through to the right ventricle and then the blood passes through the tricuspid valve entering the lungs and then through to the left atrium and to the left ventricle via the mitral valve and finally into the body. During fetal development, however there are the risks for congenital anomalies. These congenital heart disorders consist of Atrial septal defect (ASD) and Ventricular septal defect (VSD). ASD is one of the common congenital heart defects that requires interventional measures or repair. The

xylazine (10 mg/kg, i.p.). A total of 10 rats were submitted to aortic stenosis surgery, which involved placing a 0.6-mm-i.d. stainless steel clip on the ascending aorta via a thoracic incision (29). A total of 5 age-matched control animals underwent left thoracotomy without clip placement (Sham group). The rats were housed in collective polypropylene cages (2 animals per cage) covered with metallic grids in a

except for the last rhythm strip which occurs at the bottom of the tracing (lead II and V1). The labels of the waves indicate a particular action on the heart. P waves represent atrial depolarization or atrial contraction. The QRS complex indicates ventricular depolarization. While QRS is normally seen not ever complex has Q (negative deflection), R (positive

Research Journal #3 – Left Ventricular Aneurysm Charity Rominger Summary The Tokyo Women’s Medical University shared a new method to repair an aneurysm of the left ventricle of the heart. The technique did not require cutting the ventricle with a ventriculotomy that is necessary with other methods such as plication or circular patch. With this method of repair, the weak wall of an aneurysm was pushed into the ventricle and stitched in place. This type of repair is possible as long as the aneurysm

ventricle caused by a primary disorder of the respiratory system” (Sovari, 2014). Right-sided heart failure usually occurs when pulmonary arterial pressure equals systemic blood pressure; pulmonary hypertension that contributes to the enlargement (hypertrophy, dilation, or both) of the right ventricle (McCance, 2010). It is estimated that in the US alone, cor pulmonale accounts for 6-7% of all types of adult heart disease in addition to 10-30% of decompensated heart failure–related admissions. The

Ergogenic aids are believed to be the miracle working products that help athletes or any physically active person, to enhance their performance (Powers, p. 569). An example of an ergogenic aid is anabolic-androgenic steroids, which are known to build and strengthen the muscle. Athletes who chose to take anabolic-androgenic steroids can choose to either take it orally or inject it within their muscle, to try to enhance their performance within their respective sport. The type of performance that the

2. What are causes of this abnormality? LBBB may be the result as normal variation with age and/or fibrotic conduction system, chronic ischemic heart disease, left ventricular hypertrophy (most commonly from long-standing hypertension), adverse ventricular remodeling from congestive heart failure, or valvular heart disease (ASD). It is not possible to determine the chronicity of the LBBB without reviewing previous ECG tracings. LBBB in AMI may be transient or permanent. Chronic LBBB may have become

Activities such as walking, running, rowing, hiking, cross country Skiing aerobics, dancing step climbing cycling, swimming and known as endurance Sport or aerobic Sport. Endurance sport causes enlargement of the left chamber and thickness of the walls of the heart. This is known as eccentric hypertrophy. Enlargement of the chamber allows more blood into the heart. Anaerobic exercise such as

pumping cambers (ventricles) of the heart. The massive hole in the abnormality itself is a VSD. A VSD is known as a Ventricular Septal Defect. Due to the location of the VSD, two more abnormalities develop. One being that there is a vast blood vessel which take the blood to the body (aorta) is pulled toward, and “overrides” the ventricular septum so that it sits over both the left and right ventricles; this is called an overriding aorta (UMMC, 2013). The second abnormality that takes place is that

cardiomyopathy, and increased cardiac workload, to name a few. Inflammatory, immune, and neurohumoral changes can mediate ventricular remodeling, which will alter myocardial cellular structure resulting in myocardial dilation and further dysfunction of myocyte contractility over time. The decreased contractility will result decreased stroke volume and increased left ventricular end-diastolic volume, which results in dilation of the heart and increased preload. Increased afterload can be caused by
