If you are still unsure of the ant species after observing them in action, collect a few to examine under a hand lens, magnifier, or microscope, if you have one. The easiest way to capture and kill ants for examination is to fill a small vial, pill container, or jar with a small amount of ethanol or rubbing alcohol. Use the end of a soft cloth, or a brush, wet with alcohol to pick up the ants and drop them in your container.
When the heart does not get enough oxygen, either during a heart attack orâ¦ for whatever other reason, it tends to go into ventricular tachycardia or fibrillation, which can be reversed, but must be done quickly. In children, the most common cause of cardiac arrest is hypoxia and respiratory distress or arrest.
Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks do not lead to sudden cardiac arrest. But when sudden cardiac arrest occurs, heart attack is a common cause. Other heart conditions may also disrupt the heartâs rhythm and lead to sudden cardiac arrest. These include a thickened heart muscle (cardiomyopathy), heart failure, arrhythmias, particularly ventricular fibrillation, and long Q-T syndrome.
