Symptoms of paroxysmal arrhythmia, these characteristics should be known

A very common type of arrhythmia is paroxysmal arrhythmia. The typical symptoms exhibited by patients are palpitations, dizziness, sweating, and chest tightness. An electrocardiogram should be performed in time to confirm the diagnosis. In normal times, more attention should be paid to the scientific diet for arrhythmia to avoid the onset of the disease.

1. Paroxysmal supraventricular tachyarrhythmia (PSVT) is a common arrhythmia, which includes various types of tachycardia and causes a series of clinical manifestations due to the sudden and rapid acceleration of the patient's heartbeat. Patients with paroxysmal supraventricular arrhythmias often experience palpitations, sweating, dizziness, vertigo, chest tightness, chest pain and difficulty breathing during an attack, and fewer patients may experience syncope.

2. Paroxysmal supraventricular arrhythmias include many types. Patients with irregular heart rhythm mostly suffer from premature contractions, atrial fibrillation, and multifocal atrial tachycardia; while paroxysmal supraventricular tachycardia is characterized by absolutely regular heart rhythm, repeated attacks of arrhythmia, and sudden onset and cessation of arrhythmia. Stimulation of the vagus nerve can terminate reentrant tachycardias involving the sinoatrial node, such as atrioventricular reentrant tachycardia and atrioventricular nodal reentrant tachycardia.

3. The definitive diagnosis of paroxysmal supraventricular arrhythmia mainly relies on electrocardiogram examination. Generally, the type of arrhythmia of the patient can be diagnosed by recording a normal twelve-lead electrocardiogram. Through careful analysis of the electrocardiogram, an experienced cardiologist can also determine the approximate location of impulse reentry in the patient's heart and make a rough judgment on the location for future radiofrequency ablation surgery.

4. Patients with infrequent paroxysmal supraventricular arrhythmias can use dynamic electrocardiogram or event recorder to capture abnormal heart rhythm. Invasive electrophysiological examination is generally used to diagnose and treat patients with a history of paroxysmal regular palpitations.
