measurements of the sigma r-amplitude as well as of the einthoven/goldberger leads as well as of the wilson leads on the same patient showed higher sigma r-values for the heart beats which were preceded by a short diastolic filling phase ( rapid phase of the absolute arrhythmia , interpolated extrasystoles ) than in the heart beats with previous long diastolic filling time ( slow form of the absolute arrhythmia , extrasystole with compensatory interval ) .
