the study of the anatomy, normal functions, and disorders of the heart. The medical field dedicated to diagnosing and treating diseases of the heart and cardiovascular system. See Interventional cardiology, Nuclear cardiology.. APC, or atrial premature complex (or beat) is a beat that arise in the atria of the heart from outside the normal mechanism of heartbeats. It's very common and doesn't portend any bad prognosis. It increase with age, smoking, coffee intake, alcohol intake, and stress, and also with heart and lung disease.
A nanometer is a unit of spatial measurement that is 10-9 meter, or one billionth of a meter. It is commonly used in nanotechnology, the building of extremely small machines. This was last updated in September 2005.
While ammeters are used to measure the currents, the voltmeter is used to measure the voltage. Both the devices are different in terms of functionality and circuit placement. An ammeter is an instrument that is used to measure the currents in a circuit.The currents are measured in amperes (A). Instruments used to measure smaller currents, in the milliampere or microampere range, are designated as milliammeters or microammeters.ultimeters can also be utilized in place of both ammeters and voltmeters. A multimeter is an instrument that can be used to measure both, currents as well as voltages. It can also perform as ohmmeters, a device used to measure resistance. Multimeters are available in analog or digital format. Ammeter.
