. If necessary, digoxin may be taken to strengthen the heart and improve symptoms of heart failure. After stabilization, a mitral valve replacement or repair surgery may be scheduled.
