[Clinical study on the treatment of premature ejaculation with Nailifu Spray].

Objective: To observe the effect of Nailifu Spray on the treatment of premature ejaculation.

Methods: A total of 90 patients were included in this study from January 1, 2022 to January 1, 2023. Nailifu spray was used to spray the surface of penile skin once a day, 2 sprays per session for 4 weeks.

Idiopathic premature ventricular contractions and ventricular tachycardias originating from the vicinity of tricuspid annulus: results of radiofrequency catheter ablation in thirty-five patients.

Background: In recent years, catheter ablation has increasingly been used for ablation of idiopathic premature ventricular complexes (PVCs) or ventricular tachycardias (IVTs). However, the mapping and catheter ablation of the arrhythmias originating from the vicinity of tricuspid annulus (TA) may not be fully understood. This study aimed to investigate electrophysiologic characteristics and effects of radiofrequency catheter ablation (RFCA) for patients with symptomatic PVCs and IVTs originating from the vicinity of TA.
