What does depolarization of the heart mean?
It is a positive wave in the hearts muscle cells, the process of electrical discharge and the flow of electrical activity.
Does the electrical activity of the heart precede mechanical activity?
Yes. It is the electrical activity that stimulates the mechanical activity.
What does an electrocardiogram show?
an electrocardiogram records the electrical activity of the heart, with this you can see the rhythm of the heart and the way it is contracting. This is a great diagnostic tool for health care professionals.
Is electrical activity of the heart distal to proximal?
No, electrical activity in the heart moves from proximal to distal.
What does the ECG and EKG record?
ECG and EKG mean the same thing, and it records the hearts electrical activity on a 6 second strip. The physician can make a diagnosis by looking at the EKG print out. If a 12-Lead EKG is used, then all walls and function of the heart will be recorded.
What is the difference between an MRI and a EEG?
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.
Is alternating current artifacts part of the hearts electrical circuitry?
No it is not
What does ECG measure?
The electrical activity of the heart.
Action potential is an?
Explosion of electrical activity
The heart does not need to have electrical activity for defibrillation to work?
No, what defibrillation does is 'reorganize' chaotic electrical activity known as ventricular fibrillation or pulseless V-Tach.
What term is used to refer to the process of electrical discharge and the flow of electrical activity?
current
How do you record the electrical activity of the heart?
The electrical activity of the heart is recorded using an electrocardiogram (ECG or EKG) machine. This machine detects the electrical signals generated by the heart and produces a graphical representation of the heart's electrical activity called an ECG tracing. Electrodes are placed on the skin to capture these signals and can help diagnose heart conditions.
