Hello. You want to learn about short PR syndrome, symptoms and treatment, the doctor would like to provide some basic concepts to be able to explain to you specifically as follows: PR interval (PR interval), is time from the beginning of the P wave (atrial depolarization wave) to the beginning of the QRS wave (ventricular depolarization wave). This interval reflects conduction time across the atrioventricular node. The PR interval is measured on a surface electrocardiogram (12 leads) and can more accurately be measured during an electrophysiological study of the heart chambers (Electrophysiology Study). PR interval includes:
Normal PR interval is: 120 – 200 ms (from 3 to 5 small squares) So short PR interval is when PR interval < 120ms. The short PR interval suggests that there is some reason for this faster conduction. In practice, there are often two cases:
There is an accessory pathway from the atria to the ventricles (also known as accessory pathways). The beat is derived from the coupler (AV). Symptoms of a short PR interval mean that the patient will have symptoms of a tachycardia such as: rapid pulse, possibly accompanied by symptoms of hypotension or shock, etc. The tachycardia may stop spontaneously in time. Short or long lasting for hours, causing patients to feel tired, short of breath,...
The treatment of short PR interval will be decided depending on the pathology causing short PR interval, however, the intervention methods of ablation of sugar Radio frequency auxiliary is highly effective and very safe for patients. Currently, Vinmec Hospital has performed radiofrequency catheter ablation techniques for patients with arrhythmias. If you are interested, we will be happy to advise you more specifically, so you can come to the hospitals of Vinmec Health System nationwide for more advice.
