What is a cardiac arrhythmia? How does it affect the body?

Arrhythmias are a large group of cardiology disorders that include both tachyarrhythmias and bradyarrhythmias. Rapid arrhythmias include atrial fibrillation, atrial flutter, supraventricular tachycardia, premature ventricular tachycardia, ventricular tachycardia, etc. Patients may experience rapid heart rate, panic, irregular heartbeat, and feel that their heart is "beating randomly," which is often treated with medications and interventions. Slow arrhythmias include atrioventricular block, sinus arrest, sinus block, sinus bradycardia, etc. Patients usually experience a sudden slowing of the heartbeat, fainting without warning, dizziness, blackouts, and may fall to the ground, lose consciousness, and become incontinent.

What are the effects of arrhythmias on the body? Arrhythmias can be harmful to patients not only in terms of symptoms, but also in many ways. On the one hand, patients with atrial fibrillation are prone to thrombosis, which can cause cerebral embolism, limb embolism, and other circulatory embolism, and can have a serious impact on life. Cerebral embolism may also cause disability, which will cause serious burden to families and individuals. On the other hand, patients are hospitalized repeatedly because atrial fibrillation can produce effects on heart function, which can easily cause heart failure manifested by chest tightness and shortness of breath.

How should arrhythmias be treated? An attack of supraventricular tachycardia can be treated with physical stimulation, such as taking a deep breath, holding it, doing a Valsalva maneuver (taking a deep breath, closing the vocal cord tightly, and then doing a forceful exhalation), or pressing on the eyeballs to make it terminate the attack. If it does not terminate, you may need to go to the hospital for future radical treatment by radiofrequency ablation. Although aspirin does not prevent thrombosis in atrial fibrillation, patients with atrial fibrillation can have a CHSVASc score (stroke risk prediction score for patients with atrial fibrillation) under the supervision of a medical professional and use anticoagulants according to the CHSVASc score. Slow arrhythmias, on the other hand, can be fitted with a pacemaker.

Arrhythmias, as a large group of diseases, include many types of conditions. Each patient has his or her own different situation and each disease has its own characteristics, so patients are advised to visit a hospital for professional medical evaluation.
