What sends electric currents to the heart causing it to beat at a steady pace?
The "cardiac pacemaker," a group of cells in the sinoatrial node of the right atrium of the heart, which generate regular electrical impulses causing the heart to beat. The rate of contraction is regulated up or down by nerve fibers originating from elsewhere in the body.
What do the electric charges of electrolytes in minerals help maintain?
Electric currents that keep your heart beating
What does the ecg wave tracing represent?
Electrical Activity of the Heart
An instrument for measuring heartbeats?
A stethoscope can be used to listen to the heart, the auscultations and valve sounds. There are many ways to "measure" a heart beat. The most effective tool is the ECG (electrocardiogram) which measures electrical activity of the heart. Because the electrical activity (electrical signals originating from the sino-atrial and atrio-ventricular nodes of the heart) is a direct indicator of the physical activity of the heart (contraction, relaxation, valve activity, etc) you can determine almost everything you need to know about the heart using an ECG, including its physical orientation within the mediastinum (sac containing the heart within the chest cavity). The time between each electrical impulse can be measured, thus giving elapsed time between each beat, and allowing you to determine how many times the heart contracts (beats) every minute - known as heart rate (HR). Presumably, this is what you mean by "measuring heartbeats", but an ECG is capable, as explained, of doing much more. Hope this helps, if you would like me to expand or go into more complex detail, let me know. Source: I am a Medical Student in the UK.
What is the role of the S-A node?
To generate the electrical impulse which triggers the onset of heart contraction
How may one find out if he or she has heart disease?
To detect heart disease, you should see your doctor who can perform an EKG test. An EKG test can test the electrical currents to your heart to assess if they are performing properly.
How do electrical currents help your hearts function well?
They are what tell your heart to beat.
What is a cardiograph?
A cardiograph is an instrument designed to measure and record the electrical activity of the heart.
What property of a heart muscle must be altered in order for an electrocardiogram to detect a problem?
The changes in electrical conductance is needed for the EKG to detect a problem.
Application of ecg?
An ECG is an electrocardiography. It is used to detect and record the electrical impulses of the heart. An ECG is non-invasive and may be used as a diagnostic tool to detect abnormalities.
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.
What is the medical term meaning Instrument for recording the force and form of heart movement?
An EKG or also known as ECG (electrocardiogram) machine measures the electrical impulses of the heart. "Cardio" means heart, and "gram" means measurement.electrocardiograph
The purpose of defibrillation is to?
It is to "restart" the heart's electrical conductivity and electrical rhythym. It, in general, sends out an electrical impulse to the heart to kickstart it.
What is measured by an EEG?
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.
What does a defibrillator actually do?
A defibrillator is a machine that is used to send strong electrical currents through two mental lined plates to help jump start a person's heart when they have flat lined.
Does a cardiogram show previous heart attacks?
An EKG is a graphical image of the electrical system of the heart. Heart attacks frequently cause changes in how electricity flows through the heart. Because of this, the changes can frequently be seen on an EKG after the heart attack has had time to heal.
Why you use galvanometer?
The galvanometer is an instrument for detecting electric current.It is an analog electromechanical actuator that produces a rotary deflection of some type of pointer in response to electric current flowing through its coil in a magnetic field.Galvanometers were first used to detect and measure electric currents.Sensitive galvanometers were used to detect signals from long submarine cables, and were used to discover the electrical activity of the heart and brain.
