Suggestion: Severe bradycardia.
Cardiac arrest for more than 3 seconds or heart rate often less than 40 times, especially patients with blackheads and sudden fainting, should be implanted with pacemakers. This is also the most important and initial treatment category of pacemakers.
Cardiac systolic weakness
If the disease destroys the myocardium or changes its original shape, it will lead to the inability of the myocardium to contract strongly. Decreased systolic function of the heart will lead to insufficient pumping of blood by the heart, and all parts of the body will not get enough fresh blood, resulting in dizziness, chest tightness and fatigue. For example, congestive heart failure and severe hypertrophic obstructive cardiomyopathy, which are ineffective in drug treatment, can install multiple pacemakers in various parts of the heart and generate multiple electrical stimulation instructions at the same time to help myocardial contraction.
cardiac arrest
Cardiac arrest can kill you in a few minutes. Some diseases can cause cardiac arrest or fatal malignant ventricular arrhythmia (such as tachycardia and ventricular fibrillation). Pacemakers with defibrillation function can be installed to restore the normal beating of the heart.
