An ECG records the heart's electrical activity. A wearable monitor extends that recording into everyday life or allows monitoring around a hospital ward. The most useful question is how your particular recording will be reviewed and acted on.
“Wireless” describes a connection. It does not establish that someone is watching continuously, that the device detects every problem, or that it can treat a rhythm disturbance. Ask for the device name and the service's written instructions.
Recording and reviewing are separate steps
On a small screen, scroll the table sideways to read all columns.
| Arrangement | How information is used | Clarify with the team |
|---|---|---|
| Hospital telemetry | A wearable unit sends signals to a hospital monitoring system. | Where you may walk and how to alert staff to symptoms. |
| Holter or ambulatory recorder | Records over an agreed period, often for analysis after return. | Recording duration, return method and when results will be reviewed. |
| Patch monitor | An adhesive form of ambulatory monitor; capabilities vary by model. | Whether it stores or transmits data and how symptoms are marked. |
| Event recording | Records episodes through patient activation, automatic detection, or both, depending on the device. | What you must do when symptoms occur and who receives the recording. |
NHLBI explains ECG and longer-term recording in arrhythmia diagnosis. An office ECG captures a shorter window; longer recording can help investigate intermittent symptoms. A recording still needs clinical interpretation.
Chelsea and Westminster describes hospital monitoring and the signal sent to the nurses' station. Report symptoms directly to staff even while wearing a monitor. Ask the nurse before leaving the monitored area or disconnecting equipment.

Before leaving the fitting appointment, ask about bathing, exercise, sleep, skin irritation, loose electrodes, charging and any scheduled imaging. Water rules differ between products. Confirm who handles a detached patch or an error message and retain the packaging needed for return.
For example, North Bristol's ambulatory service describes fitting, a symptom button and later analysis. Those details belong to its service and equipment. Use them as prompts for questions, not replacement instructions for a different recorder.
Make a symptom entry useful
Record the date, time using the clock specified by your service, what you felt, approximately how long it lasted, and what you were doing. Add whether you used the event button if instructed. Gateshead's monitor guidance explains the link between diary times and recordings. Return the diary as directed even if no symptoms occurred.
Illustrative log entry
“Tuesday, 14:10 on recorder; fluttering feeling while sitting; about two minutes; event button pressed as instructed.” This invented example supplies timing and context without guessing the rhythm diagnosis. Describe your actual experience in your own words.
Use the printable symptom log or its editable text version. Recording symptoms should never delay seeking help. For severe chest pain, severe breathlessness, collapse or a suspected emergency, call the local emergency number instead of waiting for the recording to be reviewed.
Close the loop after recording
Record the stop time, return deadline, requesting clinician and expected route for results. If symptoms did not happen during the test, tell the clinician; this is useful context for deciding whether more assessment is needed. Ask what the findings establish and how they affect the next step.
A monitor records information; an implanted defibrillator has treatment functions. See the ICD guide for that distinction, and the home monitoring guide for questions about remote review and response arrangements.
