Arrhythmia is very common in clinical settings, and its treatment mainly includes etiological treatment and symptomatic treatment. If a patient experiences occasional premature beats without significant hemodynamic effects, special treatment may not be necessary at this time. However, if a patient repeatedly experiences supraventricular tachycardia, atrial fibrillation, and other arrhythmias, cardiac electrophysiological examination and dynamic heart rate monitoring should be conducted. Antiarrhythmic drugs or even radiofrequency ablation may be administered for symptomatic treatment, as uncontrolled arrhythmias can easily lead to sudden death in patients.

What tests are done for arrhythmia?

The examinations required for arrhythmia are as follows: First, an electrocardiogram, which is the most important non-invasive diagnostic technique for diagnosing arrhythmias. Second, a Holter monitor test should be conducted, which records the electrocardiogram continuously over 24 hours to possibly capture the occurrence of symptoms such as palpitations and fainting, and whether they are related to arrhythmias. It clarifies the relationship between arrhythmias or myocardial ischemia attacks and daily activities, as well as their diurnal distribution characteristics, and can assist in evaluating the efficacy of medications and the condition of pacemakers to some extent. Third is the exercise test; if palpitations occur during exercise, an exercise test can assist in making a diagnosis. Fourth is the esophageal electrocardiogram, which is a useful non-invasive method for diagnosing arrhythmias. Fifth is the cardiac electrophysiological study, typically involving the placement of electrode catheters on the upper and lower parts of the right atrial wall, the tip of the right ventricle, the coronary sinus, and the His bundle area, with the electrical activity at these sites being simultaneously recorded using a multi-channel physiological recorder with 8-12 channels or more.

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.

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.

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.

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.
