2. Pacemaker syndrome - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_syndrome

   [1] [3] In general, the symptoms of the syndrome are a combination of decreased cardiac output, loss of atrial contribution to ventricular filling, loss of total peripheral resistance response, and nonphysiologic pressure waves. [2] [4] [5] Individuals with a low heart rate prior to pacemaker implantation are more at risk of developing ...

3. Cardiac contractility modulation - Wikipedia

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

   These side effects are similar to those that occur with other electrical stimulation therapies, such as pacemakers, CRT devices or ICD devices. [30] Furthermore, recorded complications did not differ between patients with activated or deactivated cardiac contractility modulation devices. [17]

4. Artificial cardiac pacemaker - Wikipedia

   en.wikipedia.org/wiki/Artificial_cardiac_pacemaker

   Dual-chamber pacemaker. Here, wires are placed in two chambers of the heart. One lead paces the atrium and one paces the ventricle. This type more closely resembles the natural pacing of the heart by assisting the heart in coordinating the function between the atria and ventricles. [10] Biventricular pacemaker. This pacemaker has three wires ...

5. Pacemaker failure - Wikipedia

   en.wikipedia.org/wiki/Pacemaker_failure

   Pacemaker failure is the inability of an implanted artificial pacemaker to perform its intended function of regulating the beating of the heart. A pacemaker uses electrical impulses delivered by electrodes in order to contract the heart muscles. [ 1 ]

6. Arrhythmia - Wikipedia

   en.wikipedia.org/wiki/Arrhythmia

   This latter group may have more significant side effects, especially if taken for a long period of time. [6] Pacemakers are often used for slow heart rates. [6] Those with an irregular heartbeat are often treated with blood thinners to reduce the risk of complications. [6]

7. Baroreflex activation therapy - Wikipedia

   en.wikipedia.org/wiki/Baroreflex_activation_therapy

   Baroreflex activation therapy is an approach to treating high blood pressure and the symptoms of heart failure. It uses an implanted device to electrically stimulate baroreceptors in the carotid sinus region. This elicits a reflex response through the sympathetic and vagal nervous systems that reduces blood pressure.

9. Heart block - Wikipedia

   en.wikipedia.org/wiki/Heart_block

   Despite the severe-sounding name, heart block may cause no symptoms at all in some cases, or occasional missed heartbeats in other cases (which can cause light-headedness, syncope (fainting), and palpitations), or may require the implantation of an artificial pacemaker, depending upon exactly where in the heart conduction is being impaired and ...
