arrhythmia
What tests are done for arrhythmia?
Arrhythmia is also relatively common in clinical practice, and its common detection method is mainly the electrocardiogram (ECG). ECG is a simple and non-invasive operation that helps to identify the type of arrhythmia. Another method is the 24-hour Holter monitor, which can record all heart rate changes occurring within 24 hours. If an arrhythmia occurs, it is crucial to seek medical attention promptly, visiting a cardiology department. Treatment may involve antiarrhythmic medications, and if possible, a complete electrophysiological examination can be performed.
What is ventricular arrhythmia?
Ventricular arrhythmias mainly refer to disorders of the ventricular rhythm and are relatively common clinically, including premature ventricular contractions, ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Premature ventricular contractions generally do not cause noticeable clinical symptoms, while ventricular flutter and ventricular fibrillation are very dangerous clinically and must be treated promptly with defibrillation. Therefore, ventricular arrhythmias must be treated promptly, actively treating the underlying disease, and managing the arrhythmia to prevent sudden death.
Ventricular arrhythmias include the following types.
Common ventricular arrhythmias mainly include premature ventricular contractions, ventricular tachycardia, ventricular flutter, and ventricular fibrillation. Premature ventricular contractions appear on the electrocardiogram as prematurely occurring wide and abnormal QRS complexes. If asymptomatic, no treatment is needed; if symptomatic, receptor blockers can be used for treatment. Ventricular tachycardia is clearly indicated on the electrocardiogram by wide and abnormal QRS complexes, with heart rates ranging from 140 bpm to 200 bpm. The primary treatment is to remove the cause, and electrical cardioversion can be used when hemodynamics are unstable. Ventricular flutter and fibrillation, their ventricular rates are generally above 250 bpm, and treatment is crucial.
Is arrhythmia very harmful?
Firstly, arrhythmias, whether supraventricular or ventricular, are harmful to the human body. However, ventricular arrhythmias tend to be more damaging. Supraventricular arrhythmias, including supraventricular tachycardia and atrial tachycardia, generally have a minimal impact on hemodynamics. However, they may still cause symptoms in patients such as palpitations, chest tightness, or even fatigue, a series of discomforting symptoms, but generally do not pose a life-threatening risk. However, ventricular arrhythmias are different, as they can cause disturbances in the body's hemodynamics, leading to ischemia and failure of various organs. Therefore, the harm they cause is significant, and they may even lead to sudden cardiac death. Hence, aggressive treatment and management of ventricular arrhythmias are necessary.
Can arrhythmia be cured?
Arrhythmias come in many types, most of which are curable. Once arrhythmia occurs clinically, an electrocardiogram should be performed as soon as possible to determine the type of arrhythmia. Common arrhythmias can be classified into tachyarrhythmias and bradyarrhythmias, and based on the location of occurrence, into supraventricular arrhythmias and ventricular arrhythmias. Clinically common are supraventricular arrhythmias, such as sinus tachycardia, junctional tachycardia, along with atrial tachycardia, atrial fibrillation, and atrial flutter. These generally do not affect the stability of hemodynamics and are relatively easy to treat. On the other hand, ventricular arrhythmias such as ventricular fibrillation, ventricular tachycardia, and sinus arrest are clinically challenging to cure and require aggressive resuscitation.
What should be paid attention to in daily life with arrhythmia?
For managing arrhythmias, it's important to pay attention to several aspects. First, maintain a regular lifestyle and ensure adequate sleep. Second, the living environment should be quiet and serene to avoid noise, and it’s beneficial to grow various plants for a better temperament. Third, balance work and rest according to personal capacities and engage in appropriate physical activities such as walking, Tai Chi, and Qigong; moderate sexual activities and avoid colds. Fourth, strive to maintain a standard weight and not indulge in overeating, as obesity can increase cardiac load. Fifth, be mindful of changes in seasons, weather, and climate, as extreme cold or hot conditions can significantly impact the disease, potentially aggravating or triggering arrhythmias. Sixth, diet should be light with frequent, small meals, and avoid coffee, strong alcohol, fried foods, and minimise strong tea. Seventh, keep a stable emotional state and try to eliminate stress, fear, anxiety, irritation, and anger which are stimulants that could negatively affect your emotions. Eighth, in addition to daily medications, have emergency medications prescribed by a doctor on hand, such as Xintiandan, Shexiang Baoxin Pill, Xintongding, Atropine, etc. Ninth, if there are sudden exacerbations of arrhythmia accompanied by palpitations, chest tightness, dizziness, low blood pressure, and sweating, and in severe cases fainting, seek medical attention promptly.
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.
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.
