In anatomy, the precordium or praecordium is the portion of the body over the heart and lower chest. [1] Defined anatomically, it is the area of the anterior chest wall over the heart. It is therefore usually on the left side, except in conditions like dextrocardia, where the individual's heart is on the right side. In such a case, the ...
Hyperdynamic precordium is a condition where the precordium (the area of the chest over the heart) moves too much (is hyper dynamic) due to some pathology of the heart. That means a forceful and hyperdynamic impulse ( large amplitude that terminates quickly) can be palpated during physical examination. [ 1 ]
In contrast, the precordial thump (hard blows given over the precordium with a closed fist to revert cardiac arrest) is a sanctioned procedure for emergency resuscitation by trained health professionals witnessing a monitored arrest when no equipment is at hand, endorsed by the latest guidelines of the International Liaison Committee on ...
The cooing dove murmur is a cardiac murmur with a musical quality (high pitched). Associated with aortic valve regurgitation (or mitral regurgitation before rupture of chordae). It is a diastolic murmur heard over the mid-precordium. [16] Continuous and Combined Systolic/Diastolic
The first heart sound, or S 1, forms the "lub" of "lub-dub" and is composed of components M 1 (mitral valve closure) and T 1 (tricuspid valve closure). Normally M 1 precedes T 1 slightly.
The mediastinum (from Medieval Latin: mediastinus, lit. 'midway'; [2] pl.: mediastina) is the central compartment of the thoracic cavity.Surrounded by loose connective tissue, it is a region that contains vital organs and structures within the thorax, namely the heart and its vessels, the esophagus, the trachea, the vagus, phrenic and cardiac nerves, the thoracic duct, the thymus and the lymph ...
New breast cancer guidelines suggest women over 40 should screen once every other year. The pivot can help reduce increased cancer rates, and especially better protect Black women.
Purkinje fibers also have the ability of firing at a rate of 20–40 beats per minute if upstream conduction or pacemaking ability is compromised. [9] In contrast, the SA node in normal state can fire at 60-100 beats per minute. [9] In short, they generate action potentials, but at a slower rate than the sinoatrial node. [9]
