Why the study?
Do correlation waveform analysis, amplitude distribution analysis, and spectral analysis accurately distinguish ventricular tachycardia from sinus rhythm using intracavitary ventricular electrograms?
Do correlation waveform analysis, amplitude distribution analysis, and spectral analysis accurately distinguish ventricular tachycardia from sinus rhythm using intracavitary ventricular electrograms?
Correlation waveform analysis provides 100% sensitivity and specificity for distinguishing ventricular tachycardia from sinus rhythm, making it a promising algorithm for implantable antitachycardia devices.
No takes yet. Share an insight, caveat, or question.
May support correlation waveform analysis for device VT detection; hypothesis-generating and requires prospective validation before clinical use.
