Leveraging three decades of cardiac pacing expertise, the PACE 203H epitomizes the contemporary standard in temporary pacing technology and stands as Oscor's third-generation series of dual-chamber external cardiac pacemakers. Meanwhile, the PACE 101H distinguishes itself with its lightweight design, user-friendly operation, robustness, and reliability. Tailored for temporary atrial or ventricular pacing, it supports both synchronous (VVI, AAI) and asynchronous (VOO, AOO) operating modes.
