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.
Realize that the shock often helps the patient feel better, (no more lightheadedness) and saves their life. Patients DO NOT always have to have their rapid heart rhythm corrected with a shock, however. Often, the abnormal rhythm can be corrected with painless and imperceptible pacing therapy.
