arrhythmia
What department should I go to for arrhythmia?
Arrhythmia is generally treated in the department of cardiovascular medicine. What is arrhythmia? It mainly refers to abnormalities in the frequency, rhythm, origin, conduction speed, or excitation sequence of the heart's impulses. Based on the principles of arrhythmia occurrences, it can be divided into two major categories: abnormalities in impulse formation and abnormalities in impulse conduction. Abnormalities in impulse formation include sinus arrhythmias and ectopic rhythms, while abnormalities in impulse conduction include interference atrioventricular dissociation, sinoatrial conduction block, intra-atrial conduction block, atrioventricular conduction block, and bundle branch block, among others.
Is ventricular arrhythmia serious?
Arrhythmias are primarily divided into sinus arrhythmias, atrial arrhythmias, and ventricular arrhythmias. Among these, ventricular arrhythmias are further categorized into ventricular premature contractions, ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Ventricular flutter and ventricular fibrillation are fatal types of arrhythmias. Patients generally experience loss of consciousness, generalized convulsions, and even cessation of breathing and death. If ventricular fibrillation occurs, it is imperative to immediately perform defibrillation and cardiopulmonary resuscitation, among other emergency interventions.
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.
What department should one go to for arrhythmia?
Arrhythmia is an important group of diseases among cardiovascular diseases. It can occur on its own or in conjunction with other cardiovascular diseases, thus it mainly requires consulting a department of cardiology. However, due to other causes such as electrolyte or endocrine disorders, anesthesia, hypothermia, thoracic or cardiac surgery, drug effects, and central nervous system diseases, the assistance of endocrinologists and neurologists is needed for diagnosis and treatment. Sometimes, the arrhythmia might be caused by endocrine disorders, such as thyroid diseases or hypoglycemic symptoms in diabetes, necessitating a consultation with the department of endocrinology. If symptoms like transient blindness, fainting, dizziness, or convulsions occur, it is essential to consider brain-related diseases, such as epilepsy or transient insufficient brain blood supply, and consult the department of neurology to make a differential diagnosis.
Arrhythmia is what kind of disease
Arrhythmia is caused by abnormal excitation of the sinoatrial node or excitation originating outside the sinoatrial node, where the propagation of excitation is slow, blocked, or conducted through abnormal channels, leading to abnormalities in the frequency and/or rhythm of heartbeats due to origins and (or) conduction disorders of cardiac activity. Arrhythmia is an important group of diseases within cardiovascular diseases. It can occur independently or in conjunction with other cardiovascular diseases. Its prognosis is related to the causes, inducing factors, and evolutionary trends of the arrhythmia, and whether it leads to severe hemodynamic disturbances. It can cause sudden death or continuously affect the heart leading to its failure.
Do arrhythmias need treatment?
The treatment of arrhythmias should be based on the symptoms of the patient, the type of arrhythmia, and its impact on hemodynamics to determine if treatment is necessary. For instance, mild sinus bradycardia, irregular sinus rhythm, occasional atrial premature contractions, and first-degree atrioventricular block have minimal impact on hemodynamics. Therefore, if there are no obvious clinical symptoms and no cardiac structural disease, temporary drug treatment may not be required. However, severe arrhythmias such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and persistent ventricular tachycardia can cause palpitations, chest tightness, dizziness, low blood pressure, severe sweating, and in severe cases, syncope, Adams-Stokes syndrome, or even sudden death, which require immediate medical attention.
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.
