Given the document below, determine if the summary is factually consistent with the document. A summary is factually consistent if all the pronouns in the summary are presented the same way as in the document and they do not introduce any ambiguity.

Document: Scientists turned heart cells into pacemaker cells by injecting a gene. The "biological pacemaker" was able to "effectively cure a disease", said scientists from the Cedars-Sinai Heart Institute in Los Angeles. The British Heart Foundation said applications of the research, published in Science Translational Medicine, were "a long way off". The researchers injected a gene into pigs with a heart condition that causes a very slow heart rate. The gene therapy converted some of the billions of ordinary heart muscle cells into much rarer specialised cells that kept the heart beating in rhythm. The patch of cells the size of a peppercorn had acted as a pacemaker for two weeks, taking over the function of a conventional pacemaker, said the US team. "We have been able, for the first time, to create a biological pacemaker using minimally invasive methods and to show that the biological pacemaker supports the demands of

Summary: 1. Heart rate Conventional pacemakers are electronic devices that are implanted in the chest to control abnormal heartbeats.
