Experiment Results Predict Question: Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction velocity will be the same in both fibers. Stop & Think Questions: 3. Note the

relax? T wave 11. Describe the pathway of conduction from the atria to the ventricles and correlate this conduction with the ECG waves. The SA node is designated as the pacemaker of the heart. From the SA node‚ the electrical impulse spreads through interatrial tracts that spread the electrical impulse through the right and left atria and therefore cause atrial depolarization. As a result‚ a P-wave is observed. After the atria depolarize‚ the electrical impulse spreads through the internodal tracts and

Electrical impulses travel from the natural pacemaker through the atria then pass through a filter before running down specialized fibers that activate the ventricles. The atria are above the ventricles‚ thus the term supraventricular. The term tachycardia refers to a rapid heartbeat of over 100 beats per minute. Supraventricular tachycardia then is a rapid rhythm of the heart that begins in the upper chambers. When patients experience change in the normal sequence of electrical impulses and an abnormal

Introduction: This case study discusses the management of a 68 year old male who presented with chest palpitations secondary to rapid atrial fibrillation. Atrial fibrillation is a common cardiac arrhythmia with serious complications if not treated correctly. This essay will discuss the initial clinical presentation of the patient and examine the management and outcome of the interventions applied. The significance of atrial fibrillation including its pathophysiology and aetiology will also be discussed

The louder the sound‚ the more energy that is being carried. electrical energy: Energy created by the movement of the electrons in an atom‚ the negatively charged particles. Because the electrons are moving around so quickly we have electricity. 1. Name one similarity between convection‚ conduction and radiation. They are all

Normal Sinus Rhythm (NSR)‚ Sinus Bradycardia‚ Sinus Tachycardia‚ and Sinus Arrhythmia. Normal Sinus Rhythm is fairly easy to understand due to the pacemaker impulse‚ which originates in the sinus node and travels through the normal conduction pathways within normal time frames. Because the pacemaker originates in the sinus node and the conduction is normal‚ the P waves are uniform and will have a P wave for each QRS complex. Due to it being a Normal Sinus Rhythm the heart rate has to be a rate of 60

“Heat Conduction” Introduction Thermal conduction is a mode of heat or energy transfer that occurs in a solid or fluid due to the presence of temperature gradient. It is the transfer of energy from the more energetic particles to the adjacent less energetic particles in the form of interactions between the particles. Simply put‚ it is defined as heat transferred by molecules that travel a very short distance before colliding with another molecule and exchanging energy. Theory There are
