What is Permanent Pacemaker?
(Foreword: Permanent Pacemaker article is written only to ease up internet search for “Permanent Pacemaker” and to help resolve this issue. To clarify in further text biventricular pacemaker is also a type of permanent pacemaker and do not let this confuse you.)
A permanent pacemaker consists of a generator and leads which are implanted into the upper chest through a small incision. The generator is a metal case containing the power source and a timer that regulates how often the pacemaker sends out electrical signals. As mentioned in cardiac pacemaker article here you will be able to find out everything you need about permanent pacemaker. The first permanent pacemaker was implanted in 1958. A Biventricular pacing is a device that is used to coordinate the chambers of the heart so that they pump more effectively. Risks are the same like for any pacemaker implantation surgery. It could be notable to say that there are three main types of permanent pacemakers, depending on the number of chambers involved: single-chamber pacemaker, dual-chamber pacemaker, rate-responsive pacemaker. Since I have said almost everything one needs to know about pacemaker in previous articles, keeping my main focus on biventricular pacemaker
I will use my space here to write a tell you a short story that happened in my hospital: 
A few years ago a very old patient came in a very bad condition. Apparently the patient had a heart stroke and the family brought his Pacemaker ID. They were not aware how can a patients have heart problem after they got successfully implanted their permanent pacemaker, so they complained there was a pacemaker failure. The truth was something different: Pacemaker was still working, but the heart stopped working. Heart is a complex organ and in this specific case it just got tired, because of the age and condition of a patient. Permanent pacemaker will help you pump blood into organs, it will keep your heart working, extend your life and probably be your lifesaver for some years, but the truth is no one, not even a most skillful surgeon or cardiologist can predict how much will it take for your heart to get tired of its life. A specific risk are people over 60 years, but thanks to this remarkable device they can still live their life in normal way. True lifesaver – a permanent pacemaker!
Biventricular pacemaker, also known as CRT (cardiac resynchronization therapy) is a type of pacemaker that can pace both the septal and lateral walls of the left ventricle. As promised in
