stronger and with a more regular rhythm. Digoxin is used to treat heart failure. Digoxin is also used to treat atrial fibrillation‚ a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart). Important information about digoxin You should not use this medication if you are allergic to digoxin‚ or if you have ventricular fibrillation (a heart rhythm disorder of the ventricles‚ or lower chambers of the heart that allow blood to flow out of the heart)

starting from the SA node. SA node → AV node → AV bundle (bundle of His) → → Purkinje fibers left and right bundle branches At what structure in the transmission sequence is the impulse temporarily delayed? AV node Why? Allows completion of atrial contraction before initiation of ventricular systole. 2. Even though cardiac muscle has an inherent ability to beat‚ the nodal system plays a critical role in heart physiology. What is that role? Ensures that depolarization proceeds in an orderly

Congestive Heart Failure Toni Belsito Brookdale Community College HESC 105 Medical Terminology Congestive Heart Failure Congestive heart hailure‚ also known as CHF or heart failure‚ affects the lives of 5 million Americans each year with 550‚000 new cases diagnosed yearly. (Emory healthcare‚ 2013) CHF is a medical condition in which the heart has become weak and cannot pump enough blood to meet the need for oxygen rich blood required by the vital organs of the body‚ less blood is pumped

people with a high risk of stroke and people with atrial fibrillation. More than 2.7 million Americans have atrial fibrillation (AF)‚ an-arrhythmia of the heart where the atria (the heart’s pumping chambers) quiver instead of beat. As a result‚ not all of the blood is pumped out of the heart‚ allowing pools to collect in the heart chamber‚ where clots may form. An embolic stroke is a type of ischemic stroke that occurs when a piece of an atrial blood clot (embolus) is pumped out of the heart‚ circulates

The speedier heart rate kind are supraventricular which is simply quick heart rates‚ atrial fibrillation which this kind is the most widely recognized genuine arrhythmia. It has quick beats and sporadic constriction. Atrial shudder is the same however the constriction is normal rather than sporadic. Paroxysmal supraventricular tachycardia is a quick heart rate‚ where the heart rate can turn out to be quick
