Cardiac neurosis itself does not usually cause supraventricular tachycardia (supraventricular tachycardia), but it may induce paroxysmal supraventricular tachycardia if a cardiac neurosis episode causes a sustained increase in the heart rate. Cardiac neurosis generally means that the patient often has discomfort in the precordial area, palpitations, chest tightness, shortness of breath, etc., but any tests done are basically normal and do not reveal any organic heart disease, often due to factors such as anxiety, stress, and psychological trauma. It does not usually cause supraventricular tachycardia. Supraventricular tachycardia is generally referred to as supraventricular tachycardia and is a common clinical arrhythmia. If the patient has a cardiac neurosis, when anxiety and stress may lead to a neurosis attack, the neurosis may lead to an increase in heart rate, and when the sinus tachycardia reaches a certain level, the sinus rhythm may become supraventricular, which in turn may induce paroxysmal supraventricular tachycardia. If supraventricular tachycardia occurs, it is recommended that the patient should go to the hospital in a timely manner to improve the relevant examinations to rule out whether it is caused by physiological factors, and whether it is necessary to be treated by a professional doctor.
