Answer:
Hello! The short PR interval is also known as Lown-Ganong-Levine (LGL) syndrome, which refers to a short PR interval on an electrocardiogram (ECG), followed by a normal QRS complex (without a delta wave) in combination with a history of paroxysmal tachycardia. Treatment may include parasympathetic maneuvers: carotid sinus massage, Valsalva maneuver, gag reflex, etc. If these are ineffective, medication must be used. Intravenous antiarrhythmic drugs are the chosen treatment, one of the following: Class Ic (ajmaline, propafenone, flecainide) or Class Ia (procainamide, disopyramide, quinidine). If the tachycardia cannot be solved, cardioversion with an initial dose of 50J is necessary. During an episode of tachycardia, the patient may faint, and if atrial fibrillation with rapid ventricular response leads to ventricular fibrillation, the patient may have sudden death.
Through the doctor's answers, you can understand how short PR interval is treated and whether the disease is dangerous.
