Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult presenting to an outpatient clinic with symptoms such as palpitations, dizziness, or suspected arrhythmias. The physician determines that extended cardiac monitoring is necessary to capture intermittent events that may not be detected during a standard ECG or Holter monitor. The patient is provided with an external mobile cardiovascular telemetry device, which records ECG data continuously for up to 30 days. The device transmits both patient-activated and automatically detected events to a remote surveillance center, where data is reviewed in real time. After the monitoring period, a physician or qualified healthcare professional reviews and interprets the collected data and generates a report for clinical decision-making.
