April in the north is more apt to be rainy and slightly cooler than in the south. Itâs not as if Sicilians are heading to beaches in droves in April, but vacationers from colder climates might be tempted. In general, itâs usually a good idea to pack both a small umbrella or rain jacket with your sunglasses.
An arrhythmia (ah-RITH-me-ah) is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia (TAK-ih-KAR-de-ah). A heartbeat that is too slow is called bradycardia (bray-de-KAR-de-ah). Most arrhythmias are harmless, but some can be serious or even life threatening.
Cardiac arrhythmia, also known as cardiac dysrhythmia or irregular heartbeat, is a group of conditions in which the heartbeat is irregular, too fast, or too slow. A heart rate that is too fast â above 100 beats per minute in adults â is called tachycardia and a heart rate that is too slow â below 60 beats per minute â is called bradycardia.
