The right answer is Electrocardiography (or Electrocardiogram).
In a typical plot, one can notice five characteristic waves. They are called P, Q, R, S and T. The illustration below shows what a normal electrocardiogram looks like:
* the P wave marks the depolarization during the contraction of the atria;
* the PR interval indicates the time required to transmit the electrical impulse of the sinus node of the atria to the ventricular muscles;
* the QRS complex marks depolarization and ventricular contraction;
* the QT interval corresponds to the global ventricular repolarization;
* T wave refers to the end of ventricular repolarization.

2. Next come the omnivores that eat a mixture of plants and herbivores. That's where humans rank, with a trophic level of 2.2. Above us are carnivores, such as foxes, that eat just herbivores. At the top of the scale are meat-eaters that don't have any predators themselves, such as polar bears and orca whales.
3. 25,000 square miles of forests provide habitats for many species and tourism opportunities for residents and visitors to the state. Forests are also essential to Florida's environmental health. Floridians from all walks of life are working together to preserve animal and plant habitats for future generations.
4. Abiotic factors in the Florida Keys are things like hurricanes, currents, sunlight, and water quality. Hurricanes occur in the Florida Keys about 13-16 percent. These violent storms can damage coral reefs because of high winds and large waves.
