The Electrocardiogram Cards

Description: A large ECG trace on classic millimetre grid paper, labelling the P, Q, R, S, T and U waves, the PR, QRS, ST, QT and TP intervals and segments with normal values, plus a normal sinus rhythm strip in lead II. Part of the Atlas of Medical Science collection: a consistent series of scientific plates with a deep navy background, fine gold frame and precise English labels.

Description: This black background design features bold yellow text in a distressed font. The top line reads "HAVE NO FEAR". Below that, "THE" is in white with yellow horizontal lines on either side. The word "BIOMEDICAL" is prominently displayed, incorporating a caduceus symbol with an asterisk beneath it. The next line reads "ENGINEER" which features a black electrocardiogram waveform integrated into the letters. At the bottom, "IS HERE" is in white text, flanked by two small yellow gears.
