What else can I help you with?
Why is defibrillation not effective when there is a total absence of venticular electrical activity in the heart?
When there is no electrical activity in the heart (asystole), the AED won't start the heart as drugs are required to start the heart. The AED will only re-set the heart from abnormal electrical activity (such as V-Tach or V-Fib).
What is the medical term meaning procedure to assess the electrical activity of a patient's heart over a 24-hour period of normal activity?
The 24 ambulatory monitoring of the heart is called Holter monitoring
What is a cardiograph?
A cardiograph is an instrument designed to measure and record the electrical activity of the heart.
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 an electrocardiogram record the electrical activity of the heart?
Yeah, that's its prime objective. The leads placed on the limbs can measure the heart's electrical activity, as the voltages generated in the heart are readily transmitted through the body to the limbs.
Is electrical activity of the heart distal to proximal?
No, electrical activity in the heart moves from proximal to distal.
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.
Why does an ecg only trace recording of some electrical activity?
An ECG (electrocardiogram) only traces recording of electrical activity because it specifically measures the electrical signals generated by the heart as it contracts and relaxes. These signals are produced by the depolarization and repolarization of cardiac muscle cells, which initiate and coordinate heartbeats. While the ECG provides valuable information about the heart's rhythm, rate, and overall electrical function, it does not capture mechanical activity or other physiological processes occurring in the heart or body. Thus, it serves as a diagnostic tool primarily for assessing cardiac electrical activity.

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 is recording of electrical activity of the heart?
Recording of electrical activity of the heart is called an electrocardiogram (ECG). It is a non-invasive test that measures the electrical signals that control the heart's rhythm and can help diagnose heart conditions such as arrhythmias, heart attacks, and abnormal heart rhythms. It is performed by placing electrodes on the skin that detect the electrical impulses of the heart.
Any words containing graph at the end that has something to do with the human body?
Electrocardiograph: a device used to monitor the electrical activity of the heart. Phonocardiograph: an instrument used to record heart sounds and murmurs. Myocardiograph: a device for recording and analyzing the mechanical activity of the heart muscle.
What does ECG measure?
The electrical activity of the heart.
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
What is the medical term meaning specialist in the study of the electrical activity of the heart?
A Cardiologist is a Medical Specialist dealing with Heart problems. Cardiac electrophysiologists specialize in the electrical activity of the heart.
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.
What does an electrocardiogram (ECG) record about the heart's electrical activity?
An electrocardiogram (ECG) records the heart's electrical activity, showing the rhythm and strength of the heart's contractions. It can help diagnose heart conditions like arrhythmias and heart attacks.
