Example 1: A patient experiences infrequent palpitations. They are fitted with a mobile cardiac telemetry monitor for 30 days to capture and analyze these episodes., A patient has a history of atrial fibrillation. They undergo continuous ECG monitoring for 30 days to assess the effectiveness of their medication., Following a cardiac event, a patient is placed on a 30-day mobile cardiac telemetry monitor for continuous monitoring and early detection of any recurrent arrhythmias.
