Centuries later, the English physician William Harvey (1578-1657) was still not able to explain this in his De motu cordis (1628). 129-c.216 CE, state physician to Marcus Aurelius) wrote that the excised hearts of animals continued to beat for some time, but he did not provide an explanation. Physicians and philosophers debated for centuries on the origin of the heartbeat. Origin of heartbeat: myogenic versus neurogenic theory It became increasingly possible to do research not only in animals, but also in humans. In the 19th century, anatomy and physiology expanded when more instruments were invented and made available. Some decades later, Giovanni Morgagni (1682-1771, a pupil of Antonio Valsalva) described the course of a patient with AV block in De sedibus et causis morborum per anatomen indagatis. This observation was published after his death. In 1717, Marcus Gerbezius (1658-1718) performed a very accurate pulse analysis and described symptoms of bradycardia, probably induced by a complete AV block. Many centuries later in Europe, Sanctorius Sanctorius (1561-1636) developed techniques for clinical measurements such as pulse rate. The ancient Egyptians described the pulse in the ‘Eber-papers’. ![]() It all started much earlier: in the Chinese and Arab world, pulse measurement had already been practiced for centuries: Wang Chu Ho was said to have authored ten books alone on the pulse by 280 BC and Pien Ts’lo is said to have been the first to have recognised the pulse as a diagnostic toom in the fifth century. Centuries of discourse on anatomy and physiology passed before recording ECGs became feasible. Although electrophysiology may sound like a new field, bioelectricity (in animals) was discovered in 1791 by Luigi Galvani (1737-1798). ![]() Today we take our smartphone and use two fingers to register an ECG. The patient had to put two hands and one foot in a bucket with electrolyte solution to obtain a 3-lead electrocardiogram (ECG). Willem Einthoven (1860-1927) needed a 600-pound machine and five operators to capture the first PQRST complex in a human in 1901.
