Is the term for a delay or interruption in conduction of the electrical impulse in the myocardium?

∙ 13y ago
The term for a delay or interruption in conduction of the electrical impulse in the myocardium is "heart block." Heart blocks can range from first-degree (mildest) to third-degree (most severe) based on the extent of conduction disruption in the heart's electrical system.

How can i trace an impulse through the myocardium?
You can trace an impulse through the myocardium by using various techniques such as electrocardiography (ECG), which records the electrical activity of the heart. Another method is by using invasive procedures like cardiac catheterization or electrophysiological studies, which can directly measure electrical activity within the heart. These methods help to visualize the propagation of the impulse through different regions of the myocardium.
What is the difference between impulse conduction and transmission?
Impulse conduction refers to the propagation of action potentials along a single neuron or muscle fiber. Impulse transmission involves the transfer of action potentials from one neuron to another across a synapse. In summary, conduction occurs within a single cell, while transmission occurs between cells.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
The depressant effect of alcohol does not interfere with the conduction of the electrical impulse of the heartbeat?
Although alcohol is a depressant that can slow down the central nervous system, including heart rate, it does not directly interfere with the conduction of the electrical impulse of the heartbeat. However, excessive alcohol consumption can lead to irregular heartbeats, known as arrhythmias, due to electrolyte imbalances and other metabolic factors. If someone experiences abnormal heart rhythms while drinking, they should seek medical help.
Functional connection between two neurons is a?
functional connection between two neurons is the transmission of electrical signals from one neuron to another through a synapse. When an electrical impulse reaches the axon terminal of the pre-synaptic neuron, it triggers the release of neurotransmitters into the synaptic cleft. These neurotransmitters then bind to receptors on the post-synaptic neuron, allowing the electrical signal to be transmitted and continue the communication between neurons.

Is the velocity of a nerve impulse greater than electrical conduction's?
yes

When does the human heart rest?
The electrical impulse reaches all the muscle tissue in the ventricles, and the ventricles contract. This electrical conduction pattern occurs approx. every 0.8 seconds.
In coronary conduction the electrical impulse is released at what level of the coronary electrical system?
With Wolff-Parkinson-White Syndrome, the heart has an extra nerve, or "accessory pathway" that electrically connects the _____ to the _____.
What is the membrane of a nerve cell is comprised of?
Its main function is to propagate the action potential (the 'impulse') along the length of the axon.
What tissue type functions in impulse conduction?
Nervous tissue functions in impulse conduction. It consists of neurons that transmit electrical signals or impulses throughout the body. The specialized structure of neurons, including dendrites, axons, and synapses, enables them to rapidly transmit information.
What is impulse conduction?
Party of nervous
What is impulse conduction is fastest in neurons?
Impulses that travel along myelinated neurons are the fastest.
The speed at which a neural impulse travels is increased when the axon is encased by an?
insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.
How does body temperature affect the conduction speed of an electrical impulse?
An increase in body temperature can lead to faster conduction speed of electrical impulses in the body due to improved nerve function and reduced resistance in the nerve fibers. Conversely, a decrease in body temperature can slow down conduction speed as nerve function is impaired.
