Types of Control Units for Artificial Hearts - Using Stimulator Pacemakers

Page content

The basic functions of the stimulator pacemaker are to monitor the heart’s electrical rhythm. When the pacemaker cannot locate a natural heartbeat, it stimulates ventricles in the heart by using short low voltage pulse. Artificial hearts are designed to operate just like a human heart and technology has greatly increased the functions of the artificial heart valves to act like a biological heart.

Artificial heart valves are designed to last as long as the patient have been typically stress tested to be able to last hundreds of years. The artificial heart valve recipients have to be on anti coagulant drugs after surgery but typically the valves are long lasting and successful.

A pacemaker is a medical device that is used to contract the heart muscles by using electrical impulses. It delivers electrodes to contract the heart muscles and to regulate the beating of the heart. The basic purpose of a stimulator pacemaker is to maintain a regular heart rate. Most pacemakers are able to be programmable and can be set to creating the optimum pacing modes.

There are different methods of pacing that are used in pacemakers. One such pacing method is the percussive method. This is the use of a fist which is located near the sternum’s lowermost edge and is over the right ventricle. It has a striking distance of 20 to 30 centimeters and can induce a ventricular beat. This method is only temporary until the electrical pacemaker can be available to the patient.

Some control units for artificial hearts include a pacemaker and an implantable defibrillator and others use multiple electrodes to stimulate different positions within the heart to improve the synchronization of the lower heart.

Pacemakers are inserted into patients and the patient has an incision in the left shoulder area. A drain is implanted temporarily and is usually removed the day after the surgery. The patient must continue post-operative care after the implant of the stimulator pacemaker and is also required to make necessary lifestyle changes to sustain the heart and health of the body. Most patients feel that they need to modify certain activities that they used to do after receiving a pacemaker and certain activities that include being around magnetic fields should be avoided.

A biventricular pacemaker is a type of pacemaker that can pace both the ventricles. By being able to pace both sides of the heart the pacemaker is able to resynchronize a heart that is not beating in a synchronizing pattern. These devices have three leads – one in the atrium, one in the right ventricle and one are inserted through the coronary sinus. Different forms of pacemakers and control units for artificial hearts include the ability to be able to see the atrial and ventricular chambers in the heart. Another method of pacing is the external pacing method. This is used for the initial stabilization of bradycardias. The procedure is done by placing two different pacing pads on the chest. The person selects of the rate of the pacing and gradually increases it.
