Peripheral Heart Action

The active principle of tobacco is nicotine, besides which it contains a substance camphor affectiant aromatic, a cellulose, a resins, a sugar, etc. The other developed products during the combustion are gas monoxyde of carbon, a meticulous quantity of acid of prussic and in some varieties a lot of furfural, a poison. Of any a cigar or of any cigarette but the small nicotine is absorbed, of other the user would be poisoned.

The action more important of nicotine is on the circulation. The heart is done frequently quicker and arterial tension certainly is raised in an ordinary smoker, while even a novice can obtain first an increase, but soon it can become depressing and has a decrease of the pressure. While a moderate smoker can have an increase of 10 mm. in arterial tension, an excessive smoker can show but the small change. Maybe this is because his heart muscle became weakened. If arterial tension of the person is high, the heart cannot increase in the rapidity during to smoke, and if it is nervous and is in advance calmed by his tobacco, the pulse will be slowed down. It was showed that the rate of arterial tension and pulse could be affected in the persons that asseyent in a full piece of smoked one, although they do not smoke themselves. The stopwatch length the increased pressure continues depends on the person, and it is this diminishing pressure that causes a lot to take a smoked other. The heart is slowed down by the action of nicotine on the wailed, as these nerves the two are stimulated in a manner centralized and peripheral. An overdose of nicotine will paralyze the wailed. The heart action becomes then the quick and maybe irregular one. The heart muscle first is stimulated, and so too big a dose is taken, or too in twenty-four hours, the muscle becomes depressing and maybe debility. The consequence of such action on the heart muscle, or late, is earlier an expansion of the left ventricule if the abuse of tobacco is continued.

In a word, the heart muscle always is weakened by the excessive indulgence in the nicotine, the nerves of the heart are disturbed, if not in injured fact. Therefore everyone that the smokes should stop it.
