Q: Question: Does biventricular pacing affect microvolt T-wave alternans in heart failure patients?
Answer: There is a high level of concordance between MTWA test results obtained during RA pacing and other pacing modalities, and MTWA assessment seems not to be influenced by BiV stimulation in congestive heart failure patients. In general, BiV pacing does not seem to affect an arrhythmogenic substrate as detected by MTWA testing.
A:
no
