Relation of the ballistocardiogram to left ventricular pressure measurements in man

The Cardiovascular Responses to the Addition of Nitrous Oxide to Fluroxene in Man

“…The beta effects are evidenced by the increased heart rate, mean rate of left ventricular ejection and the ballistocardiographic IJ-wave. The latter is a particularly sensitive indicator of myocardial function (Starr, Schnabel and Mayoch, 1953;Noordergraaf, Verdouw and Boom, 1963;Winter et al, 1967;Harrison et al, 1969;Smith, Van Citters and Verdouw, 1970). Some indirect evidence suggests that part of the phenomenon seen with fluroxene may be due to sympathetic activation.…”
