Sinus arrhythmia, the most common cause of which is instability of the nerves that regulate the heart, referred to as the autonomic nervous system. This instability leads to sinus arrhythmia, which is commonly seen in children during their growth phase, women during menopause, or individuals who often stay up late and are under significant work stress, leading to dysfunction of the autonomic nervous system. It can also be caused by patterns of breathing that lead to arrhythmias; the heart rate increases during inhalation and slows during exhalation, producing this type of physiological arrhythmia. Generally, this kind of arrhythmia does not require drug treatment. By improving physical exercise, ensuring adequate sleep, and avoiding stimulating beverages or coffee, this type of heart rate can return to normal.

Arrhythmias include:

Arrhythmia is a very common disease in our daily life. What does arrhythmia include? Generally speaking, arrhythmia often includes the following aspects: First, irregular heartbeat, such as sinus arrhythmia, atrial fibrillation, and frequent premature beats. Second, tachycardia, such as paroxysmal supraventricular tachycardia, ventricular tachycardia, and so on. Third, bradycardia diseases, such as sinus bradycardia, severe atrioventricular block, and sick sinus syndrome, etc.

Does arrhythmia require hospitalization?

Arrhythmia treatment should be determined based on the patient's symptoms, type of arrhythmia, and its impact on hemodynamics. For instance, minor conditions like slight sinus bradycardia, irregular sinus rhythm, occasional atrial premature contractions, and first-degree atrioventricular block, which have minimal impact on hemodynamics and no significant clinical manifestation or structural heart disease, do not necessitate hospitalization. However, more severe arrhythmias such as sick sinus syndrome, rapid atrial fibrillation, paroxysmal supraventricular tachycardia, and sustained ventricular tachycardia, which can cause symptoms like palpitations, chest tightness, dizziness, low blood pressure, sweating, and in severe cases, fainting, Adam-Stokes syndrome, and even sudden cardiac death, require prompt medical attention and hospitalization for treatment.

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.

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 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.
