Overview. Your pulse is the vibration of blood as your heart pumps it through your arteries. You can feel your pulse by placing your fingers over a large artery that lies close to your skin. The ...
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. The cardiac impulse is the vibration resulting from the heart ...
The femoral artery is tasked with delivering blood to your lower limbs and part of the anterior abdominal wall. This artery begins near your groin, in your upper thigh, and follows down your leg ...
The heart has three layers. They are the: Epicardium: This thin membrane is the outer-most layer of the heart. Myocardium: This thick layer is the muscle that contracts to pump and propel blood ...
Measuring the pulse rate is therefore a convenient way to estimate the heart rate. Pulse deficit is a condition in which a person has a difference between their pulse rate and heart rate. It can be observed by simultaneous palpation at the radial artery and auscultation using a stethoscope at the PMI, near the heart apex, for example. Typically ...
Graphical representation of the electrical conduction system of the heart that maintains the heart rate in the cardiac cycle. Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum.
Cross-section. The chambers of the heart operate as a ‘double-pump’ system for the body’s circulation. In coordination with valves, the chambers work to keep blood flowing in the proper ...
