Ashcheulova, O.M. Kovalyova, O.V. Honchar. – Kharkiv: KhNMU, 2017. – 20 с. Authors: Т.V. Ashcheulova O.M. Kovalyova O.V. Honchar AUSCULTATION OF THE HEART To understand the underlying mechanisms contributing to the cardiac tones formation, it is necessary to remember the sequence of myocardial and valvular action during the cardiac cycle. During ventricular systole: 1. Asynchronous contraction, when separate areas of myocardial wall start to contract and intraventricular pressure rises. 2. Isometric contraction, when the main part of the ventricular myocardium contracts, atrioventricular valves close, and intraventricular pressure significantly increases. 3. The ejection phase, when the intraventricular pressure reaches the pressure in the main vessels, and the semilunar valves open. During diastole (ventricular relaxation): 1. Closure of semilunar valves. 2. Isometric relaxation – initial relaxation of ventricular myocardium, with atrioventricular and semilunar valves closed, until the pressure in the ventricles becomes lower than in the atria. 3. Phases of fast and slow ventricular filling - atrioventricular valves open and blood flows from the atria to the ventricles. 4. Atrial systole, after which cardiac cycle repeats again. The noise produced By a working heart is called heart sounds. In auscultation two sounds can be well heard in healthy subjects: the first sound (S1), which is produced during systole, and the second sound (S2), which occurs during diastole.

    CHAPTER 1 The Cardiovascular Examination KEY POINTS • The cardiovascular examination lends itself to a systematic approach. • The examination should be thorough but should be directed by the history to areas likely to be relevant. • Certain cardiovascular signs are quite sensitive and specific. • When the examination is well performed, many unnecessary investigations can be avoided.

  • Triple Heart Rhythm*
    TRIPLE HEART RHYTHM * BY WILLIAM EVANS From the Cardiac Department of The London Hospital Received August 28, 1943 Triple heart rhythm stands for the cadence produced when three sounds recur in successive cardiac cycles, just as two sounds compose the familiar dual rhythm of cardiac auscultation, and more rarely, four sounds a quadruple rhythm. The conflicting views on the subject have long served to discourage attempts at a clinical perception of the problem. Disagreement is perhaps best illustrated by recounting the varied terminology employed to describe it. Thus we have gallop rhythm, canter rhythm, and trot rhythm; presystolic gallop, systolic gallop, protodiastolic gallop, and mesodiastolic gallop; complete summation gallop and incomplete summation gallop; auricular gallop, ventricular gallop, and auriculo-ventricular gallop; true gallop; left-sided gallop and right-sided gallop; rapid-filling gallop; diastolic echo; mitral opening snap; reduplication of first sound and reduplication of second sound; Potain's murmur; third heart sound and fourth heart sound. Others may have escaped my notice. This muddled nomenclature, as long as it stands, will frustrate any attempt to unify the many views held on triple rhythm. There is need of a simplified terminology based on clinical findings. It is indeed clear that a neglect of the clinical aspect on the one hand, and a persistence on the part ofmany to explain the mechanism of the supernumerary sound on the other hand, and to classify triple rhythm in accordance with sound records, have been largely responsible for obscuring this common form of cardiac rhythm. Phonocardiography need not become a routine test in clinical cardiology; when it has helped to establish a classification of triple rhythm it will have achieved its main purpose, though it will still serve in other auscultatory problems.

  • The Effect of Posture on Added Heart Sounds
    Br Heart J: first published as 10.1136/hrt.25.1.69 on 1 January 1963. Downloaded from THE EFFECT OF POSTURE ON ADDED HEART SOUNDS BY PHILIP RODIN* AND BERNARD TABATZNIK From the Department ofMedicine, The Johns Hopkins Hospital, Baltinmore, Maryland, U.S.A. Received June 18, 1962 The value of change of posture in discriminating between the various added heart sounds has not been generally recognized. Moreover, apart from Evans' study in 1943, the influence of heart failure on the results has received little attention. Thayer (1909) stated that the physiological third heart sound was rarely heard in the erect posture, and Boyer, Eckstein, and Wiggers (1940) could record the sound more commonly in recumbent than in sitting subjects. Evans (1943) also found that the physiological third sound usually disappeared when the upright posture was adopted whereas the third sound associated with heart failure usually remained audible. The atrial sound disappeared in 31 of 33 patients, mostly with coronary arterial disease or hypertension, when the erect posture was assumed (Engelbertz, 1953), and in 9 of 18 patients when sitting upright with the feet down (Parry and Mounsey, 1961). Mitral opening snaps persisted in the erect posture but the interval between the second sound and the snap was usually increased (Sch6lmerich and Gehl, 1951; and Surawicz, 1957). In the present study we have investigated the effect of posture on the atrial sound, physiological and pathological third heart sounds, quadruple rhythm, pulmonary and aortic early systolic ejection sounds, and mitral opening snaps. In addition, some observations on the effect ofchange ofposture http://heart.bmj.com/ on the widely-split second sound are reported in order to help assess the value of the manoeuvre in differentiating this splitting from the mitral opening snap.

Abstract: The automated classification of heart sounds plays a significant role in the diagnosis of cardiovascular diseases (CVDs). With the recent introduction of medical big data and artificial intelligence technology, there has been an increased focus on the development of deep learning approaches for heart sound classification. However, despite significant achievements in this field, there are still limitations due to insufficient data, inefficient training, and the unavailability of effective models. With the aim of improving the accuracy of heart sounds classification, an in-depth systematic review and an analysis of existing deep learning methods were performed in the present study, with an emphasis on the convolutional neural network (CNN) and recurrent neural network (RNN) methods developed over the last five years. This paper also discusses the challenges and expected future trends in the application of deep learning to heart sounds classification with the objective of providing an essential reference for further study.

All rights reserved. 2 Eko AI Validation White Paper AI Indications for use: The Eko AI software is intended to provide support to the physician in the evaluation of patients’ heart sounds and ECGs. The software analyzes simultaneous ECG and heart sounds and will detect the presence of suspected murmurs in the heart sounds. The software also detects the presence of atrial fibrillation and normal sinus rhythm from the ECG signal. In addition, it calculates certain cardiac time intervals such as heart rate, QRS duration, and electromechanical activation time (EMAT). The software does not distinguish between different kinds of murmurs and does not identify other arrhythmias. Eko AI is not intended as a sole means of diagnosis. The interpretations of heart sounds and ECG offered by the software are only significant when used in conjunction with physician over-read and when used on adults (> 18 years). Introduction As one of the oldest clinical evaluation methods, auscultation has faced scrutiny for its subjectivity, inability to quantify cardiovascular and pulmonary problems, and imprecision. A study (Vukanovic-Criley et al., 2006) of medical school students, residents, cardiology fellows, and physicians integrated visual and auditory (auscultation) data into a measure of cardiac examination competency.
