Weather in Italy in April. April in the northern hemisphere is turning its head firmly toward summer, but that doesnât mean itâs all sunny skies. In Italy, April weather can be pretty unpredictable â remember those famous âApril showersâ from the childrensâ rhyme? â though itâs typically far sunnier than it is wet.
Arrhythmia monitoring refers to tests physicians use to identify the type and the cause of irregular heart rhythms. Many arrhythmias occur infrequently, so to record the heart's electrical activity under real-world conditions, physicians use continuous monitor recording, also called ambulatory electrocardiography.
An arrhythmia is an abnormality in the heart's rhythm, or heartbeat pattern. The heartbeat can be too slow, too fast, have extra beats, skip a beat, or otherwise beat irregularly. Arrhythmias are deviations from the normal cadence of the heartbeat, which cause the heart to pump improperly. The normal heartbeat starts in the right atrium, where the heart's natural pacemaker (the sinus node) sends an electrical signal to the center of the heart to the atrioventricular node.
