Summary
Diagnosing slow ventricular tachycardia (VT) with implanted pacemaker Holter function is now possible. This method identified previously unrecognized VT episodes, aiding in managing heart failure progression.
Area of Science:
- Cardiology
- Biomedical Engineering
- Electrophysiology
Background:
- Ventricular tachycardia (VT) diagnosis can be challenging, especially slow, hemodynamically stable forms.
- Implanted pacemaker Holter functions are primarily used for pacing optimization, not routine arrhythmia diagnosis.
Observation:
- A patient with progressive heart failure experienced unrecognized, long-lasting episodes of slow VT.
- The patient's symptoms did not correlate with perceived VT recurrences.
Findings:
- Prospective 24-hour ECG analysis and pacemaker Holter data comparison established novel diagnostic criteria for VT detection.
- These criteria enabled retrospective diagnosis of VT episodes occurring when the patient was outside the hospital.
Implications:
- Pacemaker Holter function can be utilized for diagnosing VT, improving patient management.
- This approach may prevent delayed diagnosis and subsequent heart failure progression in similar cases.
