The Candle Burning Guide - Center Burning Candles. Certain candles are designed to burn down the middle for different reasons, or a combination of different reasons. Candles with a unique finish, or unique burning characteristic, may burn down the middle in order to position the flame inside of the candle and illuminate from the inside out.
To find your maximum heart rate, subtract your age from 220. For example, if you are 40 years old, your maximum heart rate is 180 (that is, 220 - 40 = 180). Multiplying this by 50 percent and then 85 percent results in your target heart rate range of 90 to 153 beats per minute.
In general, patients with a signifcant bradycardia (less than 40 beats of the heart per minute), will usually have a very high systolic blood pressure as high as 220-240mmHg (the pressure during cardiac contraction), but a very low diastolic blood pressure as low as 40mmHg.
