What symptoms can artificial hearts treat?

With the development of modern medical technology, more and more advanced medical technologies have brought great protection to people's physical health. For example, heart disease is no longer a 100% fatal disease, because people have developed an artificial heart, which is an extremely advanced heart replacement organ with good usability. Let’s take a look at what symptoms artificial hearts can be used for.

(1) Heart block: ① Patients with high-degree or complete and second-degree type II atrioventricular block and recurrent Adams-Stokes syndrome. ② Patients with persistent or intermittent three-branch intraventricular block or symptomatic two-branch intraventricular block.

(2) Sick Sinus Syndrome: ① Patients with severe sinus bradycardia, sinoatrial block, sinus arrest, etc. accompanied by recurrent Adams-Stokes syndrome attacks, or those accompanied by angina pectoris, hypotension, and heart failure. ② Patients with double node disease or bradycardia or tachycardia syndrome who are difficult to treat with medication.

(3) Bradycardia with frequent premature beats.

(4) Children with congenital complete atrioventricular block: ① Those with slow ventricular rate and Adams-Stokes syndrome. ② Patients with slow ventricular rate and heart failure that is difficult to control. ③ The ventricular rate at rest is less than 40 beats/minute, even if there are no symptoms.

(5) Programmable pacemaker for the treatment of refractory tachyarrhythmias.

(6) Triple-chamber pacemaker for the treatment of congestive heart failure due to dilated cardiomyopathy.

Single-chamber pacemakers can generally be installed in the following situations:

① The heart beats too slowly because of a problem with the sinoatrial node, but atrioventricular conduction is good. At this time, an atrial single-chamber pacemaker can be implanted.

② Atrial fibrillation combined with atrioventricular block causes a slow heartbeat, and a single-chamber ventricular pacemaker can be implanted at this time.

③ Pacemakers are only used to prevent occasional but very serious slow heartbeats. At this time, a single-chamber pacemaker can be implanted in the atrium or ventricle, or a dual-chamber pacemaker can be implanted.

A dual-chamber pacemaker has two electrode leads, which are usually implanted in appropriate locations in the right atrium and right ventricle respectively. Generally speaking, the effects produced by a dual-chamber pacemaker are more in line with human needs and are particularly suitable for patients with atrioventricular block. For patients who already have heart failure, it is recommended to install a dual-chamber pacemaker as a first choice. To bottleneck.
