Again, most blocks are sixteen inches long. Thus, if you use a factor of .75, you will find how many block to use in one course. For a 100 feet long wall, you would multiply 100 x .75 = 75.ost blocks are nominal eight inches high. So, if you use the factor of 1.5, you will find the amount of courses. In the case of a 16 feet high wall, multiply 1.5 x 16 = 24. It takes 24 courses to achieve 16 feet.
EKG (Electrocardiogram) An EKG is a simple, painless test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular). An EKG also records the strength and timing of electrical signals as they pass through the heart.
The following are just a few of the diagnostic tests that have been used or are being used to further understand and identify cardiovascular disease. For more specific information, consult your cardiologist or other health care provider: Electrocardiogram (ECG). A test that records the electrical activity of the heart, shows abnormal rhythms (arrhythmias), and can sometimes detect heart muscle damage. Stress test (also called treadmill or exercise ECG).
