temp pacemakertPM
Temporary cardiac pacing is an intervention that helps the heartbeat get back to a normal pace if it has been temporarily out of rhythm. In temporary cardiac pacing, wires are inserted through the chest (during heart surgery), or a large vein in the groin or neck, and are directly connected to the heart. cardiovascular Oct 5, 2019, 12:59 PM HirotoShishido

Monday diseasedue to prolonged nitrate exposure
symptoms develop on Monday with re-exposure, due to loss of tolerance. The most severe consequence occurs when compensatory vasoconstriction is unopposed in critical areas such as the coronary vessels, leading to nonatherosclerotic-related cardiac ischemia cardiovascularpharmacology Oct 1, 2019, 1:27 AM HirotoShishido
