Ventricular Fibrillation

Ventilation/perfusion scans: Ventilation/perfusion scans, sometimes called a VQ (V=Ventilation, Q=perfusion) scan, is a way of identifying mismatched areas of blood and air supply to the lungs. It is primarily used to detect a pulmonary embolus. The perfusion part of the study uses a radioisotope tagged to the blood which shows where in the lungs the blood is perfusing. If the scan shows up any area missing a supply on the scans this means there is a blockage which is not allowing the blood to perfuse that part of the organ.

Correct placement enables the electric current to pass through the heart. • Press the AED 's "analyze" button. It will check to see if the person has a pulse and it will determine if a heart rhythm is shockable. • If a shock is needed, the AED will direct you to press the “Shock” button, then, it will delivers a highly effective defibrillation waveform to the heart.

Because of this inability to contract effectively, the rest of the vital organs receive inadequate amount of blood resulting to inadequate tissue perfusion. There are two types of left-sided HF; systolic and diastolic failure. Systolic failure happens when the left ventricle doesn’t have the enough energy to pump normally the blood to the general circulation. As for diastolic failure, the left ventricle loses the ability to fill itself with blood during resting period resulting to inadequate amount of blood to be pumped out to the circulation (Weinrauch, 2008). The diastolic dysfunction will eventually lead to right-sided heart failure.

(ii) The septum- this divides the right and left sides of the heart. (iii) Pacemaker- this sends out regular nervous impulses which travel along the axons of the pf the nerve cells out through the walls of the atria. It is located at the top right of the atrium.

The priorities are to detect intraoperative MI early, give effective treatment, and transfer the patient to ICU urgently for further cardiac care. [10] When myocardial ischemia is because of hypovolemia, hypotension should be primarily managed with IV fluids in the form of crystalloids or colloids and blood products. Inotropic support is required when there is no response to fluid administration. In this case myocardial ischemic changes were because of hypovolemic shock. Hence by correcting hypotension secondary to hypovolemia the myocardial ischemic changes were reversed.

Right Coronary Artery. When these arteries are narrowed, the blood flow and oxygen circulation is forced to stop causing your body to have less movement. This is a very dangerous disease due to the fact that when the blood clot occurs in the body, your heart may stop pumping blood and inhaling/exhaling oxygen which leads to certain heart attacks and/or death.

He proved that injured excitable biological tissues generated direct electrical currents. The experiment proved that electricity travels though nerves causing muscular contractions. By 1878, Wilhelm von Ziemssen discovered that the heart accelerates when periodic pulses of current are applied to the chest until its beat coincided with the external stimulus. John Alexander McWilliam then proposed in 1889 that sudden death in human beings is due to the heart beating irregularly or at the wrong rate.

Also, that it is a failure to the cardiovascular system in which the blood circulation decrease and eventually ceases. The second thing I learned, is that shock can be both cardiovascular and non-cardiovascular. Three major cardiovascular causes of shock are: poor pump function blood or fluid loss from blood vessels and poor vessel function.

A few ways hypertrophic cardiomyopathy can be diagnosed is by an echocardiogram which is an ultrasound of the heart that uses the ultrasound waves to create a visual picture of the heart, a radionuclide ventriculography test, which is a form of nuclear imaging where a gamma camera is used to create an image following the injection of a radioactive material, an EKG which stands for electrocardiogram, which is a noninvasive procedure where electrodes are placed on the skin and are connected in a specific order to a machine that when turned on measure the electrical activity all over the heart, and blood tests, urine tests, among others. Other ways you can be tested for HCM include a cardiac MRI, a CT scan, cardiac catheterization and a myocardial biopsy. Did you know that 1 in 500 people have hypertrophic cardiomyopathy, HCM? HCM has no cure, but can be relieved of symptoms by taking medications such as blood thinners, heart medication, and blood pressure medicine. HCM is also known under many other names such as Idiopathic Hypertrophic Subaortic Stenosis (IHSS), Asymmetric Septal Hypertrophy (ASH), Hypertrophic Nonobstructive Cardiomyopathy (HNC), Hypertrophic Obstructive Cardiomyopathy (HOC), and Familial Hypertrophic Cardiomyopathy (FHC).

During the test, you 'll be asked to blow into a large tube connected to a spirometer machine that measures how much air your lungs can hold and how quickly you can blow that air from your lungs. Spirometer test can detect COPD before you even experience any symptoms. Doctors may also use chest X-rays or other tests to help diagnose

There are numerous parts for cardiovascular ultrasound throughout potentially cardiotoxic cancer treatment regimens. Primarily, prior to potentially cardiotoxic chemotherapy, echocardiography can safeguard that patients do not already have diminished cardiac function. Subsequently, throughout chemotherapy, cardiovascular ultrasound can monitor ventricular function to eliminate chemotherapy-induced dysfunction. Preceding, the follow-up treatment, cardiovascular ultrasound can regulate new symptoms that are potentially caused from cardiac disease.
