What magnifies the heart electrical signal so that it can be recorded?
amplifier
Does heart work alone?
no the heart resives an electrical signal from the brain causing the mucle to flex
Why there is a delay between the heart beat in the blood pressure recording and the heart beat in the electrical ECG?
the ECG signal is traveling faster than the pressure recording wave.
What does left atrial abnormality in ecg mean?
An electrocardiogram (ECG) records the electrical activity of the heart. It produces a trace of the heart working and the trace for an individual can be compared to that of a normal, healthy heart. A left atrial abnormality means that the ECG for the heart in question shows that there is something wrong with the electrical signal relating to the heart's left atrium.The left atrium is one of four chambers in the heart. It receives oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve.You need to get the doctor to explain the CAUSE of the anomalous electrical signal.
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).

Can you die from a punch in the heart?
Yes. If the heart receives a direct blow that is hard enough, the impact can disrupt the electrical signal and stop the normal rhythm of the heart.
What does a pacemaker control in the heart?
A pacemaker sends electrical shocks to the heart to beat it at a particular speed. It pulsates the heart at a set rate (eg. 60bpm) to help those who are have a slower than normal heartbeat.
What component of an IRS creates an electrical charge?
What component of ied creates electrical charge
What signal is the electrical equivalent of message signal?
Modulating Signal,

What creates heart rate?
Heart rate is simply the number of times that the heart beats per minute. This is generated by the "pacemaker" of the body which is the signal sent from the brain to the heart's sinoatrial (SA) node. This causes the initiation of contraction of the cardiac muscle which spreads across the heart to contract the atria and ventricles in a rhythmic fashion. The number of times this signal is sent from the brain to the heart gives the heart rate.
How audio signal convert into electrical signal?
microphone............
What is different between optical fiber signal and electrical signal?
A fiber optical signal is based on the transfer of photons, while an electrical signal is based on the transfer of electrons.
What is a echocardiograph?
an echocardiograph is a test done to see if the heart is beating correctly, or if there are any irregularities with the heartbeat. It is done by placing a number of electrical sensors or "leads" on various parts of the body and measuring the electrical signal at each point. These electrical signals tell us if the heart muscle cells are polarizing and depolarizing the way they should be
