Context

Country: Canada
State/Province: Ontario
Period: late 1960s
Canada: 1st pacemaker developed at NRC in 1950 by John Hopps was approx. 30cm long and several cm high & wide. Development of transistors & reliable batteries permitted design of pacemaker of implantable size (1957). Pacemaker regarded as one of greatest Canadian engineering achievements of the 20th century. (Ref. 2)
Function: Experimental pacemakers used to study the threshold of pacing, non- implantable because researchers needed access to the controls to vary the speed.
Technical: More sophisticated version of round pacemakers 850601. Prototype variable speed pacemakers for laboratory use to study the threshold of heart pacing, waveform studies and pulse widths.
Area Notes: Unknown
