2. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   CRT is indicated in patients with a low ejection fraction (typically <35%) indicating heart failure, where electrical activity has been compromised, with prolonged QRS duration to >120 ms. [ 2 ] The insertion of electrodes into the ventricles is done under local anesthetic , with access to the ventricles most commonly via the subclavian vein ...

3. Heart failure with reduced ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with_reduced...

   This is defined as a left ventricular ejection fraction (LVEF) of 40% or less. About half of heart failure patients have a reduced ejection fraction. [2] Other types of heart failure are heart failure with mildly reduced ejection fraction (LVEF between 40% and 50%) and heart failure with preserved ejection fraction (LVEF 50% or higher). [1] [3]

4. Heart failure - Wikipedia

   en.wikipedia.org/wiki/Heart_failure

   Heart failure with mildly reduced ejection fraction (HFmrEF), previously called "heart failure with mid-range ejection fraction", [63] is defined by an ejection fraction of 41–49%. [ 63 ] Heart failure with preserved ejection fraction (HFpEF): Synonyms no longer recommended include "diastolic heart failure" and "heart failure with normal ...

   Ejection fraction is the amount of blood that the left ventricle of your heart pumps out each time it contracts. ... Treatment options for coronary artery disease include: Changes to your ...

6. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   An ejection fraction (EF) is the volumetric fraction (or portion of the total) of fluid (usually blood) ejected from a chamber (usually the heart) with each contraction (or heartbeat). It can refer to the cardiac atrium , [ 1 ] ventricle , [ 2 ] gall bladder, [ 3 ] or leg veins, [ 4 ] although if unspecified it usually refers to the left ...

7. Cardiotonic agent - Wikipedia

   According to the European Society of Cardiology (ESC), among cardiotonic agents, Digoxin is specifically recommended as a second-line option for patients with an abnormal left ventricular ejection fraction (≤40%). [85]
