Heart

A heart rhythm disorder is an abnormal variation from the normal heartbeat. Heart rhythm disorders involve abnormalities of one or more of the following: heart rate, regularity of beats, sites where electrical impulses originate, or sequence of activation of heartbeats. Heart rhythm disorder is also referred to as an arrhythmia. The primary function of the heart is to supply blood and nutrients to the body. The regular beating, or contraction, of the heart moves the blood throughout the body.…

Congenital heart disease (CHD) is a defect related to the cardiovascular system. CHD alters the way blood flows into the heart. The irregularity of the heart in people with CHD is developed from birth though symptoms of the condition may not be present until adulthood. During the time of birth the closure of the ductus arteriosus (DA) should occur about 15 hours after birth though functional closure may be delayed for up to 3 months of life. Thus, an open DA is the functional indicator of…

year old male experienced muscle damage in the lower part of the heart because of blocked blood flow. As this happened he fell unconscious because the extra electrical pathways of his heart's chambers stimulated, causing a rapid abnormal heart rate and an insufficient blood supply to the brain. After placing sensors on his body to monitor his heart's electrical activity the healthcare provider established that the front of his heart experienced a blockage in the past. Both events were painless,…

Lab Objective: The purpose of part one of this experiment is to illustrate the relationship between the electrical activity of the heart and the sounds the heart creates. This experiment also analyzes a subject’s physical fitness by measuring the amount of time a subject requires to return to resting level heart rate. Hypothesis: When recording the electrocardiogram for each subject, we expect to see normal sinus rhythm between P wave, QRS waves, and T waves. P waves should be succeeded by…

Cardiovascular Disease: Heart Attack There are many diseases in the medical world which we cannot begin to understand, but there are also many diseases we do understand. These diseases include many cardiovascular diseases and one of them is a heart attack. The dangers and results of this horrific disease affect the lives of people all around the globe but primarily here at home in America. I am going to discuss the effects this disease has on many Americans each and every day. A myocardial…

Introduction The human heart contains various parts. All the parts work together to perform different functions. Some of the functions include contraction, relaxation, receiving, distributing, opening and closing of valves. It is important for the various parts to work together for us to be able to breathe and perform our daily activities. Imagine when one part has a malfunction, how it could affect the others and the human body as a whole. In addition, science and medicine has worked so hard…

Introduction. Ischemic heart disease remains a leading cause of morbidity and mortality worldwide 1. Intermediate coronary artery lesions are responsible for about 80% of acute coronary syndromes2. Accurate assessment of the severity of intermediate coronary stenosis represents an everyday challenge for interventional cardiologists. Fractional flow reserve (FFR), which is simply derived by the ratio between distal (Pd) and proximal (Pa) pressures under conditions of maximal hyperemia, represents…

Heart and Lung Sounds Assessments The knowledge of the normal heart sound, S1 then S2, will aid in the identification of the abnormal heart sounds as the changes of loudness of S1 or the “lub” in “lub-dup” may signify heart pathology. “The second heart sound has been called the key to heart disease” (Shindler, 2007). It is widely transmitted, usually audible, sharper and shorter than S1, and easily heard. Ventricular gallop or S3 is normal in children but not in older populations as it may be…

Since heart disease is the leading cause of death in the U.S, every possible treatment should be done to prevent or to treat the problem. However, preventing heart disease should be prioritize rather than waiting until the last minute. I believe we can prevent most cardiovascular diseases by avoiding the risk factors that we can change in our life. I am going to develop a lifestyle intervention for an individual who has a hypertension and high cholesterol level. Lifestyle change from the…

INTRODUCTION Ischaemic heart disease is the most cause of death in all over the world. When Andreas Gruentzig performed PTCA in human, we have also opened the interventional era which significantly decrease the death cause by Cardial Vascular Disease, especially in Acute Myocardial Infartion. Over 30 years, the ratio of patient admitted to the hospital for myocardial Infarction dramatically decrease from 46,086 to 18,691 per year in 2008 . With the same trend, the proportion ST – segment…
