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.

The amount of space you have and how dense you want your screen will determine the number of rows you plant. Spacing between rows is based on crown width, but at a minimum try to avoid root crowding by setting at least 12 to 24 apart measuring from the center of the plant.
