In a Presidential System, the head of state and head of government tends to be the same person. In a Parliamentary System, minority groups can form third, fourth, and fifth parties and have much more influence in government than in a Presidential System where third parties are marginalized (many complexities here).
Electromyography (EMG) uses small needle electrodes to measure the electrical currents in a muscle as it contracts. While an EMG canât definitively diagnose metabolic disease, it can be used to rule out a number of other types of neuromuscular disease that cause similar patterns of weakness.
An ECG measures electrical activity of the heart. An EEG evaluates electrical impulses of the brain and nerves. An ECG is used to detect heart ailments in patients who have suffered heart attacks or abnormal heart rates. An EEG is a staple test for patients with seizures, tumors, coma or nervous disorders.
