In other cases the metaphyses have a "zigzag" or "saw-tooth" appearance, while in milder cases only a portion of the metaphysis is involved. All of the above lesions are considered pathognomonic. When, however, osteogenesis is interfered with to a lesser degree, the x-ray findings are considered as merely suggestive of syphilis..

Saw-tooth cardiomyopathy (STC) is a rare form of left ventricular (LV) dysplasia that may not be represented in the literature because it is underdiagnosed. Cardiac computed tomography is a valuable non-invasive study for the diagnosis of STC due to its capacity to rule out coronary lesions and identify this type of LV dysplasia.

Dr. Smith's ECG Blog What is the rhythm? Answer at the bottom.

if the P waves are about 300 per minute, and there is a 3:1 block, then the ECG will have a characteristic saw-tooth appearance; if atrial flutter is associated with a 2:1 block, P waves are difficult to recognise because of the superposition of the preceding T waves; flutter waves are most clearly seen in V1, II, III & aVF

The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform.It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle.A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform.. The convention is that a sawtooth wave ramps upward and then sharply drops.

In 2009, the first case of saw-tooth cardiomyopathy, a type of "LVNC to the extreme," was reported in a 2-month-old infant. In that case, however, the myocardium appeared compacted, with dramatic cross-bridging muscular projections. Additionally, left ventricular ejection fraction (LVEF) was impaired, and there was an apical aneurysm and a.
