2. Cardiac contractility modulation - Wikipedia

   en.wikipedia.org/wiki/Cardiac_contractility...

   Heart failure is a chronic disease that usually progresses gradually. [20] The rate of progression and the degree of symptoms of the disease varies between different patients. Cardiac contractility modulation therapy aims to treat heart failure through a medium- to long-term treatment, over the course of weeks and months. [citation needed]

3. Tachycardia-induced cardiomyopathy - Wikipedia

   People with TIC most often present with symptoms of congestive heart failure and/or symptoms related to their irregular heart rhythm. [1] Symptoms of congestive heart failure can include shortness of breath, ankle swelling, fatigue, and weight gain. [2] Symptoms of an irregular heart rhythm can include palpitations and chest discomfort. [2]

4. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   Pacemakers that control both the atria and ventricles are called dual-chamber pacemakers. Although these dual-chamber models are usually more expensive, timing the contractions of the atria to precede that of the ventricles improves the pumping efficiency of the heart and can be useful in congestive heart failure.

5. Cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Cardiac_pacemaker

   An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...

   Patients with heart failure are misdiagnosed at a rate of 16% in hospitals and nearly ... They can hear the heart beating and watch the blood and oxygen flow—all without cutting into the patient ...

7. Ventricular assist device - Wikipedia

   en.wikipedia.org/wiki/Ventricular_assist_device

   A ventricular assist device (VAD) is an electromechanical device that provides support for cardiac pump function, which is used either to partially or to completely replace the function of a failing heart. VADs can be used in patients with acute (sudden onset) or chronic (long standing) heart failure, which can occur due to coronary artery ...
