The heart is the “engine” of the human body, providing the “power of life”. As the average life expectancy increases, various diseases may affect the normal beating of the heart, and more and more patients need the help of pacemakers to provide additional power. Pacemakers ensure the “power supply” of the human body by storing electrical energy and continuously delivering electrical impulses to stimulate the heart to beat according to a rhythm controlled by a microcomputer chip. Pacemaker development history and trajectory: 1, smaller: currently less than half the size of the palm of your hand 2, lighter: currently only 20-40 grams 3, more functional: from non-physiological pacing to physiological pacing to frequency-adaptive pacing to intelligent pacing, and can be stored to monitor the cardiac rhythm, providing diagnostic information for the physician 4, broader use: from the simple treatment of slow arrhythmias to some of the rapid arrhythmias to malignant arrhythmias (buried arrhythmias) to the heart, the pacemaker can be used for a variety of purposes. Malignant arrhythmia (buried cardioverter defibrillator – ICD), from arrhythmia to heart failure, cardiomyopathy, carotid sinus syncope Indications for artificial cardiac pacemakers: 1, a variety of slow arrhythmias: such as sick sinus syndrome, atrioventricular block, etc. 2, preventive treatment of some of the rapid cardiac arrhythmias: such as frequent atrial premature, atrial tachycardia, atrial fibrillation, etc. 3, malignant arrhythmias: such as ventricular tachycardia, ventricular fibrillation; arrhythmic sudden death, etc. implantation. Sudden death, etc. need to be implanted 4, part of the intractable heart failure: three-chamber pacemaker 5, hypertrophic obstructive cardiomyopathy 6, carotid sinus syncope Surgical procedure: 1, for minor surgery, only local anesthesia 2, vascular puncture (usually for the subclavian vein), pacing electrodes implanted in the endocardium through the blood vessels 3, electrodes coupled with the pacemaker and implanted in the skin together with the capsule bag under the skin 4, after debugging the pacemaker work normally fixed electrodes and pacemaker, suture wound back to the hospital room 5, suture and return to the hospital room. 5, according to the physician’s requirements, lying down for 1-3 days after the operation 6, 7-10 days after the operation to remove the stitches, you can be discharged from the hospital on the next day 7, before discharge, your physician should check the work of the pacemaker, and introduce you to the post-discharge precautions Precautions 1, preoperative and postoperative do not need to avoid food, and appropriate enhancement of nutrition is conducive to the healing of wounds 2, preoperative aspirin, Favara, and other medications should be discontinued or ask your physician 3, Preoperative training in bed urination and defecation 4, during the operation with the physician to complete the cough, inhalation and other actions 5, strictly according to the requirements of the physician to limit the activities of the postoperative period of 1-3 days 6, 1-3 days after the operation can get out of bed, after removing the stitches, should be avoided within 1 month of discharge 7, postoperative attention should be paid to the activities of the operated side of the limbs, to avoid the joints adhesion, rigidity 8, should be asked in detail to ask the physician before the discharge of the life and sports in the precautions, which is very important 9, Come to the hospital for examination 1-3 months after discharge, half a year to one year later, or as required by your physician 10. Don’t forget to bring your pacemaker guarantee card with you when you leave the hospital It is very important to know the guarantee period of your pacemaker and contact your physician half a year to one year in advance to follow up according to your physician’s requirements.
