Jonas Kabschmode. The usual stimulation waveforms are either monophasic or biphasic. Charge imbalance occurs by semiconductor failure. Such imbalance may also arise from leakage currents. The main cause is cross talk between adjacent stimulating channels (sites) as well as cable failure. Positive charge balance跑过 发表于 2025-3-25 13:19:53
Jonas Kabsch the electrogram. They were brainless devices which only paced the ventricles asynchronously. Subsequent advanced devices called demand mode pacemakers contained a sense amplifier. This amplifier measured the cardiac activity of the patient to evade competition of the actual rhythms of the heart wit怎样才咆哮 发表于 2025-3-25 17:52:42
Jonas Kabsch a clock signal. A clock generator IC can perform various functions. The functions include the generation, conditioning, manipulation, distribution, or control of a timing signal in an electronic system. The output of clock generators is toggling on/off constantly. To build clock generator circuits,AUGUR 发表于 2025-3-25 20:22:52

Jonas Kabschns. Then, other methods for active charge balancing are resorted to. A stimulator circuit that is foolproof without off-chip blocking capacitors produces an active stimulation phase by high-frequency current switching. This phase is followed by a succeeding passive discharge phase.noxious 发表于 2025-3-26 17:31:28
Jonas Kabsch one lead per ventricle. Another noteworthy feature is that the early devices were an assembly of discrete resistors, transistors, and capacitors wired together on printed circuit boards, whereas the new devices are highly complex and integrated microprocessor-based systems. They are essentially ext
