first-to-market MultiPoint Pacing technology. The MultiPoint Pacing technology has been shown to enhance patients’ response to CRT (Cardiac Resynchronization Therapy) (CITE). The technology allows physicians the opportunity to capture more left ventricular tissue quickly by delivering pacing pulses to multiple left ventricle locations rather than the traditional single pulse for each heartbeat (CITE). MultiPoint technology offers physicians more options to manage heart failure and facilitates additional

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

In 1899‚ J A McWilliam reported in the British Medical Journal of his experiments in which application of an electrical impulse to the human heart in asystolecaused a ventricular contraction and that a heart rhythm of 60-70 beats per minute could be evoked by impulses applied at spacings equal to 60-70/minute.[1] In 1926‚ Dr Mark C Lidwell of the Royal Prince Alfred Hospital of Sydney‚ supported by physicist Edgar H Booth

threatening. A person with congestive heart failure feels tired because not enough blood circulates to supply the body’s tissues with the oxygen and nutrients they need. Abnormalities of the heart structure and rhythm also can be responsible for left ventricular congestive heart failure. In right-sided heart failure‚ the lower right chamber of the heart (right ventricle) cannot pump blood to the lungs as fast as it returns from the body through the veins. Blood then

delivery of a shock from the AED should be no longer than five minutes for the best outcomes (American Heart‚ 2010). This has to do with an This is due to the fact that about half of witnessed cardiac arrests are the shockable rhythm of ventricular fibrillation for the first few minutes of arrest. With each hallway having access to an AED‚ help will be provided to shock within the recommended time frame and increase the number of children who survive a cardiac arrest (American Heart‚ 2010).

Therapeutic hypothermia is used to potentially decrease or prevent any kind of neurologic deficit that could occur post - arrest from decreased perfusion and oxygenation to the brain. The benefits of starting this are exponential and “…decreases free radical production‚ inflammatory pathways‚ cellular

after all it is not as hard as it seems. Everything one doesn’t understand is taught in one class called EKG. One of the most important things to learn is the arrhythmias which are greatly different. The sinus‚ atrial‚ junctional‚ heart‚ and ventricular rhythms are all important part to learn and understand to fully complete such course. The first categories of arrhythmias which originate in the sinus node are called Normal Sinus Rhythm (NSR)‚ Sinus Bradycardia‚ Sinus Tachycardia‚ and Sinus
