Short P-R syndrome it is manifested on the electrocardiogram as a shortened P-R interval of less than 0.12 seconds, without δ-wave QRS graphic ECG manifestations, which can be accompanied by paroxysmal supraventricular tachycardia, atrial flutter, atrial fibrillation with rapid arrhythmias, so it is called short P-R syndrome. For this condition it does have certain hazards, the main one being arrhythmias. For example, some fast heart rate arrhythmias can often cause dizziness, palpitations, chest tightness, and other such conditions. Some heart rates are faster than 200 beats per minute. Some patients will also experience dizziness and cerebral ischemia, so the danger is still relatively great. For the treatment of this short P-R syndrome, at present, if there is a pre-excitation syndrome with rapid arrhythmia, radiofrequency ablation is the first choice. If the attack is hemodynamically unstable, this situation should be electrically resuscitated or use drugs to first turn back, and then fundamentally to treat or choose radiofrequency ablation to treat.
