从1973至1987年132例病人置入155只由放射性同位素供能的起搏器。最早置入的15只核能起搏器均为 VOO 型,它们的寿命显著长于15只由锂化学电池供能的按需型(VVI型)起搏器(P=0.0002)。155只核能起
From 1973 to 1987, 132 patients had 155 pacemakers powered by radioisotopes. The first 15 nuclear pacemakers were VOO-type, and their lifetimes were significantly longer than 15 on-demand (VVI) pacemakers powered by lithium chemistry cells (P = 0.0002). 155 nuclear can start
