Restrictive cardiomyopathy (RCM) is a rare form of heart muscle disease that is characterized by restrictive filling of the ventricles. In this disease the contractile function (squeeze) of the heart and wall thicknesses are usually normal, but the relaxation or filling phase of the heart is very abnormal.

This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the sigmoid colon is removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining left side of the colon and the top of the rectum. The surgeon may use either sutures or special staples to make this join.

Otitis media with effusion is inflammation and fluid buildup (effusion) in the middle ear without bacterial or viral infection. This may occur because the fluid buildup persists after an ear infection has resolved. It may also occur because of some dysfunction or noninfectious blockage of the eustachian tubes

An antisperm antibody test looks for special proteins (antibodies) that fight against a man's sperm in blood, vaginal fluids, or semen. The test uses a sample of sperm and adds a substance that binds only to affected sperm. Semen can cause an immune system response in either the man's or woman's body. The antibodies can damage or kill sperm. If a high number of sperm antibodies come into contact with a man's sperm, it may be hard for the sperm to fertilize an egg. The couple has a hard time becoming pregnant. This is called immunologic infertility.

Basic ECG Interpretation Our ECG Interpretation Training and Reference Guides provide basic lessons for ECG analysis as well as a quick reference guide for over 40 types of ECG tracings. The arrhythmia drills and quizzes allow you to practice ECG interpretation. What is ECG Interpretation? An electrocardiogram or ECG, records electrical activity in the heart. An ECG machine records these electrical signals across multiple heart beats and produces an ECG strip that is interpreted by a healthcare professional. How Electrocardiograms Work - ECG Strips To briefly summarize the components of a normal ECG tracings, it consist of waveform components which indicate electrical events during one heart beat. These waveforms are labeled P, Q, R, S, T and U. P wave is the first short upward movement of the ECG tracing. It indicates that the atria are contracting, pumping blood into the ventricles. The QRS complex, normally beginning with a downward deflection, Q; a larger upwards deflection, a peak (R); and then a downwards S wave. The QRS complex represents ventricular depolarization and contraction. The PR interval indicates the transit time for the electrical signal to travel from the sinus node to the ventricles. T wave is normally a modest upwards waveform representing ventricular repolarization. ECG Interpretation illustration spacer image ECG Training - Introduction The focus of this introductory ECG course is to provide a tutorial about the main features of ECGs along with a method for analyzing ECGs. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of intervals and segments and the evaluation of other relevant waves. ECG practice exercises serve to reinforce the lesson content.

This short course reviews the main features of EKG tracings. A method for analyzing EKGs is also presented. This method includes assessment of rhythm, calculating heart rate, observing P-wave forms, measurement of EKG intervals and segments and the evaluation of other relevant waves.

Thyroiditis is a general term that refers to “inflammation of the thyroid gland”. Thyroiditis includes a group of individual disorders causing thyroidal inflammation but presenting in different ways. For example, Hashimoto’s thyroiditis is the most common cause of hypothyroidism in the United States. Postpartum thyroiditis, which causes temporary thyrotoxicosis (high thyroid hormone levels in the blood) followed by temporary hypothyroidism, is a common cause of thyroid problems after the delivery of a baby. Subacute thyroiditis is the major cause of pain in the thyroid. Thyroiditis can also be seen in patients taking the drugs interferon and amiodarone.

Transcatheter aortic valve replacement (TAVR) has recently emerged as a therapeutic option for patients with severe aortic stenosis

Nerves are the organs that make up the peripheral nervous system (PNS). They serve as information pipelines that allow the brain and spinal cord to communicate with other tissues and organs. Inside the nerves are the axon processes of sensory and motor neurons (nerve cells).

Cystic acne is a severe type of acne in which the pores in the skin become blocked, leading to infection and inflammation. The skin condition mainly affects the face, but also often affects the upper trunk and upper arms. Acne most often affects adolescents and young adults, with an estimated 80 percent of people between 11 and 30 years of age experiencing acne at some point. Cystic acne is the most severe form and affects far fewer people. In 2009, the Centers for Disease Control and Prevention (CDC) found that acne was the top reason people gave for visiting a dermatologist.

Placenta accreta is the most common accounting for approximately 75% of all cases. Placenta Increta occurs when the placenta attaches even deeper into the uterine wall and does penetrate into the uterine muscle.
