Sinus arrhythmia
"Dou xing xin lv shi chang" translates to "sinus rhythm disorder" in English.
Sinus arrhythmia, including sinus tachycardia, sinus bradycardia, and sinus arrhythmia, is first and foremost a normal source of heart rate, that is, sinus rhythm. Based on this, its frequency is somewhat abnormal, and we differentiate it into sinus tachycardia or sinus bradycardia. There are cases where, although the frequency is between 60-100 beats per minute, the rhythm is irregular, which we refer to as sinus arrhythmia. So, sinus arrhythmia generally refers to these three conditions. In terms of management, sinus tachycardia often has a specific cause that needs correction. Sinus bradycardia, in some cases, leads to symptoms of insufficient cardiac output, such as fainting, which may require the installation of a pacemaker. Sinus arrhythmia usually does not require special treatment.
What medicine to buy for arrhythmia?
Arrhythmia encompasses a large category of diseases, including sinus tachycardia, bradycardia, sick sinus syndrome, as well as atrial fibrillation, flutter, premature atrial contractions, supraventricular tachycardia, premature ventricular contractions, and atrioventricular block, among others. Due to the various types of arrhythmias, the medications used also differ. It is necessary to go to a hospital for a clear diagnosis to determine the specific type of arrhythmia before using appropriate anti-arrhythmic drugs. Some arrhythmias cannot be resolved just by medication; for instance, in cases like pacemaker syndrome, a pacemaker needs to be installed. Additionally, patients with atrial fibrillation who have tachy-brady syndrome also require a pacemaker. Therefore, the decision on what medication to purchase for arrhythmia should be made by a doctor.
How to treat arrhythmia?
The treatment of arrhythmias should be based on the symptoms of the patients with arrhythmias, the type of arrhythmias, and their impact on hemodynamics. Control of arrhythmias during episodes involves removing the cause and focus of the disease and preventing recurrence, which can be divided into non-pharmacological and pharmacological treatments. Non-pharmacological treatments include methods such as eyeball compression, carotid sinus massage, pinching the nose to exhale forcefully and hold breath to reflexively excite the vagus nerve, along with electrical treatments like electrical cardioversion, defibrillation, pacemaker implantation, and ablation surgery. There are mainly four types of drugs used: sodium channel blockers; beta-adrenergic blockers; drugs selectively prolonging the repolarization process, such as amiodarone; and calcium channel blockers. However, long-term use of these antiarrhythmic drugs can have varying degrees of side effects, and severe cases can cause ventricular arrhythmias or cardiac conduction block which can be fatal. Therefore, in clinical application, it is essential to strictly control the indications, monitor for adverse reactions, and rigorously follow the doctor's orders.
Causes of arrhythmia
Arrhythmia is a common and frequently occurring disease in clinical practice, primarily caused by various organic heart diseases. Common heart diseases include coronary heart disease, congenital heart disease, rheumatic heart disease, pulmonary heart disease, severe myocarditis, and cardiomyopathy, all of which can lead to arrhythmias that are generally severe. Arrhythmias can also occur in some healthy individuals due to instability of the autonomic nervous system. This type of arrhythmia can be clinically cured through lifestyle adjustments, appropriate exercise, and improvements in myocardial contractility and conductivity.
Arrhythmia refers to what?
Arrhythmia refers to the abnormal origination or conduction of impulses in the heart due to abnormal activation of the sinoatrial node, slow conduction, blockages, or passage through abnormal pathways, leading to abnormalities in the frequency and/or rhythm of the heartbeat. Arrhythmias are a significant group of cardiovascular diseases. They can occur alone or in conjunction with other cardiovascular diseases. The prognosis of arrhythmias depends on their causes, triggers, trends in progression, and whether they lead to severe hemodynamic disturbances, potentially causing sudden death or continuous impairment of heart function leading to heart failure.
Does arrhythmia cause nausea?
Mild arrhythmias, such as sinus bradycardia, sinus arrhythmia, occasional atrial premature contractions, and first-degree atrioventricular block, have minimal impact on hemodynamics, so they generally do not show obvious clinical symptoms. In cases of severe arrhythmias, such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and sustained ventricular tachycardia, significant arrhythmias affect hemodynamics, reduce blood flow, and cause mesenteric artery spasm, which can lead to clinical manifestations of gastrointestinal ischemia, such as nausea, and even bleeding, ulcers, or paralysis.
Symptoms of Sinus Arrhythmia
Symptoms of sinus arrhythmia vary according to different causes, including sinus bradycardia, sinus tachycardia, sinus arrhythmia, sinus arrest, and sick sinus syndrome. Mild cases of sinus bradycardia, sinus tachycardia, and arrhythmia generally do not present noticeable clinical symptoms. However, severe cases can experience symptoms such as palpitations, fatigue, and shortness of breath. Sinus arrest and sick sinus syndrome often present more severe clinical symptoms, including not only shortness of breath but also dizziness, blackouts, fainting, and acute cerebral ischemia and hypoxia.
Why does arrhythmia cause chest pain?
The causes of chest pain due to arrhythmias primarily involve all kinds of arrhythmias reducing the blood flow in the coronary arteries. Although various arrhythmias can decrease coronary blood flow, they rarely cause myocardial ischemia. However, severe arrhythmias that cause significant myocardial ischemia can result in chest pain. For patients with coronary heart disease, various arrhythmias can induce or exacerbate myocardial ischemia, which may also manifest as chest pain and shortness of breath, and in severe cases, lead to acute heart failure, acute myocardial infarction, and persistent, unbearable chest pain and tightness.
Is sinus arrhythmia serious?
Sinus arrhythmia is a relatively common type of arrhythmia in clinical practice. It is typically identified through electrocardiogram testing. If no other specific symptoms are present other than sinus arrhythmia, sinus bradycardia, or sinus tachycardia, and if there is no structural heart disease, generally, there are no serious concerns. Often, these kinds of arrhythmias are caused by autonomic nervous system dysfunction, leading to an imbalance between the sympathetic and parasympathetic nerves. To address this irregular heartbeat, it is advisable to rest adequately in daily life and to include some aerobic exercise. Exercise can enhance cardiac contractility and strengthen regular heart function, which can help correct the arrhythmia.
Arrhythmia is what?
Arrhythmia refers to abnormalities in the frequency, rhythm, origin, or conduction of the heartbeats. It can occur in healthy individuals as well as those with related diseases, and may involve cardiac diseases or other medical conditions. The primary mechanism behind the occurrence of arrhythmias is the abnormal formation of cardiac impulses or the abnormal conduction of these impulses. It is important to actively seek the causes of arrhythmias and control the factors that trigger them. For diseases associated with arrhythmias, proactive management is necessary. When severe arrhythmias occur, timely and effective treatment is crucial to prevent adverse outcomes.
