Telemetry is really nothing new. Telemetric cardiac monitoring was invented in 1949 by Norman J Holter. Its clinical use started in the early 1960s, with traditional telemetry typically requiring surgery, which made it an invasive procedure. The surgery would include all the usual suspects, such as anesthesia, the implantation of a transmitter, and the presence of a medical team both during the operation and for post-operative care.
