Electrical conduction system of the heart

of blood through the heart, out to the body, and back to the heart. Start at the inferior/superior vena cava. Include what kind of blood (oxygenated/deoxygenated) is circulating. Use correct terminology and anatomical terms. You may draw a diagram and use colored pencil/marker/crayon/pen to illustrate. • Deoxygenate Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. • blood flows from

This

Electrocardiogram, or ECG or EKG, is a recording of the hearts electrical activity as a graph over a period of time, as detected by electrodes attached to the outer surface of the skin and recorded by a device external of the body”(Boundless). The graph of an ECG can identify various things initiated by the heart, such as its rate, rhythm, a decrease in blood flow, and a possible enlargement. For a healthy individual, a typical ECG shows the whole cardiac cycle or heart beat which includes a P wave (Atrial depolarization)

Bradycardia Workflow Process Sinus bradycardia is defined as a heart rate of less than 60bpm in conjunction with normal sinus rhythm. A bradyarrhythmia, on the other hand has a disturbance in cardiac conduction with rate of less then 60bpm (Swift, 2013). Intrinsic and extrinsic etiologies contribute to bradycardia. Intrinsic causes relate to abnormalities in the conduction system, where extrinsic causes include: increase vagal tone, electrolyte imbalance, hypoxia, hypothermia

electrocardiograph to help us determine the heart electrical activity. As well as, to observe how exercise and different body positions(conditions) can affect the activity of the heart. Introduction Trained professionals can look at the EKG tracing and determine if the heart is normal or if the heart is abnormal. “An ECG records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract” (Kenny, 2015). There are two

of severity. There are heart conditions that you are able to live with and manage on a daily basis and those that require immediate attention. Atrial Fibrillation is one of the more frequently seen types of dysrhythmias (NIH, 2011). The best way to diagnosis a heart condition is by reading a cardiac strip (Ignatavicius &Workman, 2013). Cardiac strips play an chief part in the nursing world allowing the nurse and other trained medical professionals to interpret what the heart is doing. In a normal

Running head: CARDIAC CONDUCTION CYCLE AND OUTPUT 1 Cardiac conduction cycle and Output July 30, 2014CARDIAC CONDUCTION CYCLE AND OUTPUT 2 Cardiac conduction cycle and output Cardiac conduction ensures that cardiac chambers are stimulated to contract in a coordinated manner, which makes the heart an effective pump. The autorhythmic fibers are self-excitable; they repeatedly and rhythmically generate action potentials that trigger heart contractions. They even continue

The heart has distinguished components that allow the pathway of electrical conduction to travel through the heart in order to effectively pump blood through the body. The electrical impulse initiates in the Sinoatrial node (SA node), which is located in the posterior wall of the right atrium, near the superior vena cava. It is also known as being the physiologic pacemaker of the heart and has an intrinsic firing rate of 60-100 impulses/min. From the SA node, the electrical impulse flows directly

All cells must contract in a specific sequence. This sequence is determined by the pathway known as the conduction system. 2. Cardiac cells are connective and autorhythmic. What does this mean? Connective cells, action potentials, (excitatory signals) can propagate from
