Reduced turbulence slope variability precedes VT/VF; hypothesis-generating for imminent arrhythmia prediction and requires prospective validation.
Do heart rate turbulence parameters change preceding imminent ventricular tachyarrhythmias?
Heart rate turbulence slope is reduced immediately preceding ventricular tachyarrhythmias, particularly in patients with normal baseline turbulence, suggesting a potential marker for imminent arrhythmias.
