Hybrids (a combination of breeds) are bred for either meat or egg production and the latter such as âBovan Goldlineâ (the type of hens used in most battery systems) can lay up to 320 eggs per year.
Electrocardiogram records the electrical activity of your heart. An EKG (or electrocardiogram) is an electrical representation of the cardiac activity as detected by surface electrodes placed in specific locations across the chest and extremities. These electrodes detect the electrical activity occurring in the heart and these are depicted as deflections of a line.
An ECG is a noninvasive, painless test with quick results. During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes your limbs. These sensors are usually left on for just a few minutes. Your doctor may discuss your results with you the same day as your electrocardiogram or at your next appointment.
