An ECG or EKG is a recording of the electrical activity of the heart. An echocardiogram is an ultrasound recording of the heart and its blood flow.
No, the brain continues to produce electrical activity while a person is asleep. In fact, different stages of sleep are associated with distinct patterns of brain wave activity that can be measured using an electroencephalogram (EEG).
Yes. It is the electrical activity that stimulates the mechanical activity.
Echo is associated with Greek mythology. She was a mountain nymph, though it is not known from which area of Greece.
The straight line on an EKG is called the isoelectric line. It represents the baseline electrical activity of the heart when there is no depolarization or repolarization occurring. Deviations from this line indicate electrical activity associated with heartbeats, such as P waves, QRS complexes, and T waves.
No, electrical activity in the heart moves from proximal to distal.
Echo wasn't a goddess. She was a nymph. A nymph is a lesser goddess usually associated with nature and its wonders; thus Echo became the 'goddess' of echoes with her curse.
EEG is Electroencephalograph. In plain English - Electrical Brain wave measurer. It measures electric currents in the brain. There are various currents associated with brain activity, with Greek letter names. eg. Alpha Waves.
a neurological disorder marked by sudden recurrent episodes of sensory disturbance, loss of consciousness, or convulsions, associated with abnormal electrical activity in the brain.
Both measure electrical activity -- the ECG in the heart and the EEG in the brain.An EEG is an electroencephalogram and an ECG also known as an EKG is an electrocardiogram. An EEG records brainwave/electrical activity. An ECG records the electrical activity that the heart produces.
An electrocardiogram (ECG) records the heart's electrical activity, showing the heart's rhythm and any abnormalities in the heart's electrical system.
The stress allows doctors to view electrical activity in the heart while it is working very hard. The echo cardiogram allows doctors to actually see what happens in the heart and the heart valves while the heart is working hard. These tests are used diagnose heart trouble or to rule out heart trouble as the cause of particular symptoms.
