Abstract

A new non-contact technique for transduction of the kinetocardiogram has been investigated. The technique offers the prime advantage of complete isolation from the chest wall. Possible distortion due to source loading is eliminated. Other very desirable features are ease of utilization and the ability to produce consistent qualitative results. The technique is based on air-coupled ultrasonic transducers, operating slightly above audible frequencies.
