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.
Proficient in diseases
Specializing in radiofrequency ablation for arrhythmias, able to make rapid and accurate diagnoses and perform radiofrequency ablation treatment for various supraventricular tachycardias. Proficient in independently using the CARTO 3.0 system and Ensite Velocity system to perform radiofrequency ablation treatment for complex arrhythmias such as atrial flutter (left atrium, right atrium) and ventricular arrhythmias (ventricular premature beats, ventricular tachycardia).

Can ventricular premature beats be cured by medication?
Can ventricular premature beats be cured by medication? The answer is no, medication cannot cure ventricular premature beats. However, with standardized medical treatment such as metoprolol and amiodarone, and maintaining good lifestyle habits, such as regular exercise, consistent sleep patterns, quitting smoking, limiting alcohol intake, and avoiding strong coffee and tea, the treatment effectiveness for ventricular premature beats is often quite good. Therefore, although medication cannot cure ventricular premature beats entirely, the treatment results can still be very positive, but it should always be conducted under the guidance of a doctor. (The use of medication should be under the guidance of a doctor)
How severe is an atrial septal defect considered to be?
Atrial septal defect (ASD) is a relatively common congenital heart disease in clinical practice. From a medical perspective, the severity of ASD depends on whether the patient is an adult or a child. For adults with ASD, generally speaking, defects larger than 20 millimeters are considered large atrial septal defects, which are more severe. If the defect size is between 10 and 20 millimeters, it is often classified as a moderate atrial septal defect. Defects smaller than 4 millimeters are considered small atrial septal defects. Generally, small and moderate atrial septal defects are not severe. For children, an atrial septal defect larger than 10 millimeters is considered a large atrial septal defect, which is more severe. Sizes between 5 and 10 millimeters are classified as moderate atrial septal defects. Defects smaller than 5 millimeters are considered small atrial septal defects, which generally are not severe.
Can myocarditis cause dizziness?
Cardiomyopathy is a fairly common disease in our daily lives. From a medical perspective, cardiomyopathy can usually be divided into dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular dysplasia, and restrictive cardiomyopathy. When cardiomyopathy is present for a long time, it may cause a decline in the heart’s pumping function, leading to a reduction in cardiac output and resulting in heart failure. In such cases, due to insufficient blood supply to the brain, patients often experience symptoms of dizziness. If diagnosed with cardiomyopathy, under the guidance of a doctor, regulated medication can often significantly improve symptoms, including dizziness. (Specific medication usage should be conducted under the guidance of a doctor; do not self-medicate.)
Clinical manifestations of dilated cardiomyopathy
The clinical manifestations of dilated cardiomyopathy can be summarized in two words: "three hearts," which are reflected in the following three aspects. First, heart enlargement, such as through chest X-rays or echocardiography, often reveals a notable enlargement of the patient's heart. Second, arrhythmias; dilated cardiomyopathy often accompanies a variety of arrhythmias, such as frequent ventricular premature beats, tachycardia, or atrial fibrillation. Third, heart failure. Dilated cardiomyopathy often results in symptoms of heart failure, such as exertional dyspnea and paroxysmal nocturnal dyspnea.
How many beats per minute is considered tachycardia?
Tachycardia refers to the phenomenon where the heartbeat exceeds 100 beats per minute. From a medical perspective, this can be classified into various types of tachycardia including sinus tachycardia, paroxysmal supraventricular tachycardia, ventricular tachycardia, among others. If one experiences such symptoms, it is crucial to visit a hospital for proper checks. An electrocardiogram (ECG) should be done to determine the specific type of tachycardia. Additionally, a complete blood count should be performed to check for anemia that might be causing tachycardia. Thyroid function tests including TSH, T3, and T4 should be conducted to rule out hyperthyroidism as a possible cause. Also, an echocardiogram should be done to check for any structural heart diseases that might lead to tachycardia.
Causes of infant room septal defect
Atrial septal defect is a relatively common congenital heart disease in infants and young children. The causes of atrial septal defects are not very clear, but modern medicine considers that it may be related to the mother having a cold during pregnancy or taking certain medications, or to certain physical and chemical factors during pregnancy. Generally, atrial septal defects are not inherited and are not largely related to genetics.
How to check for heart failure?
Heart failure is a relatively common cardiac disease in our daily lives, and patients often exhibit symptoms such as shortness of breath, difficulty breathing, and fatigue. So, how should heart failure be diagnosed? Generally, the following are common tests: First, an echocardiogram. An echocardiogram is a very practical and non-invasive test that can determine the presence of heart valve diseases, cardiomyopathy, and other conditions, as well as assess the heart's pumping function; Second, blood tests. For example, blood tests for electrolytes and BNP, or brain natriuretic peptide, can determine the presence of heart failure; Third, chest CT or X-rays. These can identify manifestations of pulmonary congestion caused by heart failure.
Does severe mitral valve regurgitation require surgery?
Severe mitral valve regurgitation requires surgical treatment, with options including mitral valve repair or replacement surgery. If left untreated, severe mitral regurgitation can lead to enlargement of the left ventricle and a reduction in the heart's ejection fraction, resulting in decreased pumping function and symptoms of heart failure. Patients may experience symptoms such as difficulty breathing, fatigue, and nocturnal paroxysmal dyspnea. Severe cases might even exhibit symptoms of acute left heart failure, such as orthopnea, profuse sweating, and coughing up pink frothy sputum. These symptoms typically necessitate hospitalization, which not only adds unnecessary financial burdens but also severely impacts the patient’s quality of life.
Arrhythmias include:
Arrhythmia is a very common disease in our daily life. What does arrhythmia include? Generally speaking, arrhythmia often includes the following aspects: First, irregular heartbeat, such as sinus arrhythmia, atrial fibrillation, and frequent premature beats. Second, tachycardia, such as paroxysmal supraventricular tachycardia, ventricular tachycardia, and so on. Third, bradycardia diseases, such as sinus bradycardia, severe atrioventricular block, and sick sinus syndrome, etc.
Management of poor heart condition and insomnia
If you have heart issues and are experiencing insomnia, you can consider the following adjustments: First, appropriate medication adjustments, such as under the guidance of traditional Chinese medicine, combining pulse-taking and tongue examination to determine the body's constitution, proper use of traditional Chinese herbs like sour jujube kernels, goji berries, poria, licorice, jujube, chrysanthemum, and honeysuckle to make porridge can to some extent improve sleep issues. Second, maintain good lifestyle habits, like keeping a positive mood, avoiding staying up late, developing the habit of sleeping regularly, and avoiding overeating, especially at dinner. If necessary, take Western medicine to improve sleep, such as eszopiclone, under the direction of a doctor.
