A new type pacemaker with multifunctional pacing modes that can be used for temporary intra- or extra- single/dual chamber cardiac pacing is described. A LCD screen is integrated in this portable device to provide a real time electrocardiograph (ECG) monitoring. This device displays intra-chamber ECG that could guide physician to catheterize the heart without X-ray machine/fluoroscopy or other guiding equipment. It also can be used as an independent long-term surface ECG monitor. This device was built for the purposes of cost-effectiveness, safety, reliability and user friendliness. It is equipped with a clear-cut circuit design, a unique three level switching system for managing electrophysiological stimulation, interface of person/machine dialog, and cardiac signal recording. This multifunctional apparatus designed for multipurpose of clinical diagnosis and treatment fulfills and extends the clinical utilities of temporary cardiac pacing.
