Jun 2nd, 2020 - Overview Formation of Amyloid Fibrils. What is amyloidosis? Amyloidosis (am-uh-loy-doh-sis) is a protein disorder. In this disease, proteins change shape (misfold), then bind together and form amyloid fibrils which deposit in organs. As amyloid fibrils build up, the tissues and organs may not work as well as they should. Our bodies make several proteins that can cause amyloidosis. To choose the...

Aug 14th, 2019 - Overview Wolff-Parkinson-White Syndrome - Patrick Tchou, MD What is Wolff-Parkinson-White Syndrome (WPW)? Normally, the heartbeat begins at the sinoatrial (SA) node, located in your right atrium. When the SA node fires, electrical activity spreads through the right and left atria, causing them to contract. The impulses travel to the atrioventricular (AV) node, which is the bridge that allows th...

Jul 19th, 2019 - Overview What is short Q-T syndrome (SQTS)? Short Q-T syndrome is a rare genetic type of abnormal heart rhythm that was discovered in 1999. The electrical activity of the heart is produced by the flow of ions (electrically charged particles of sodium, calcium, potassium, and chloride) in and out of the cells of the heart. Tiny ion channels control this flow. The Q-T interval is the section on t...

https://my.clevelandclinic.org/health/diseases/16765-atrial-fibrillation-afib

Jul 18th, 2019 - Overview The Normal Heart Rhythm The heart pumps blood to the rest of the body. During each heart beat, the two upper chambers of the heart (atria) contract, followed by the two lower chambers (ventricles). These actions, when timed perfectly, allow for an efficient pump. The timing of the heart’s contractions is directed by the heart’s electrical system. The electrical impulse begins in the si...
