circa 1550 BCE, Ebers Papyrus, ancient Egypt
For most of recorded history, sudden cardiac death was interpreted through spiritual, humoral, and later mechanical lenses, with physicians attributing the cessation of the heartbeat to divine will, corrupted blood, or failed vital spirits. It was not until the seventeenth and eighteenth centuries that European anatomists and physiologists began to disentangle the heart's mechanical function from metaphysical explanations. The development of resuscitation societies in the 1700s marked the first organized, secular effort to reverse what had previously been accepted as inevitable death.
Historical Narrative
The earliest recorded observations of sudden death linked to the heart appear in ancient Egyptian papyri, where scribes described the heart as the seat of life and consciousness, and its failure as the departure of the soul from the body. Egyptian healers believed the heart communicated with all other organs through channels called metu, and that blockage or corruption of these channels could bring about sudden collapse and death. When the heart stopped, it was generally understood as a withdrawal of divine favor or the completion of a fated span of life, and no attempt was made to reverse it.
Ancient Greek physicians, particularly those working within the Hippocratic tradition, attributed sudden death to an excess of cold, wet humors overwhelming the vital heat of the heart. Aristotle, who believed the heart was the seat of the soul and the origin of all bodily heat, described sudden death as the abrupt extinction of this inner fire. Galen later elaborated on these ideas, asserting that the heart generated pneuma, a vital spirit, and that its sudden failure represented a catastrophic loss of this animating substance. These humoral and pneumatic explanations dominated Western medical thought for over a millennium.
In medieval Islamic medicine, scholars such as Ibn Sina, known in the West as Avicenna, described what he called maut al-faj'a, or sudden death, in his encyclopedic Canon of Medicine. Ibn Sina attributed such events to obstruction of the heart's ventricles and proposed that certain cold foods, emotional shocks, or corrupt air could precipitate the heart's failure. His writings were later translated into Latin and profoundly influenced European physicians through the Renaissance period.
The anatomical revolution of the sixteenth century began to shift understanding away from humoral frameworks. Andreas Vesalius corrected numerous Galenic errors through direct dissection of human cadavers, and William Harvey's landmark 1628 work Exercitatio Anatomica de Motu Cordis et Sanguinis established that the heart functioned as a mechanical pump circulating blood in a closed system. Harvey's discovery did not immediately produce new interventions for sudden cardiac death, but it fundamentally reframed the heart as a physical organ subject to physical laws rather than a mystical vessel of vital spirits.
By the eighteenth century, European physicians and civic reformers began to consider whether sudden death might sometimes be reversible. Drowning and suffocation had long been observed to produce a pulse-less, breathless state from which some individuals spontaneously recovered, and this raised questions about whether death was always instantaneous. In 1767, the Maatschappij tot Redding van Drenkelingen, the Society for the Recovery of Drowned Persons, was founded in Amsterdam, representing the first institutional effort to systematize resuscitation. The society promoted techniques including warming the body, stimulating the airway, and applying bellows to the lungs.
Similar societies appeared in London and elsewhere, and physicians including William Hawes and Thomas Cogan co-founded the Royal Humane Society in 1774 in Britain. These organizations documented cases in which apparently dead individuals were revived and began accumulating the first empirical records of resuscitation attempts. The understanding of cardiac arrest as a potentially reversible physiological event, rather than an absolute endpoint, took its first tentative shape in this era, laying the groundwork for centuries of subsequent investigation.
