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 ...
The patient is positioned in the supine position tilted up at 45 degrees if the patient can tolerate this. The head should rest on a pillow and the arms by their sides. The level of the jugular venous pressure (JVP) should only be commented on in this position as flatter or steeper angles lead to artificially elevated or reduced level respectively.
This is due to the position of the heart within the chest: the right ventricle is most anterior (closest to the chest wall). Hypertrophy of the right side of the heart will occur when the right side of the heart chronically contracts against higher pressure.
The cardiac impulse is the vibration resulting from the heart rotating, moving forward, and striking against the chest wall during systole. The PMI is not the apex of the heart but is on the precordium not far from it. Another theory for the occurrence of the PMI is the early systolic contraction of the longitudinal fibers of the left ventricle ...
"Sleeping on the right side can be beneficial for people with heart failure or certain cardiac arrhythmias," Dr. Salazar says. "Studies have found that lying on the left side alters the heart's ...
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 ]
The good news, though, is that pain on the right side of the body alone without any other symptoms usually isn't something to worry about—whew!—even though several organs could be affected ...
Impact energies of at least 50 joules (37 foot-pounds force) may cause cardiac arrest when applied at the right time and location of the precordium of an adult. [11] The 50-joule threshold, however, can be considerably lower when the victim's heart is under ischemic conditions, such as in coronary artery insufficiency. [11]
