Your doctor will diagnose CHD based on your medical and family histories, your risk factors, a physical exam, and the results from tests and procedures. The following tests may be done.
• Coronary angiography (angiogram) is a procedure that uses contrast dye and x-rays to look at the lumen of your arteries. It can show if there is plaque accumulation and the degree of narrowing. Doctors use this procedure to diagnose heart diseases after chest pain, sudden cardiac arrest or abnormal results from other heart tests such as an EKG or a stress test.

• Cardiac CT (computed tomography) scan is a painless imaging test using a large donut-shaped machine that uses x-rays to take detailed pictures of your heart and its blood vessels. Computers combine …show more content…

It can reveal signs of heart failure, as well as lung disorders and other causes of symptoms not related to heart disease.

• Echocardiography, or “echo”, is a painless ultrasound of the heart to create dynamic pictures of your heart to show the shape and size of your heart as well as how well your heart's chambers and valves are working.

• Electrocardiogram also known as “EKG” or “ECG” detects and records your heart's electrical activity, showing how fast your heart is beating and whether its rhythm is steady or irregular. Electrodes (patches that have sensors) are applied to the skin on your chest, arms, and legs with wires connecting the electrodes to a machine that records your heart's electrical activity.

• Stress testing is typically done on a treadmill and is used by doctors to measure heart activity during exercise. It can help diagnose CAD and check for other problems, including heart valve disease and heart failure. An EKG would be done along with blood measurement monitoring. . If you are unable to exercise, drugs would be given to make your heart work hard and beat fast. A radioactive drug will be administered and special cameras would be used to take picture of your

  • Various Ekg readings

    There are several different heart problems that show up as an abnormal EKG reading. For example, a heart block can occur when there is a delay in the signals coming from the SA node, AV node, or the Purkinje fibers. However, clinically the term heart block is used to refer to an AV block. This delays or completely stops communication between the atria and the ventricles. AV block is shown on the EKG as a delayed or prolonged PR interval. The P wave represents the activity in the atria, and the QRS complex represents ventricular activity. This is why the PR interval shows the signal delay from the AV node. There are three degrees of severity, and if the delay is greater than .2 seconds it is classified as first degree. Second degree is classified by several regularly spaced P waves before each QRS complex. Third degree can be shown by P waves that have no spacing relationship to the QRS complex. Another type of blockage is bundle branch block. This is caused by a blockage in the bundle of His, creating a delay in the electrical signals traveling down the bundle branches to reach the ventricles. This results in a slowed heart beat, or brachycardia. On an EKG reading this is shown as a prolonged QRS complex. A normal QRS is about .8-.12 seconds, and anything longer is considered bundle branch block. Another type of abnormal EKG reading is atrial fibrillation, when the atria contracts very quickly. On the EKG this is shown by no clear P waves, only many small fibrillating waves, and no PR interval to measure. This results in a rapid and irregular heartbeat. On the other hand, ventricular fibrillation is much more serious and can cause sudden death if not treated by electrical defibrillation.

    In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays

    A cardiac assessment: Listen to heart sounds listening for extra heart sounds, fast heartbeat, and monitor EKG looking for dysthymias. Assess vitals especially BP, BP should be kept low in heart failure patients to put less stress on the heart. Assess the patient for edema as a result of fluid retention. Listen for crackles in the lungs due to fluid built up. Watch I&O’s and weight the patient to assess for edema, ask about activity intolerance. Assess for changes in mental status, cool extremities, pale or cyanotic, fatigue, and JVD (Indications of poor perfusion) (Ignatavicius &Workman, p.756).

    In this article, it tells how an EKG scan is on grid paper and each small block, which is one millimeter (mm) long, represents 0.04 seconds and each larger box, which is five millimeters long, represents 0.2 seconds. On a EKG scan, the voltage of the heart is measured in millivolts (mV) along the y-axis. On the scan grid, ten millimeters is equal to one millivolt. According to this source, in order to calculate the beats per minute (BPM), one divides the number of number of large boxes between each heart beat (QRS wave) in 300 small boxes. However, that used for a more consistent and steady heart rate. For a more varied and irregular rhythm, one has to count the number of QRS waves in six seconds and then multiply that number by ten. For an example, if there are eight QRS waves, then the estimated heart rate would be 80

  • Discussion of Aortic Dissection

    ...ers. Numerous signs and symptoms occur with an aortic dissection, making it very difficult to diagnose. Chest x-ray and chest and abdomen CT angiograms are the two most common tests performed to confirm a diagnosis, with CT angiogram being the modality of choice. If the patient survives the initial onset of an aortic dissection long enough surgical repair may be done. Surgical repair is very risky and does not have a high success rate, however, if surgery proves to be successful a patient’s prognosis greatly increases after 30 days. Perhaps the next time one is faced with the familiar imagery of a man grasping his chest and collapsing due to “heart disease,” instead of assuming the man suffered from the usual heart attack, one will remember that there are countless conditions that heart disease encompasses, and that aortic dissection remains one of the most deadly.

    These heart tests are known as echocardiograms. For example, these evaluate different aspects of the heart, such as chamber size, valve function, and blood flow. One may even do tests such as Holter monitoring and stress testing. This job requires you to be responsible for recording medical history, preparing the patients, maintaining the equipment, and performing the procedures. After you perform the procedure on the patient, you must then discuss the results with the doctor. Strong communication skills are a key characteristic that a physician should always possess in this field of duty.

  • What Stress Is

    2588 Words  | 6 Pages

    Stress means different things to different people and stress effects people in different ways. Some people think stress is something that happens to them such as an injury or a promotion and others think that stress is what happens to our mind, body and behaviors in response to an event. While stress does involve events and how one responds to them these are not the critical factors, but our thoughts about the situation in which we are involved are the critical factors. Essentially, stress exists whenever homeostasis is disturbed or cannot be maintained (Stress and the Social System Course Guide, 2013). Homeostasis refers to the body's ability to keep the internal chemical and physical environments constant. As your body begins to react to stress several changes occur. These changes include increased heart rate, blood pressure and secretion of stimulatory hormones. Ones body prepares itself in stressful situations to either stand ground and fight or to flee from the situation. Walter Cannon called this stressful reaction the fight-or-flight response (Greenberg, 2012).

    A traditional echocardiogram uses sound waves to produce images of the heart. In this procedure, a radiologist uses a transducer (a transducer is an electrical device that converts a signal from one form of energy to another form of energy) to transmit and receive ultrasound waves, which are reflected when they reach the edge of two structures with different densities. The image produced by an echocardiogram shows the edges of heart structures, but it cannot measure the speed of blood flowing through the heart. Doppler techniques must be integrated to provide this additional information. In a Doppler echocardiogram, sound waves of a certain frequency are transmitted into the heart.

    This is the hardest factor of the principal to test and monitor. It consists of monitoring the individual's heart rate. The harder a person exercises the higher the heart rate and the same with a low intensity exercise, the lower the heart rate. This determines how hard an exercise is for an individual and whether they should try something harder or easier. For example, long distance runners measure their heart rate to see how hard it is for them to run a certain distance.
