While a colleague obtains peripheral I.V. access‚ you attach a cardiac monitor‚ which shows sinus tachycardia with frequent premature ventricular contractions (PVCs). Next‚ you use the SAMPLE mnemonic to conduct a secondary survey: Signs and symptoms: palpitations‚ shortness of breath with exertion; lightheadedness when changing from a supine to a sitting position; no chest pain‚ nausea

Most of the cardiac injury ultimately results in development of cardiac fibrosis due to negligible regenerative capacity of heart. Cardiac fibrosis is associated with increased deposition of matrix proteins in the myocardium. The expansion of the cardiac interstitial space in absence of significant cardiomyocyte loss is “reactive interstitial fibrosis” and the formation of scar in response to myocardial infarction is called “reparative fibrosis” [10‚ 46]. Increased deposition of endomysial and perimysial

Etiology & Risk Factors Congestive Heart Failure can be brought on by many conditions. These conditions include Coronary Artery Disease‚ Heart Attack‚ and lastly Cardiomyopathy. Coronary artery disease can develop in humans after years over time after years of fatty deposits in the vascular system (Arteriosclerosis). After a heart attack the heart muscles are weakened and cannot perform the way they could prior to the attack. Therefore‚ as the muscles lose their pumping ability the heart cannot work

Cardiopulmonary Resuscitation (CPR) is a lifesaving technique useful in many emergencies‚ including heart attacks‚ near downing‚ when absence of breathing‚ or absence of a heart beat. In our fast paced world‚ there is a growing need for quick reaction in an emergency situation. Anyone can learn CPR. Did you know that 88% of cardiac arrest occurs at home? Knowing how to perform CPR can triple he victim’s chances of survival. If you are fearful your knowledge or abilities are not 100%‚remember

Heart Diseases Arrhythmogenic right ventricular dysplasia Arrhythmogenic right ventricular dysplasia is a genetic disease in which normal heart tissue is progressively replaced with fat and scar tissue. According to St. Lukes-Roosevelt Hospital Center‚ tissue damage occurs predominantly in the right chamber of the heart. People who inherit this genetic disease may develop arrhythmias‚ or abnormal heart rhythms. Arrhythmogenic right ventricular dysplasia is a known cause of sudden death from

Which Word?: Exercises 5.31–5.35. Select the correct answer‚ and write it on the line provided. High-density lipoprotein-cholesterol is also known as good cholesterol. An abnormally slow resting heart rate is described as bradycardia. In atrial fibrillation‚ instead of pumping strongly‚ the heart muscle quivers ineffectively. The highest pressure against the blood vessels is systolic pressure‚

through the heart disrupts the normal coordination of heart muscles. These muscles lose their vital rhythm and begin a process known as ventricular fibrillation. Death soon follows. 0.25 Amps/250mA is equal to the current flowing through a 60W Bulb. What is ventricular fibrillation? The heart beats when electrical signals move through it. Ventricular fibrillation is a condition in which the heart’s electrical activity becomes disordered. When this happens‚ the heart’s lower (pumping) chambers
