Slow Heartbeat. Slow heartbeat (heart rate), called bradycardia, is an arrhythmia, or disorder of the heartâs rhythm. Each day, a normal heart beats about 100,000 times, at a rate anyÂ­where from 60 to 100 times a minute. Changes in heart rate caused by activity, diet, medications, and age are normal and common. Tachy-brady syndromeâ It is possible for the same person to have a slow heartbeat when the heart is in normal rhythm and periods of fast, irregular heartbeats (supraventricular tachycardias) at other times. 2  Sometimes, medications needed to control the fast heart rate can worsen the already slow heart rate.
They should be 40 to 50 feet away from all other trees. Allow an additional 15 to 20 feet between the live oak and your home, driveway or any other structure. This allows for roots that may extend beyond the adult tree's canopy.
Of course, they need enough room to breathe and get sufficient sun, which will vary from one cultivar to another. You can plant full-size apple trees 30 to 35 feet apart, semi-dwarf apple trees 20 to 25 feet apart and dwarfs as close as 15 to 20 feet apart. Just be sure to follow the proper pruning techniques for your species. Apples are also picky about their growing climate.
