Writing Device Clinic Letters After Pacemaker and ICD Reviews

The problem

Device clinic letters are repetitive to write. The structure is broadly the same for every review: device interrogation findings, battery status, sensing and pacing parameters, any treated episodes, medication review, and plan. The variation is in the clinical details, but the framework is almost identical from patient to patient.

Writing fifty structurally similar letters a week is not a good use of clinical time. It is also the kind of repetitive task where fatigue-related errors are more likely to creep in.

How AI helps

An AI tool can take a brief clinical summary of a device review and produce a formatted letter that covers all the standard sections. You provide the key findings. The tool produces the structure and the prose. You check every clinical detail, add anything missing, and finalise.

This approach works well for routine device review letters — pacemaker battery checks, remote monitoring summaries, and routine ICD follow-ups where no significant clinical event has occurred. For letters following a shock, a lead failure, or a significant change in device behaviour, the clinical complexity warrants a more carefully written letter with less reliance on drafting tools.

A real example

Dr Amelia is a consultant cardiologist who runs a device clinic. After a morning of twelve device checks, she has a stack of correspondence to complete. Most are routine. One is a patient in her late sixties with a dual-chamber pacemaker, pacemaker-dependent, presenting for a scheduled annual review. Battery is at an elective replacement indicator.

She opens an AI tool and types:

Draft a device clinic letter for a pacemaker annual review. 
Use professional medical language with the following headings: 
Device Details, Interrogation Findings, Clinical Assessment, Plan.

Clinical details:
- Patient: woman, late sixties, complete heart block, pacemaker-dependent
- Device: dual-chamber pacemaker, implanted approximately 8 years ago
- Battery: at elective replacement indicator
- Lead parameters: satisfactory sensing and pacing thresholds, impedances 
  within normal range
- No arrhythmia episodes detected
- Patient: asymptomatic, no palpitations, no pre-syncope
- Plan: refer for device replacement in next 3 months; remote monitoring 
  to continue; GP letter to follow; patient advised of battery status 
  and need for replacement procedure

Do not include specific device model, serial number, or patient identifiers.

The tool produces a four-section letter in twenty seconds. Dr Amelia reads it, adds the specific impedance values and sensing thresholds from her device print-out, corrects the battery indicator description to match her unit's standard terminology, and removes one sentence that incorrectly implied the replacement was urgent rather than elective. The letter is ready in four minutes.

Try it yourself

Things to watch for

Lead parameter values must be added by you. The tool cannot generate accurate impedance, sensing threshold, or pacing threshold values — it will either omit them or insert plausible-sounding numbers that are not the patient's actual values. You add these from the device print-out after reviewing the draft.

Battery status terminology varies. Different manufacturers use different terminology for battery depletion stages. The tool will use standard terms. Check that the term used matches the manufacturer's language and your unit's documentation standard.

Shocked episodes require more careful letters. If a patient has received a shock since the last review — whether appropriate or inappropriate — the letter requires a more detailed clinical account than a drafting tool can reliably produce. Use the tool only for the structural framework in those cases, and write the clinical account yourself.

Remote monitoring letters require specific phrasing. If your service uses remote monitoring and the letter needs to address what was reviewed remotely versus in person, check the tool's phrasing against your service's standard documentation.

Remember: AI is a helpful assistant, not a clinician. You make the call.
