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.

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.

Can people with arrhythmia eat ginseng?

Arrhythmia falls under the categories of palpitations and throbbing in traditional Chinese medicine. The common differential diagnoses are as follows: For Blood Stasis Obstruction type, the treatment focuses on activating blood circulation and resolving stasis, and regulating qi to unblock the collaterals. For Blood Deficiency type, the treatment is to nourish qi and calm the spirit, and to nourish the heart and supplement blood. For Yang Deficiency type, the treatment aims to warm and supplement heart yang, and calm the spirit and stabilize the will. For Heart Deficiency and Timid Gallbladder type, the treatment is to nourish the heart and calm the spirit, and to stabilize fright and fix the will. For Yin Deficiency and Exuberant Fire type, the treatment focuses on nourishing the heart and calming the spirit, and nourishing yin to clear the fire. For Water Dampness Overwhelming the Heart type, the treatment aims to invigorate heart yang and transform qi to promote water movement. For Qi and Blood Deficiency type, the treatment is to supplement both qi and blood simultaneously. Ginseng's main therapeutic effect is to greatly supplement the primal qi, secure and stop prolapse, generate fluids, and calm the spirit. Therefore, ginseng can be used when arrhythmia differentiation indicates qi deficiency, but it is recommended to use it under the guidance of a traditional Chinese medicine practitioner.

Can arrhythmia cause sudden death?

The clinical manifestations of hemodynamic changes caused by arrhythmias mainly depend on the nature, type, cardiac function, and the extent of impact on hemodynamics. Mild conditions such as slight sinus bradycardia, sinus arrhythmia, occasional atrial premature contractions, and first-degree atrioventricular block have minimal impact on hemodynamics and therefore do not exhibit significant clinical manifestations, and sudden death is generally not expected. However, more severe arrhythmias, such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and sustained ventricular tachycardia, can lead to palpitations, chest tightness, dizziness, hypotension, and sweating. In severe cases, syncope, Adams-Stokes syndrome, or even sudden death may occur.

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.

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.
