What else can I help you with?
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.
Is alternating current artifacts part of the hearts electrical circuitry?
No, alternating current artifacts are not part of the heart's natural electrical circuitry. The heart's electrical system is driven by specialized cells that generate and propagate electrical signals to coordinate the heartbeats. External sources of alternating current can interfere with the heart's electrical activity and cause disruptions or abnormalities in the heart rhythm.
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.
What does an electrocardiogram record about the heart's electrical activity?
An electrocardiogram (ECG) records the heart's electrical activity, showing the heart's rhythm and any abnormalities in the heart's electrical system.
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.
How do you record the electrical activity of the heart?
You record the electrical activity of the heart with a machine called ECG machine. Leads are attached to the limbs and then you have chest leads put on the chest wall in different positions to produce a tracing of the electrical activity called electrocardiograph
