Valuable conclusions on the effect of. loads and heating on concrete explosive spalling are shown in the paper. Keywrds: High-strength concrete, fire, explosive spalling, columns, heating rate, axial loads. INTRODUCTION. Concrete spalling under high temperatures is a major factor of reducing itâs fire resistance.
Abnormal heart rhythms are called arrhythmias. There are two kinds of cardioversion. Your doctor may give you one or more medicines to bring back your regular heartbeat. This is called pharmacologic (chemical) cardioversion. Doctors also restore regular rhythms by sending an electrical shock to the heart. This is called electrical cardioversion.
If the hospital determines you had an NSTEMI heart attack, doctors typically use one of two treatment strategies. One is called an âischemia-guided strategyâ, the other an âearly invasive strategyâ. Both may involve a test called cardiac catheterization to examine the inside of your heart.
