bradygastria

(brad-ē-gas'trē-ă),

Decreased rate of electrical pacemaker activity in the stomach, defined as less than 2 cycles/minute for at least 1 minute. Normal activity is defined as an electrical signal at a frequency of 2-4 cycles per minute using cutaneous electrogastrography. May be associated with nausea, gastroparesis, irritable bowel syndrome, and functional dyspepsia.

and 0.2-2.4 cpm range shows bradygastria, 0.07 Hz.-0.15 Hz.

There are two types of dysrhytmia, tachygastria and bradygastria. Tachygastria is an increase in the frequency of normal electrical activity of the stomach (3 cpm).

The high value of this area indicates bradygastria in patients at fasting state.

Dysrhythmia of the stomach includes tachygastria, bradygastria and arrhythmia (shown in table 1), which can be connected with the motor disorder of stomach and corresponding clinical symptoms together in (Shah and Rodriguez, 1999).
