The non-specific nature of the myocardial wavy fibre.
Wavy myocardial fibres were found in about half each of a series of 28 normal and 31 infarcted human hearts, as well as in the normal heart of an infant. Such fibres were also seen in rather more than half of a series of normal rat hearts. Thus, the wavy fibre is not a specific feature of acute ischaemic heart disease. Some experimental evidence was obtained that patchy loss or preservation of ATP promotes the formation of wavy fibres.
