During  Elastic Heart , the singer faced off to the side, a tulle shield obscuring most of her face underneath her signature blonde wig. Sia faced the audience for  Chandelier , but she still wore the same black visor, and a mime performed next to her to draw attention away from the singer.
A cardiac arrest is different to a heart attack. In a cardiac arrest the heart actually stops beating; whereas in a heart attack the heart normally continues to beat even though the blood supply to the heart is disrupted. heart attack occurs when the blood supply to part of the heart stops and thus causes a section of the heart muscle to begin to die; whereas a cardiac arrest occurs when the heart stops beating as a whole. There are various symptoms of a heart attack.
A cardiac arrest occurs when your heart suddenly stops beating. The heart functions through electrical pulses, and when those pulses are interrupted it can cause an irregular heartbeat or cardiac arrest. The cause of cardiac arrest is an electrical problem. It does not have anything to do with your arteriesâ functions. cardiac arrest occurs when your heart suddenly stops beating.
