An EKG records the strength, rhythm, and the timing of electrical signals as they pass through each part of the heart. It should be done within 10 minutes of being admitted to hospital. The ST elevations and Q waves are significant for diagnosing and determining the treatment for a MI.
During the initial assessment of a heart attack, the EKG shows an elevated ST segments. The ST segment elevation myocardial infarction (STEMI) also known as Q-wave MI is the most severe type of the MI. It indicates that an artery to the heart is blocked and that the full thickness of the heart muscle is damaged. The Non-ST segment elevation myocardial infarction (NSTEMI) also known as a non Q-wave MI is considered less severe than the STEMI. A smaller section

Mark’s Hospital, Mr. Gomez spends his morning seated behind a computer monitor and blood glucose testing machines to observe patients exercising on various machines and weights while in a typical rehabilitation program for six to eight weeks with sessions being 50 to 120 minutes long. When patients with diabetes have low blood glucose upon arrival, he hands them a small can of juice to prevent fainting. He uses the program Q-Tel RMS to check the electrocardiograms for any irregular patterns. When anomalies occur, he will stop the patient and check on how she or he is feeling. He may need to refer them to another floor to be seen by another healthcare professional such as a cardiologist to find out what is going on.
Systolic and Diastolic Heart Failure Heart failure occurs when the heart cannot pump enough blood for the body due to a weakened or damaged heart. The heart 's pumping action moves oxygen-rich blood as it travels from the lungs to the left atrium, then on to the left ventricle, which pumps it to the rest of the body. The left ventricle supplies most of the heart 's pumping power, so it 's larger than the other chambers and essential for normal function. (American Heart Association). In left-sided or left ventricular heart failure, the left side of the heart must work harder to pump the same amount of blood.
Supraventricular Tachycardia Narrow complex tachycardias are defined by the presence in the electrocardiogram of a QRS complex with less than 120 msec duration and a heart rate more than 100 beats per minute. They are usually of supraventricular origin, though narrow complex ventricular tachycardias were rarely reported in the literature (Hayes et al, 1991). Supraventricular origin of the tachycardia means the obligatory involvement of one or more of the cardiac structures above bifurcation of His bundle. Those include the atrial myocardium, the AV node, the proximal His bundle, the coronary sinus, the pulmonary veins, the venae cavae, or abnormal atrio-ventricular connections, namely bypass tracts (Lau, 2008). Although pharmacologic treatment is still in use for suppression and treatment of SVTs, particularly for atrial arrhythmias, reported efficacy and side effects limited their application.
Cardiogenic shock is caused when your heart cannot pump enough blood to meet your body 's needs. This is typically caused by a severe heart attack, but can also be caused by inflammation and infection in the heart. Cardiogenic shock signs and symptoms include rapid breathing, severe shortness of breath, sudden, rapid heartbeat, loss of consciousness, weak pulse, sweating, pale skin, cold hands or feet, and urinating less than normal or not at all. The risk of Cardiogenic shock increases if a person is; older, has a history of heart failure or heart attack, has blockages in several of the heart 's main arteries, and has diabetes or high blood pressure. Cardiogenic shock is usually diagnosed in a medical setting; therefore the first aid care is the same as general shock.
This type of shock occurs when the heart is unable to pump blood effectively. This is evident to patients who have had myocardial infarction, such as John’s case. In this illness, the heart has decreased contractility resulting to decreased cardiac output. Such decrease will stimulate the sympathetic nervous system to activate the compensatory mechanism by increasing the heart rate as evident in John’s vital sign to increase the peripheral pressure and ventricular
Most systems that automatically gather data with this strategy take a “median” of the vital sign data over a 15 min time interval to smooth the data (Warner et al 1968; Gardner et al. 1991; Vawdrey et al. 2007). This strategy provides real-time data for computations and computerized decision support for the hospital’s EHR and is the preferred strategy. (Gardner, Clemmer, Evans, Mark,
Another common test is cardiac catheterization. By running small tubes, called catheters, through the veins and injecting contrast dye, doctors can determine the blood pressure and blood flow levels inside the heart. A third usual test is an Echocardiogram where doctors take an ultrasound of the heart. It’s basically a movie showing the heart, and almost all defects/problems can be detected by it (Common Tests for Heart Disease). These modern marvels of medicine are key to quick diagnosis and
Results 2.0 The shape of the Ventricular function Curve. A Ventricular function Curve was created by plotting Left Ventricular End-diastolic pressure against stroke work. The curve In Figure 1, displays that increase as increase LVEDP increase SW also increased as expected by starling Law of the heart. The ventricular function curve appears to only display the part of the ascendingly limb when compared to traditional curves as there is no sign of plateauing of high Pressure the sharp line of the ascendingly limb seen during low pressure. Most importantly, relative to baseline, with similar Left ventricular end diastolic pressure, the stroke Work was reduced.
Most often the blood pressure is tested by a healthcare worker using a gauge, sensor, or a stethoscope and they measure the systolic pressure (blood pressure when the heart beats) and the diastolic pressure (blood pressure between heartbeats). The reading is systolic over diastolic, for example, 120/80. The heartbeat
6. Inflammatory Disease of Heart: Myocarditis is in fact an inflaming of the heart muscle. It is frequently present with a severe attack of dyspnea or/and a disorderly heart beating and can develop fast. It is often caused by viral infections. Pericardial disease is a sickness of the sac around the heart.
I enjoyed reading your discussion post and it is very informative. I am glad to hear that everything went well with your past pregnancy and I am happy that you delivered a healthy baby. You brought up a great point about having a serious condition without having any types of symptoms. It is easy to misdiagnose an elderly patient because some of their presenting symptoms are atypical. For example, an elderly patient who is suffering of myocardial infarction might not feel a chest pain.
Electrocardiograms are abnormal in 75-90% of patients with HCM with abnormalities such as ST changes with T wave inversions, and prominent Q waves especially in the inferior and mid-precordial leads. 22, 23 Non-invasive imaging is important for diagnosis, including echocardiogram and MRI.20 Coronary artery anomalies The second most common cause of SCD are coronary abnormalities with ectopic origins from aorta (also known as anomalous origin of a coronary artery (AOCA) from the opposite sinus of Valsalva) and the pulmonary trunk (also known as anomalous origin of a coronary artery (ALCAPA) from the pulmonary artery) most commonly.24 In cases of AOCA that cause SCD, the left or right coronary exits from
