The theme for the World Health Day in 1992 was “Heart beat—the rhythm of health” resulting in the appearance of a few additional stamps featuring the electrocardiogram in their design as well as the heart. The stamps from Zambia and Iran issued for this health campaign are shown. The Iranian stamp is interesting in so far as the electrocardiogram shows ventricular bigeminy whereas, usually, normal electrocardiograms are included in the design. One of the few stamps that contains an electrocardiogram separate from a health or cardiac theme came from Israel in 1968. The 80 agorot stamp is part of a 10 stamp airmail set issued depicting Israeli exports, and features telecommunications equipment and electronics. The other stamps in the set include textiles, fruit, and flowers.
