Biomes. The two main types of biome are terrestrial (land-based) and aquatic (water-based). The easiest to discuss are the terrestrial biomes since they have a more definite boundary. The different climates of the Earth are governed by their average annual precipitation and temperature.
An electrocardiogram (ECG or EKG) test. An electrocardiogram (ECG or EKG) is a routine test that is used to look at the electrical activity of the heartbeat. An electrocardiogram can tell your doctor a lot about your heart and how it is working.
ECG is the recording of the electrical activity of the heart from electrodes placed on the surface of the body. Many cardiac arrhythmias are episodic in nature, especially in the cat. This means that some rhythm or conduction abnormalities can be missed during a standard 1-minute ECG recording.
