The Meaning of Minor T Wave Abnormalities in Insurance Medicine the Meaning of Minor T Wave Abnormalities in Insurance Medicine

Although the impact of an abnormal electrocardiogram upon risk evaluation in insurance applicants continues to be of great importance, some electrocardiographic abnormalities carry more and some less weight. Probably one of the most difficult areas of risk evaluation is the analysis ofT wave abnormalities. The T wave of the electrocardiogram is the most labile, unstable and non-specific compone...

The pace Maker of the Cardiac Ganglion of Limulus .polyphemus

The ganglion on the dorsal surface of the heart of Limulus polyphemus originates the impulses which cause the contractions of the cardiac muscle (1). In large specimens the portion of the dorsal nerve cord which contains the ganglion cells may be 10 or even 12 cm. in length and one naturally wonders where in the extent of this long structure the impulse actually arises. Does it arise in a speci...
