Somatosensory evoked responses after median nerve stimulation were recorded in 21 patients during hypothermic cardiopulmonary bypass. During hypothermia a significant linear correlation (P less than 0.001) was found between evoked potential latency and temperature. Correlation was best for tympanic membrane temperature during cooling and for perfusate(More)
Background: Irreversibly dysfunctional myocardium is electrically characterized by decreased amplitudes and prolonged duration of local electrograms. We investigated whether ECGs from body surface correlate with epicardial electrograms. Methods: A 120-channel body surface potential mapping (BSPM) was performed in 24 patients before CABG. During CABG(More)
