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.
This treatment is called defibrillation (de-fib-ri-LA-shun). An ICD has wires with electrodes on the ends that connect to your heart chambers. The ICD will monitor your heart rhythm. If the device detects an irregular rhythm in your ventricles, it will use low-energy electrical pulses to restore a normal rhythm.
