The recorder has a spare channel, so that if the patient has electrocardiograph leads hooked up the physician can read the ballistocardiogram along with an electrocardiogram...
...physiological measurements, i.e., weight, blood pressure, electrocardiogram, cholesterol count. So far, among other diseases, 27 of the businessmen have suffered heart attacks, 16 of them fatal. The common element in 18 of the cases was high (240-360) cholesterol levels. Moreover, it was the only significant common element.

Brain Researcher Ian Oswald of Oxford University's Institute of Experimental Psychology got interested in it while running sleep experiments. His volunteers were plastered with electrodes for electrocardiograph, breathing and brain-wave records. So he got instantaneous evidence of a burst of high-voltage activity in the brain, and disturbances in the heartbeat and breathing. Dr. Oswald reports in Brain that his first jerk-recording subject was a healthy, athletic type of 22, with no history of head injury or brain damage. But he had several such jerks nearly every night while falling asleep in a normal setting...
