Wavelength of reentry – Cardiology MCQ – Answer

Wavelength of reentry – Cardiology MCQ – Answer

Wavelength of reentry is the distance traveled by the reentry wave during a refractory period. Is is – Correct answer:  a) Product of conduction velocity and refractory period

If the wavelength is shorter than that of a potential electrical reentry circuit, it will reach the point of origin during the refractory period and die out. This is because the point of origin remains refractory.

If the wavelength is longer than that of the circuit, it reaches back at the point of origin after it recovers from refractoriness and a reentry is initiated.
