Reduced heart rate response after premature ventricular contraction depending on severity of atrial fibrillation symptoms – Analysis on heart rate turbulence in atrial fibrillation patients

Conclusions The usual heart rate acceleration after premature ventricular contraction is significantly diminished in pts with milder AF symptoms as compared to pts with severe AF symptoms. The mechanism of association between this diminished response and symptoms should be further investigated.
