摘要: A dual chamber heart pacemaker has atrial and ventricular pulse generators (21, 22) sense amplifiers (25, 26) which connect respectively to an terminal (11) a (12) for connection the (10). In synchronous mode, provides stimulating pulses in response detected spontaneous contractions, spaced from them by A-V interval determined timer (31). atrial-ventricular sequential (40) causes deliver stimulation are separated time another (30). The atrialventricular intervals mode independent of each other, permitting selection different two modes operation.
