Overview
ECG editing may aid MDCT coronary angiography in mild arrhythmias; hypothesis-generating pending prospective validation.
Structured PICO
Does ECG editing improve the diagnostic accuracy of MDCT coronary angiography in patients with mild heart rhythm irregularities?
P
Population
38 patients with mild heart rhythm irregularities (premature beats, atrial fibrillation, mistriggering, or low heart rate ≤40 bpm) who underwent MDCT coronary angiography and conventional coronary angiography
I
Intervention
MDCT coronary angiography with ECG editing (arbitrary modification of temporal windows within the cardiac cycle at the site of mild heart rhythm irregularities)
C
Comparator
MDCT coronary angiography before ECG editing
O
Outcome
Diagnostic accuracy (sensitivity, specificity, negative and positive predictive values) for the detection of significant stenoses (≥50% lumen reduction) in coronary segments ≥2 mm diametersurrogate
ECG editing significantly improves the diagnostic accuracy and interpretability of MDCT coronary angiography in patients with mild heart rhythm irregularities.
