What is the fuction of the cardiac cell?
Cardiac muscle cells are the cells that make up the cardiac muscle and help to pump blood through your heart. Each of these cells contain myofibrils which are the contractile units of muscle cells. These cells have the ability to produce ATP quickly, making them resistant to fatigue.
What are the potential causes of biphasic T wave changes on an electrocardiogram?
Potential causes of biphasic T wave changes on an electrocardiogram include myocardial ischemia, electrolyte imbalances, drug effects, and certain cardiac conditions such as hypertrophic cardiomyopathy.
Artery easiest to access during low cardiac output?
The radial artery is often the easiest to access during low cardiac output because it is superficial and has good collateral circulation. It is also less affected by changes in peripheral vascular resistance compared to other arteries.
During an action potential, what happens to the neuron's electrical charge?
During an action potential, the neuron's electrical charge rapidly changes from negative to positive, allowing for the transmission of signals along the neuron.
What is normal systemic vascular resistance?
Normal systemic vascular resistance ranges between 800-1400 dynes·sec/cm^5 in adults. It is an important measure of the resistance the heart must overcome to pump blood through the systemic circulation. Changes in systemic vascular resistance can impact blood pressure and cardiac output.
An electrocardiogram is a recording of electrical changes occurring in the myocardium during what?
Cardiac cycle
What is the medical term meaning electrical changes in the heart muscles?
There is no single term but a good sentance would be "cardiac conductance disorder"
What is the graph detecting the electrical changes in the heart as it beats?
An electrocardiogram is a graphical recording of the cardiac cycle produced by an electrocardiograph monitoring heart beats.

ECG Machine is the process of producing an electrocardiogram( ECG or EKG), a recording of the heart's electrical activity. It's an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle( heartbeat). Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including cardiac rhythm disturbances( such as atrial fibrillation and ventricular tachycardia), inadequate coronary artery blood flow( such as myocardial ischemia and myocardial infarction), and electrolyte disturbances( such as hypokalemia and hyperkalemia).
What is the significance of the t wave?
The T wave represents ventricular repolarization on an electrocardiogram (ECG). It shows the recovery of the heart's electrical activity and is important in assessing heart function and identifying potential cardiac abnormalities. Changes in the T wave can indicate electrolyte imbalances, ischemia, or other cardiac conditions.
A toaster changes electrical energy to?
A toaster changes electrical energy to heat.
What is the t wave?
The T wave is a component of the electrical activity of the heart that represents ventricular repolarization. It occurs after the QRS complex on an electrocardiogram (ECG) and indicates the resetting of the heart's electrical system in preparation for the next heartbeat. Changes in the T wave can indicate various cardiac conditions.
What has the author A H Weston written?
A. H. Weston has written: 'The use of drugs to investigate the association between tension changes and changes in Adenosine Triphosphate, creating phosphate and oxygen consumption in smooth and cardiac muscle'
What is the just noticeable difference in psychology?
The just noticeable difference (JND) in psychology refers to the smallest detectable difference between two stimuli that a person can perceive. It helps to understand how sensitive someone's sensory system is to changes in stimuli, such as differences in brightness, weight, or sound. The JND is an important concept in psychophysics and perception research.
What does a segment on an electrocardiograph tracing indicate?
A segment on an electrocardiograph (ECG) tracing represents a specific period of electrical activity in the heart. It typically refers to the flat portions between waves, such as the PR segment or ST segment, and indicates the time taken for electrical impulses to travel through the heart's conduction system. These segments are crucial for assessing the heart's electrical stability and diagnosing various cardiac conditions. Changes in segments can indicate issues like ischemia or arrhythmias.
What are electrical messages called?
Electrical messages in the body are called action potentials. These are rapid changes in the electrical voltage across a nerve cell membrane that allow for the transmission of signals between cells.
What can you say about the amplitude of various waves in different cardiac cycles?
In a cardiac cycle, the amplitude of the waves, such as the P wave, QRS complex, and T wave, can vary depending on factors like the strength of the electrical impulses generated by the heart, the conductivity of the cardiac tissue, and the lead placement during an electrocardiogram (ECG). Changes in wave amplitudes may indicate abnormalities in the heart's electrical activity and can help in diagnosing conditions like arrhythmias or heart attacks. Monitoring these wave amplitudes can provide valuable information about the heart's functioning.
