Final answer:
The correct answer is d) Telemetry over UHF frequencies enables transmission and analysis of all 12 leads, as ECG telemetry is crucial for accurate heart monitoring using a 12-lead ECG, and technological advancements have improved diagnosis and intervention for cardiac events.
Step-by-step explanation:
The correct statement regarding 12-lead ECG telemetry is d) Telemetry over UHF frequencies enables transmission and analysis of all 12 leads. A 12-lead ECG provides a wealth of information about the heart, including the detection of regions of damaged heart tissue called infarcts. For accurate diagnoses, changes in the heart are detected by comparing a recent ECG to an older one. ECG technology has advanced, integrating portable ECG monitors into wearable devices and emergency vehicles, enhancing the ability to monitor heart activity continuously.
Most newer systems of ECG telemetry have progressed beyond facsimile technology and now use more sophisticated means for transmission including wireless technologies. Decoders are also not typically mentioned as being required to filter out voice communication in the context of ECG transmission. Lastly, the assertion that telemetry has never proven to increase diagnosis times is incorrect, as advancements in ECG telemetry have improved rapid diagnosis and intervention for cardiac events.
