Final answer:
Telemetry is no longer the standard of care for confirming cardiac rhythm before treatment. Paramedics rely on their training and technology to assess the rhythm and make treatment decisions based on protocols.
Step-by-step explanation:
The use of telemetry to confirm cardiac rhythm before treatment is no longer the standard of care because treatment algorithms exist that assist the paramedic in identifying the cardiac rhythm. Telemetry is a method of transmitting data from the patient's heart to a monitor, which can then be used to assess the rhythm and guide treatment decisions. In modern EMS systems, paramedics are trained to use their knowledge and the available technology to assess cardiac rhythm and make independent treatment decisions based on established protocols.
