What instrument is used to detect electrical currents from the heart?
An electrocardiogram (ECG or EKG) is the instrument used to detect electrical currents from the heart. This test records the electrical activity of the heart over a period of time, typically a few minutes, to assess its health and function.
What rhythm do the P waves represent?
The P waves represent the electrical activity that causes the atria to contract in the heart. They occur before the QRS complex on an electrocardiogram (EKG) and signify the depolarization of the atria.
How do EKG machine leads work?
EKG machine leads are electrodes attached to the patient's skin to measure the electrical signals produced by the heart. The leads pick up these signals and transmit them to the EKG machine, which then displays them as a graph that represents the heart's electrical activity. Different lead placements provide different views of the heart's electrical activity.
What is a record of the heart electricity?
A record of the heart's electrical activity is called an electrocardiogram (ECG or EKG). This non-invasive test measures the electrical signals that control the heart's rhythm and can help diagnose various heart conditions. The ECG shows the timing and strength of electrical impulses as they move through different parts of the heart.
How do you measure pause on the ekg?
A pause on an EKG can be measured by identifying the absence of electrical activity between consecutive heartbeats. The duration of a pause can be determined by measuring the distance between the last electrical activity before the pause and the first activity after the pause. It is important to note the presence and length of pauses as they can indicate underlying heart rhythm disturbances.
