Pacemakers are divided into two main categories: temporary and permanent. Permanent pacemakers primarily include VVI, DDD, ICD, and CRT types.
VVI Pacemaker: This is a single-lead, the most basic, and economical type of pacemaker. It is used to meet simple heart rate support needs in specific patient groups.
DDD Pacemaker: This is a dual-lead pacemaker. It offers more comprehensive heart rate management by coordinating both atrial and ventricular contractions and is preferred in a wide range of patients.
Implantable Cardioverter-Defibrillator (ICD): Also known as a defibrillator, an ICD has the ability to deliver electroshocks. Its primary purpose is to prevent sudden cardiac death by detecting life-threatening ventricular arrhythmias. This device, which can also be beneficial in some patients with advanced heart failure, is generally larger than standard pacemakers.
Cardiac Resynchronization Therapy (CRT): Used in patients with heart failure, CRT devices improve ventricular synchronization and increase the heart's pumping power by correcting electrical conduction delays within the heart. CRT devices can also include an ICD feature (referred to as CRT-D), thus playing a life-saving role in suitable patients by providing both resynchronization and arrhythmia protection.
