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).Voices
Manifestations of low blood pressure
Low blood pressure refers to a phenomenon where the systolic blood pressure is below 90mmHg and/or diastolic blood pressure is below 60mmHg. After developing low blood pressure, symptoms such as dizziness, palpitations, fatigue, and cold sweats often occur. If you have low blood pressure, it is essential to visit a hospital for proper examinations, such as a blood test to check for anemia. Conducting an echocardiography or an electrocardiogram can help determine if any heart diseases are causing the low blood pressure.
Is pericardial effusion related to pneumonia?
Pericardial effusion is generally not closely related to pneumonia. The common causes of pericardial effusion mainly include tuberculous pericarditis, as well as factors such as tumors, heart failure, and hypoproteinemia. The onset of pulmonary inflammation primarily affects the lungs, with symptoms often manifesting as cough and yellowish sputum. Some patients may also experience pleural effusion. Pulmonary CT scans typically show inflammatory exudative changes. If the pericardial effusion is minor, it is usually not a significant issue, but proper medical examination is necessary to rule out causes like tuberculosis or tumors that could lead to pericardial effusion.
Arteriosclerosis is a disease
Arteriosclerosis is a disease characterized by thickening of the arterial wall and narrowing of the arterial lumen due to plaque formation, leading to various problems. As for whether arteriosclerosis can be prevented and treated, the answer is definitely yes. This can be achieved by maintaining good lifestyle habits. Regular exercise, quitting smoking, and controlling blood pressure and blood sugar with medications under a doctor’s guidance, as well as appropriate use of statin medications, can effectively prevent and treat the onset, progression, and worsening of arteriosclerosis.
Does sudden cardiac death have a relationship with hypertension?
Sudden cardiac death and hypertension are related, with the most common cause of sudden cardiac death being acute myocardial infarction, which leads to malignant arrhythmias, such as ventricular fibrillation, resulting in sudden cardiac death. In addition, severe aortic dissection can also cause sudden cardiac death, and hypertension is often an important cause of coronary heart disease, acute myocardial infarction, and aortic dissection. Long-term hypertension can lead to the occurrence of arteriosclerosis, resulting in the formation of arterial plaques or aneurysms, such as those occurring in the coronary arteries, causing coronary heart disease and myocardial infarction, or in the aorta, often leading to the formation of aortic aneurysms. When an aortic aneurysm ruptures, it can cause aortic dissection.
Can pericardial effusion cause chest pain?
Pericardial effusion can cause chest pain because patients with pericardial effusion have limited cardiac diastolic expansion, resulting in a restricted blood volume during the cardiac diastolic phase. This ultimately causes reduced cardiac pumping, leading to symptoms of ischemia and hypoxia, such as chest tightness or chest pain. Furthermore, as the amount of pericardial effusion decreases, for example from moderate or large volumes to a small amount, chest pain symptoms can also occur. This is because when the volume of pericardial effusion significantly reduces, there can often be friction between the visceral and parietal layers of the pericardium, thereby triggering chest pain. This condition is often accompanied by a pericardial friction rub, which can be felt by touching the precordial area.
Is dilated cardiomyopathy more serious or is myocardial ischemia more serious?
This has to be judged comprehensively based on the following conditions: First, the age factor. If it occurs in young people, dilated cardiomyopathy tends to be more severe. This is because dilated cardiomyopathy is an organic heart disease, and myocardial ischemia in young people may not necessarily involve organic heart disease changes, but could also be normal physiological changes in the electrocardiogram. Second, whether there is concurrent cardiac function impairment. Dilated cardiomyopathy definitely involves impairment of the heart's pumping function, whereas myocardial ischemia does not necessarily involve such impairment. Therefore, in most cases, dilated cardiomyopathy is more serious.
How to prevent arteriosclerosis
Atherosclerosis is a disease related to aging, poor lifestyle habits such as smoking, and metabolic abnormalities such as hyperlipidemia or diabetes. Atherosclerosis can be effectively prevented. To prevent atherosclerosis, the following should be adhered to: First, maintain good lifestyle habits, exercise regularly, quit smoking, limit alcohol consumption, and eat less spicy and greasy foods. Second, control blood pressure, blood lipids, and blood sugar levels. When issues such as elevated blood pressure and lipids arise, it is necessary to use medication under the guidance of a doctor.
Complications of heart disease
Heart disease is a very common illness in our daily lives. What are the complications of heart disease? The category of heart diseases is broad; here we will discuss some common ones, such as coronary heart disease. Patients with coronary heart disease are prone to develop heart failure, leading to symptoms such as shortness of breath and difficulty breathing, or atrial fibrillation. Atrial fibrillation often leads to complications like thrombosis. For instance, a dislodged thrombus can cause a cerebral infarction, resulting in symptoms like hemiplegia, weakness in one side of the body, and speech disturbances. Additionally, certain severe myocardial diseases can lead to malignant arrhythmias, causing sudden death in patients, which is often very serious.
What should I do if dilated cardiomyopathy is causing insomnia?
Dilated cardiomyopathy causing insomnia needs to be treated based on the cause of the insomnia. First, if it is simply poor sleep quality causing occasional insomnia, no special treatment is needed. However, if insomnia occurs daily and affects quality of life, sleep-improving medications such as eszopiclone or zopiclone may be taken under a doctor's guidance. Second, if caused by worsening heart failure symptoms, which lead to nocturnal respiratory distress and affect sleep, resulting in insomnia, the treatment for heart failure should be intensified under a doctor's guidance, for instance, by increasing diuretic treatment or adjusting medications. Improving heart failure symptoms naturally enhances sleep quality. (If medication is required, please do so under the guidance of a doctor)
Is it called hypertension if the diastolic blood pressure is high?
High diastolic pressure, which is an increase in diastolic pressure, is also considered hypertension when the diastolic pressure exceeds 90mmHg. If you have hypertension, it is essential to have a formal medical examination at a hospital, such as blood tests for lipids and glucose to check for diabetes and hyperlipidemia. Blood tests are also done to evaluate liver and kidney functions, to see if there are any kidney diseases causing the increase in blood pressure. Additionally, under the guidance of a doctor, conduct ambulatory blood pressure monitoring to observe the overall situation of blood pressure increase within 24 hours. Based on the results of the blood tests and ambulatory blood pressure monitoring, determine whether antihypertensive medication is needed and which type of medication to use.
