Bradysphygmia
Historical document, translated for reference. It reflects medical knowledge of the 1920s–30s and is not medical advice.
Summary
Bradysphygmia refers to a slowing of the pulse without a corresponding decrease in heart rate, occurring in cases of pulse deficit. This condition can be caused by ventricular extrasystoles or certain contractions during atrial fibrillation.
Encyclopedia entry (1928–1936)
Bradysphygmia (from Greek bradys- slow and sphygmos- pulse), slowing of the pulse. Under B. is usually understood slowing of the pulse without corresponding slowing of the number of heart contractions, i.e. without bradycardia. B. is observed in the so-called pulse deficit, when some heart contractions, usually inadequate, do not reach the periphery. Such inadequate contractions can be a) ventricular extrasystoles and b) some systoles in atrial fibrillation (arhythmia perpetua). The origin of the pulse deficit, resp. B., can be easily determined by the nature of the rhythm: regular rhythm with drops- in extrasystole, puls. irregular, perpetuus with deficit- in atrial fibrillation.
