LIVE ECG streaming
ECG data is transmitted during the monitoring period, supporting review of qualifying events while the study is active.
Post-TAVR Cardiac Monitoring
Ambulatory cardiac monitoring after TAVR helps structural heart teams extend rhythm surveillance beyond discharge, including delayed conduction disturbances and clinically important arrhythmias when ordered by the treating physician. Specialized Medical supports selected post-TAVR pathways with Mobile Cardiac Telemetry (MCT), LIVE ECG transmission when connectivity is available, physician-prescribed notifications, and physician-ready reporting.

Why Cardiac Monitoring After TAVR Matters
TAVR can affect the heart’s electrical conduction system. Although many conduction disturbances are recognized before discharge, clinically important abnormalities may also appear later. Published studies have identified delayed high-grade atrioventricular block and complete heart block during ambulatory monitoring after TAVR, sometimes leading to permanent pacemaker implantation. For selected patients, outpatient ECG monitoring can extend rhythm surveillance beyond the hospital stay and provide the treating team with clinically relevant information during recovery.
Specialized Medical’s LIVE Mobile Cardiac Telemetry workflow helps physicians identify concerning rhythms while the study is still underway.
Detecting Delayed Heart Block After TAVR
One of the most important reasons to consider ambulatory monitoring after TAVR is the possibility of delayed atrioventricular conduction disease. Monitoring may identify Mobitz II second-degree AV block, high-grade AV block, complete heart block, significant bradycardia and pauses that were not apparent at the time of discharge. Specialized Medical’s LIVE STREAMING platform can present qualifying ECG findings according to the physician’s prescribed notification protocol, allowing the clinical team to review the information while monitoring is still underway. The treating physician remains responsible for diagnosis and treatment decisions.
Which Patients May Benefit From Outpatient Monitoring?
Patient selection and monitoring duration should be determined by the treating heart team. ACC expert consensus identifies post-procedure conduction changes that may warrant continued telemetry and outpatient monitoring, including new or progressive AV block, new bundle branch block, and progression of baseline conduction disease.[1] Baseline right bundle branch block, PR prolongation, QRS changes, new left bundle branch block and transient heart block are clinically relevant considerations.
- New left bundle branch block after TAVR
- Baseline right bundle branch block or other pre-existing conduction disease
- New or progressive first- or second-degree AV block
- PR or QRS prolongation after the procedure
- Transient intraprocedural or post-procedural heart block
- Unexplained dizziness, presyncope, syncope, palpitations or bradycardia
- Patients selected by the structural heart or electrophysiology team for extended surveillance
LIVE Monitoring Designed for Structural Heart Teams
Specialized Medical combines LIVE ECG monitoring streaming with continuous operational monitoring of device status, battery level, electrode connection, signal quality, cellular connectivity and patient connection status. Qualifying rhythm findings can be presented according to the physician’s prescribed notification protocol, while final reports are prepared for physician review. Multi-carrier connectivity using available nationwide networks helps the system remain connected as patients recover at home and resume normal daily activities.

Multi-carrier connectivity
The monitoring system uses available cellular pathways to support connectivity across urban and rural areas.
Physician-ready reports
Reports organize clinically relevant ECG findings for physician review and interpretation.
Patient and office support
Specialized Medical helps manage enrollment, monitoring workflow, technical support and reporting.
The wearable platform is the S-Patch cardiac monitoring system, configured for the prescribed post-TAVR ambulatory study.
Clinically Important Rhythms After TAVR
Post-TAVR monitoring is not limited to atrial fibrillation. Depending on the patient and prescribed monitoring protocol, clinically important findings may include:
- High-grade atrioventricular block
- Complete heart block
- Mobitz II second-degree AV block
- Progressive bradycardia and significant pauses
- New atrial fibrillation or atrial flutter
- Supraventricular tachycardia
- Ventricular tachycardia or wide-complex tachycardia
- Changes in conduction intervals or rhythm patterns that warrant physician review
Compliance wording
Specialized Medical detects, records, identifies ECG findings and presents qualifying findings. The system does not diagnose, treat, prevent or guarantee avoidance of hospitalization, stroke, sudden death or pacemaker implantation.
A Practical Post-TAVR Monitoring Workflow
- Risk assessmentReview baseline ECG, conduction history and procedural factors.
- TAVR and inpatient observationMonitor for new AV block, bundle branch block, PR/QRS changes and transient heart block.
- Physician-directed discharge planSelect appropriate patients and monitoring duration based on clinical findings and institutional protocol.
- LIVE outpatient monitoringBegin monitoring promptly after discharge; maintain operational visibility and apply prescribed notification thresholds.
- Clinical review and final reportingReview qualifying findings during the study and the final report at completion; determine any treatment or follow-up.
Clinical Evidence for Post-TAVR Monitoring
The following summaries reflect published guideline and peer-reviewed evidence. Citations link to primary ACC or PubMed records. Specialized Medical did not claim proprietary authorship of these study results.
ACC Expert Consensus Decision Pathway (2020) [1]
Patients with new or progressive conduction disturbances may require continued inpatient telemetry and outpatient monitoring for at least 14 days. The pathway identifies new AV block, new bundle branch block and progression of baseline conduction disease as important post-TAVR considerations.
ACC Key Points / JACC consensus
Tian et al., 2019 — 30-day monitoring [2]
In a prospective TAVR cohort, 30-day continuous ambulatory monitoring identified late symptomatic bradycardia and advanced AV block. Among monitored patients without a pacemaker at discharge, 8.6% required a pacemaker within 30 days; the authors concluded monitoring identified additional patients requiring permanent pacing.
Circ Cardiovasc Interv. PMID 31833417
Muntané-Carol et al., 2021 — 14-day monitoring [3]
In 459 patients monitored for 14 days after TAVR, delayed high-grade AV block or complete heart block occurred in 4.6%, at a median of five days after the procedure; 81% of those patients received a permanent pacemaker.
JACC Cardiovasc Interv. PMID 34949396
REdireCT TAVI, 2022 [4]
Two-week remote monitoring before and after TAVI was feasible and generated notifications for AV block, pauses and ventricular tachycardia; monitoring frequently led to planned pacemaker implantation.
Europace. PMID 35699482
Systematic AECG monitoring study, 2026 [5]
A large observational analysis found systematic 14-day ambulatory ECG monitoring after TAVR was associated with earlier detection of severe arrhythmias and fewer life-threatening cardiovascular events at one year. Because the study was observational, this is reported as an association, not proof of causation.
PubMed PMID 42059075
Follow-Up Alone vs LIVE Ambulatory Monitoring
| Consideration | Follow-up without continuous ambulatory monitoring | LIVE ambulatory monitoring |
|---|---|---|
| Rhythm visibility | Intermittent office visits and symptom-driven follow-up | Continuous ambulatory ECG collection during the prescribed period |
| Delayed heart block | May not be apparent during a scheduled office encounter | Qualifying AV block, bradycardia or pauses may be identified during monitoring |
| Patient symptoms | Relies heavily on patient recognition and communication | Patient-triggered symptoms can be correlated with ECG; auto-detected findings may also be reviewed |
| Operational status | No continuous device oversight | Battery, electrode status, signal quality and connectivity can be monitored |
| Clinical response | Information may be available only after a visit or final report | Qualifying findings may be presented while the study remains active, based on prescribed protocol |
