Randomized Controlled TrialNifekalant hydrochloride terminating sustained ventricular tachycardia accompanied with QT dispersion prolongation.
Ventricular tachycardia (VT) and ventricular fibrillation are the main reasons causing sudden cardiac death. This study aimed to investigate the effects of nifekalant hydrochloride (NIF) on QT dispersion (QTd) in treating VT. ⋯ More administration of NIF indicates higher terminating rate of VT and more QTd prolongation. However, the safety is acceptable if several important issues were noticed in using NIF, such as serum potassium concentration, stopping side-effect related agents, and carefully observing clinical responses.

Endobronchial ultrasound-guided transbronchial needle aspiration of undiagnosed mediastinal lymphadenopathy.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can sample the enlarged mediastinal lymph nodes which are unreachable by conventional bronchoscopy. It is a relatively simple and safe method to see beyond the bronchial tree. We describe and discuss its initial application and our experience. ⋯ EBUS-TBNA can provide a safe and effective method to sample mediastinal leisions suspected of malignancy. It also adds pathological information needed to make the diagnosis of sarcoidosis.
