A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together. Arrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias -- less than 50 beats per minute).Arrhythmias can also occur with rapid heart rates (called tachyarrhythmias -- faster than 100 beats per minute).rrhythmias can occur with a normal heart rate, or with heart rates that are slow (called bradyarrhythmias -- less than 50 beats per minute).

Galapagos Islands. Visting the Galapagos Islands is a must for most people looking for Ecuador Tours. The Galapagos, which are part of Ecuador, sit in the Pacific Ocean about 1000 km (620 miles) west of South America. Because the islands were never connected to the mainland, many species of plants and animals are unique to the Galapagos. In 1835, the young naturalist Charles Darwin, arrived on the islands.
The Galapagos Archipelago is a cluster of some 13 volcanic islands and associated islets and rocks located just under the equator, about 600 miles (1000km) west of Ecuador in South America.The oldest of the islands are about 4 million years old and the youngest are still in the process of being formed.he Galapagos Archipelago is a cluster of some 13 volcanic islands and associated islets and rocks located just under the equator, about 600 miles (1000km) west of Ecuador in South America.
