The apex beat (lat. ictus cordis), also called the apical impulse, [1] is the pulse felt at the point of maximum impulse (PMI), which is the point on the precordium farthest outwards (laterally) and downwards (inferiorly) from the sternum at which the cardiac impulse can be felt.
Heart sounds result from reverberation within the blood associated with the sudden block of flow reversal by the valves closing. Because of this, auscultation to determine function of a valve is usually not performed at the position of the valve, but at the position to where the sound waves reverberate. [citation needed]
These periods are divided into three stages. The first stage occurs in the first 30 minutes of life; during this stage the infant is alert and responsive with heart rate peaking at 160-180 beats per minute and then stabilizes to a baseline rate of 100-120 beats per minute. Crackles upon auscultation and irregular respirations are a normal finding.
A souffle (English: / ˈ s uː f əl /) [a] is a vascular or cardiac murmur with a blowing quality when heard on auscultation.It is particularly used to describe vascular murmurs or transmitter heart sounds which occur during pregnancy, either from the uterus and breasts of the mother, or from the fetus.
Cardiotocography sound Schematic explanation of cardiotocography: heart rate (A) is calculated from fetal heart motion determined by ultrasound, and uterine contractions are measured by a tocodynamometer (B). These numbers are represented on a time scale with the help of a running piece of paper, producing a graphical representation.
Auscultation of the heart can be undertaken by medical professionals; Observation for secondary signs of circulatory failure such as edema or frothing from the mouth (indicative of congestive heart failure) ECG monitoring will allow the healthcare professional to help diagnose underlying heart conditions, including myocardial infarctions
At around 18 to 19 days after fertilisation, the heart begins to form. The heart begins to develop near the head of the embryo in the cardiogenic area. [1] Following cell signalling, two strands or cords begin to form in the cardiogenic region [1] As these form, a lumen develops within them, at which point, they are referred to as endocardial ...
Understanding Pediatric Heart Sounds 2nd edition (2003) by Steven Lehrer is a book and audio CD that guides the student through the skills of pediatric heart auscultation. It provides a complete overview of pediatric heart examination, anatomy, physiology, and pathology. The audio CD presents and explains normal and abnormal heart sounds. [1 ...
