title: Electrocardiographic study of the effect of masturbation normal individuals.
abstract: An electrocardiographic study of 120 normal individuals of age group between 22 years to 38 years was carried out to observe changes manifested in the electrocardiogram under the effect of masturbation. Twelve-lead electrocardiograms was recorded, E.C.G. were taken twice in all the subjects: (i) before ejaculation, and (ii) after ejaculation. After ejaculation, in electrocardiogram, following changes were observed: (i) increase of QRS-amplitude, (ii) increase of T-wave amplitude, (iii) decrease of heart rate, and (iv) elevation of St-segment. Blooe pressure was also estimated in all the subjects before and after ejaculation. Blood pressure levels increased after ejaculation in all the cases. The fact that any sort of stressful condition may induce the discharge of epinephrine and norepinephrine from the adrenal medulla as well as adrenergic nerve endings, led us to estimate the concentration of epinephrine and nor-epinephrine in plasma before and after ejaculation. The result showed, increase of concentration of epinephrine and nor-epinephrine after ejaculation. Hence epinephrine and nor-epinephrine, were thought to be responsible to cause changes in the electrocardiographic pattern after ejaculation.
