The document discusses heart sounds and murmurs. It describes the four normal heart sounds: S1 caused by AV valve closure, S2 caused by semilunar valve closure, S3 associated with blood flowing into ventricles, and S4 associated with atrial contraction. It notes S1 and S2 are normally audible. It provides details on S1 occurring with ventricular contraction and AV valve closure, and S2 occurring with ventricular dilation and semilunar valve closure. Heart murmurs result from turbulent blood flow and can be systolic or diastolic, caused by valve stenosis, insufficiency, increased blood flow, or decreased viscosity. The two basic types of valvular disease are stenosis which is

Heart Sounds.pptx
The document discusses heart sounds and how they are generated. It explains that heart sounds are produced by the flow of blood through the heart's chambers and valves as they open and close. There are normally two main heart sounds, S1 and S2, produced by the closing of the atrioventricular valves and semilunar valves respectively. Additional sounds S3 and S4 may sometimes be heard and indicate cardiac abnormalities. Auscultation of the heart with a stethoscope allows doctors to detect normal and abnormal heart sounds and murmurs which provide information about heart function and identify potential issues requiring further evaluation.
Heart Sounds.Cardiovascular system by Dr Farhan KGMC peshawar
Heart sounds are produced by the closing of heart valves. The first heart sound (lub) is caused by closure of the atrioventricular valves starting systole, and the second sound (dub) is caused by closure of the semilunar valves ending systole. Four heart sounds are clinically important - S1 and S2 are normal systolic sounds, while S3 and S4 may indicate pathology when heard in adults. Heart sounds are auscultated and can be recorded as phonocardiograms to analyze the timing and intensity of the sounds.
Heart sounds
The document discusses heart sounds and murmurs. It describes the four normal heart sounds heard during the cardiac cycle known as S1, S2, S3, and S4. S1 and S2 are the loudest and resemble "lub" and "dub". S3 is softer and S4 is only audible in pathological conditions. Abnormal heart sounds called murmurs can be caused by various valve issues or septal defects. Murmurs are classified as systolic, diastolic, or continuous based on when they occur in the cardiac cycle.

This document discusses how to use a stethoscope to listen to heart sounds and identify different types of sounds. It describes the two sides of the stethoscope - the bell for low tones and the diaphragm for high tones. There are normally two main heart sounds, S1 and S2, which correspond to valve openings and closings in the cardiac cycle. Additional sounds like S3 and S4 can indicate medical conditions - S3 often suggests heart failure while S4 may suggest hypertension. The document provides details on the timing, causes and locations for optimal auscultation of each type of heart sound.
Heart sounds
The document discusses heart sounds and murmurs. It describes the normal S1 and S2 heart sounds which correspond to valve closures. The S3 and S4 sounds indicate pathology, with S3 associated with left ventricular failure and S4 with stiff ventricles. Murmurs are abnormal sounds caused by turbulent blood flow through stenotic or leaky valves. Systolic murmurs occur between S1 and S2 while diastolic murmurs occur between S2 and S1. The timing, location and quality of murmurs provide clues to the type of underlying valve abnormality.

Heart sounds are produced when the heart valves snap shut during each cardiac cycle. The two main sounds are S1 and S2, which occur when the atrioventricular and semilunar valves close at the beginning and end of ventricular systole, respectively. Abnormal heart sounds called murmurs occur due to turbulent blood flow caused by issues like valvular abnormalities or narrowing of blood vessels. The four main types of murmurs are aortic stenosis, aortic regurgitation, mitral regurgitation, and mitral stenosis, each with distinct characteristics in terms of timing and sound.

Cvs examination
This document provides details on performing a cardiovascular examination, including inspection, palpation, percussion, and auscultation. It describes how to evaluate heart sounds and murmurs through auscultation of specific areas of the heart. Key areas covered include the four heart sounds (S1, S2, S3, S4), splitting of S1 and S2, abnormalities in intensity and timing of heart sounds, systolic and diastolic murmurs based on timing and cause, and grading murmurs based on intensity among other characteristics. The goal is to identify any abnormalities that could indicate cardiovascular diseases or conditions.
Conducting system of the heart
The conducting system of the heart includes the sinoatrial node, atrioventricular node, bundle of His, and Purkinje fibers, which transmit the impulse for cardiac contraction. There are four heart sounds but only the first (S1) and second (S2) can be heard with a stethoscope. S1 is caused by closure of the mitral and tricuspid valves at the start of systole, while S2 is caused by closure of the aortic and pulmonic valves at the end of systole. The normal adult resting heart rate ranges from 60 to 100 beats per minute, and the pulse is felt at arteries like the radial artery where pressure differences are transmitted through the arterial walls with each

How to Predict Vendor Bill Product in Odoo 17
This slide will guide us through the process of predicting vendor bill products based on previous purchases from the vendor in Odoo 17.
How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

- 1. Heart Sounds & Murmurs Dr. Arun Goel Associate professor Department of Physiology
- 2. Heart Sounds
- 3. Heart sounds ๏ S1 โ โlubbโ caused by the closing of the AV valves ๏ S2 โ โduppโ caused by the closing of semilunar valves ๏ S3 โassociated with blood flowing into the ventricles ๏ S4 โassociated with atrial contraction Four heart sounds can be recorded by phonocardiography, but normally only the first and the second heart sounds, are audible through a stethoscope
- 4. First heart sound โข occurs when the atrioventricular (AV) valves close at the beginning of ventricular contraction โข generated by the vibration of the blood and the ventricular wall โข is louder, longer, more in duration than the second heart sound
- 5. Second heart sound โข occurs when aortic and pulmonary semilunar valves close at the beginning of ventricular dilation โข generated by the vibration of the blood and the aorta โข Aortic valve closes slightly before pulmonary valve โข Splitting of S2
- 6. Heart Murmur โข Cardiac murmurs are abnormal heart sounds in the form of noises resulting from turbulent blood flow, โข Murmurs may be: โ Systolic murmurs, if they occur during systole. โ Diastolic murmurs, if they occur during diastole โข Causes: โ Stenosis (narrowing) of heart valves โ Incompetence of heart valves โ Increase of blood flow or decrease of blood viscosity (as in anemia).
- 7. Two Basic Types of Valvular Diseases valvular stenosis: โข narrowing of the valve valvular insufficiency (incompetence): โข valve is unable to close fully; so there is regurgitation
- 9. Thank You
