By making mak-ing a record of these currents, called an "electro - cardiopi am," 1t is possible to know positively whether a heart Is healthy or what form of -Irregularity affects af-fects it. Most people know tLat the heart Is the most essential organ and that it Is the mo.-t overworked muscle of the body The greatest cause of death Is heart disease. Everybody fears heart trouble sooner or later in hla life and becomes worried about Its symptoms. Yet with all the anxiety and thought on the subject thero is very little definite knowledge as to what constitutes con-stitutes reriouv heart trouble. For in-t-tauce. a strong or weak pulee does not, as most people think, prove that you ha 8 D strong or weak heart The lack of general knowledge coneern-lni,' coneern-lni,' heart troubles Is not surprising, as doctors until recently had no certainty in reading the heart's action. All this has br.ji changed by the discovery of the hsarl l electric currents. Dr. Louis Faugorcs Hi&hop, professor of heart and circulatory diseases, ln Kordham University, explains ln a new book the re-i, re-i, :irkable services which are performed by the new electric recording Instruments In diagnosing heart conditions and showing ho., they should bo treated. Dr. Bishop's book Is entitled "Heart Troubles: Their Relief and Prevention" (Funk Be V'ng nails). The three electric currents from t hi r are: a small current caused by the contraction and working of the auricle, vhleh receives the blood: a sharp, quick current caused by the beating of the ven-trlele. ven-trlele. which pumps the blood on. and a ihini slueglsh wave caused by the con-traetlon con-traetlon of the ventricle.

The action of Ihe ventricle is divided into two phase The first phase is a sharp contraction upon the contained blood, and the second phase is a firm, -dow continuation of the primary phase, or sharp contraction, pushing push-ing the blood out of the heart The first current is called the P current, which represents the contraction of the auricles. The second enrrent Is called the R current and represents tho contraction of the ventricles The third current produces pro-duces the T wave, representative of the work of the ventricles The wonderful Instrument called the electro-cardiograph, shows which part of the heart acts first, and which part acts later during all the various combinations that arise ns impulses are generated In oiu' part of the heart or another. If the ventricle acts before the auricle wo see in the record the high, sharp current cur-rent ln the form of a church steeple com ing before the little, high mound that Is characteristic of the current from the auricle. If the Impulse stops at the top of the ventricle and moves to the apex of tho heart, we are the current molng In one direction and the church steeple poinMn upward. If. on the other hand the impulse im-pulse starts at the apex of the ventricle and Journeys toward its base, we have the current travelling ln the opposite direction di-rection and tho church steeple pointing downward These constitute common dl-ordr dl-ordr of tho heart and can only be clear-; clear-; .evealed by the electro-cardiograph. If the heart doos not produce sufficient ' electric force, normally, either It or somo other important organ Is not rleht, and this Ingenious Instrument quickly reveals tho presence of trouble It Is naturally the clearest Indicator of the condition of the heart Itself. If the physician finds that the curves P and T are very low, ho knows at once that the person's heart is weak If R. Instead of rising above the horizontal lines', falls below be-low them, he Is sure that the patient Is suffering from neurosis of tho heart If T falls below the horizontal linos, then it is Testing the Intensity of the Electric Flow from the Heart Uncier the Influence In-fluence of Shock in This case the Discharge Dis-charge of a Pistol. a certain indication of prtorlo-sclerosis, or hardening of the arteries. There are seven varieties of Irregular heart beats that form the basis of functional func-tional heart trouble These aro called (1) Sinus arrhythmi? 2i heart block, (3) premature contractions. (4) simple paroxysmal tachycardia, (6) auricular Mutter, Mut-ter, (6) auricular fibrillation, and (7) alternation al-ternation of the pulso A record by the electro cardiograph will show Immediately which of these lrregu larities affects a patient's heart hat makes the heart beat? This Is another Important matter concerning which science Is making new discoveries Tho question seems so simple that the answer ought to be found by turning over the pages of any book on physiology, but 'intll recently It has been unanswered. There have been two great classes of thore who have tried to solve this question. One :ot of men bellevpd that the origin of the heart beat Is ln the nerves, and later on another, set believed that It was ln the muscle It seenm row that neither of them was ripht. but that tho cause of tho heart beat Is really found ln tho chemistry of the heart, "The hest explanation of modem times," isya Dr Bishop, "Is that there is some substance, the nature of which we do not entirely understand, that Is constantly be-inp: be-inp: formed la certain part of the heart, and when this substance accumulates ln a ceriain amount It generates the beat of the heart. When the heart beats this sub stance Is used up, and another beat docs not happen until enough of It is formed again In that way we have a continuously continu-ously acting cause producing an Intermittent Intermit-tent action " t Now, there Is one spot In the heart where the beat ought to start and spread (O) 1020, IntcrnaticasJ Feature 9rrIco. lat over the whole organ, but sometimes this chemical activity acts In other places and we have the heart heat frenerattnt; sometimes some-times in one part of the heart and sometimes some-times In another .Naturally .Nat-urally this results ln great disorders, and the study of these disorders constitutes an interesting i h tptsr in what we know about the heart. Nearly all the muscles of the body are balanced against each other, so that one group of museles pulls against "the other and keeps everything steady aid In shape. If a muscle become paralyzed Its opposing oppos-ing muscle draws the limb out of shape. So, whtn a child has Infantile paralysis and some of the muscles are paralyzed, great care Is necessary to prevent ever-Im ever-Im re-ulug deformity. The heart is a muscle and its size de ponds upon the tone of tho muscle of Which it Is made up The tone of tho muscle of the heart and of tho muscles which surround all the brood vessels Is r)ocely associated with the tone of the muscles that we use to move our limbs and bodies. For this reason a great resource re-source lu regulating and controlling the condition of the heart and blood vessels ln health and disease Is found In exercise and those things which affect the voluntary volun-tary musclet Blorid pressure Is really pressure on the blood by the contraction of the walls of the hollow places In which it Is contained Juat as If you held something lightly ln your hand and then closed your hand :.

Dr. Bl6hop explains ex-plains that high and low blood pressure are not necessarily dangerous, and that high pressure ln particular Is a condition which often arises to correct some other bodily defect such as weak kidneys and we should be glad we have it. Tho nature of the pulse la another point coneernlng which many wrong Ideas prevail. pre-vail. Per. ons r.f experience learn to tell certain things by feeling the pulse such as whether It Is nearly natural, whether it Is extremely weak or very strong. While many people believe they can tell a good deal bv feeling the pulse, the fact Is that the meaning of the pulse Is difficult to determine, and even thoe who have spent tholr lives ln studying It at times are misled mis-led Tho beat of the pulse is simply a wave that comes from the movement of the heart and has nothing to do with the actual flow of the blood Another fact that shows that the condition con-dition of thS pube must not be takeu too seriously In its apparent poorness of quality qual-ity 1 thet manj persons with Irregular pul.tes pulses that miss beats, take ur V3I wrong beats and have beats of all sizes often show no evidence of poor circulation, while some of the worst cases of failure of circulation that we see aro frequently accompanied ac-companied by a strong and regular pulse. The must reliable figns of henrt trouble are DOt an Irregular pulse, according to Dr Hishop. hut these three thing.-: 1 Shortness of breath. 2. Tenderness over the liver. 1 Swelling of the foeL After years of study of the heart's action, ac-tion, Dr Hishop says he has been greatly Impressed by Its resemblance to the irt ternal combustion engines used in automobiles. auto-mobiles. Ho thinks that if people who own automobiles understand this It will lead them to take care of their hearts. So many people have been compelled to born about gasoline enginos that It ij hardly necessary to explain that the internal in-ternal combustion engine Is made to go by the explosion of gasoline In tho cylln - I dors while a steam engine Is made to go by passing steam Into the cylinders and the steam pushes the piston back ami forth Thr! heart muscle corresponds to the cylinder of tho gasoline engine and gets its energy from the combustion of fond products. When a gasoline engine has had a single explosion In the cylinders nothing moro can happen until sufficient time has elapsed for more gasolne to be taken in. In the meantime, there being no gasolln" present nothing happens. In the same way a stroko of tho heart is followed by a period during which, no matter how much it Is stimulated, it will not work. In oh"r words, with each stroke of the heart all Its available energy Is used up. and more must be produced before It can beat again The boating of the heart, therefore, consists con-sists of a succession of explosions of energy en-ergy just as each throb of the automobile engine represents an explosion of gasoline In its cylinders. To get good results for an engine wo need pure gasoline, a proper mixture of air. regular ignition and a constant load. If you throw out your clutch suddenly when your engine Is speeding up It raecs'-If raecs'-If you overload It It pounds The same thing is true with your heart. To get the ' K best results we must have a proper supply of the right kind of food products, ueitner too much nor too little. We must havo also the kindB that buru up and leave no residue. The Impulse generator of the heart Ilea normally in the auricle and acts much like the commutator of the engine, which should send an average of seventy Impulses Im-pulses a minute, and these impulses should spread quickly over the heart, causing it to contract and do Its work. The blood pressure, llko the load on the engine, must not be too low. because that makes the hart palpitate, nr race, and It must not be too high, became that makes the heart labor or knock MsJ If you want to find out whether a par- fljfff tlculnr food Is good to produce energy in the heart burn It up and see how much heat ymi ran get out of It If It produces little heat and a bad smell It is not good HErl food to make the heart do Its work well jflg Just as heavy crude oil Is not good to use ui an automobile. . , a t - myK y saaaaaaaaaaal |
