What are the different types of pacemakers?
different types of pacemakers can be used externally or internally and may have one or more chamber wires. Electronic pacemakers may vary according to the desired type. The type of pacemaker selected generally depends on the condition requiring treatment. Doctors generally program all these devices during the location and after introduction can regularly adjust the pacemaker.
Transcutaneous external cardiac stimulation (TEP) uses an external pacemaker that cardiologists could temporarily use to modify bradycardia, sinus bradycardia or atrioventricular knots. They can also be used to regulate tachycardia. Although, like defibrillators, external pacemakers are generally not used for asystol or the absence of heart rhythm. This type of pacemaker usually contains large pillows containing electrodes.
One pad is located on the chest above the top of the heart and the other is placed on the chest through the area of the inner shoulder blade. Pacemaker cane deliver up to 200 billion streams for up to 40 milliseconds. Doctors could use these types of pacemakers in conscious or unconscious patients, although a conscious patient would probably get an analgesic and possibly a sedative.
Cardiac resynchronization therapy (CRT) requires an internal pacemaker, which generally consists of a pulsation generator of a match box that contains a battery and a microcomputer. Programmable circuits inside the device capture and heart rhythm times. It can also emit electrical pulses to start muscle contraction. Pulse generators may have one, two or three wires, one end attaching to the unit and the other inserted into the heart muscle. Doctors usually install individual chamber pacemakers or pacemakers with only one lead in patients suffering from atrial anomalies or chamber rhythms.
cardiac surgeons can implant dualCardiostimulators of dual chamber or equipment that have two wires, to the right atrium and right chamber. Biventricular pacemakers generally have three wires that are installed in the right atrium, right ventricles and left ventricles. These devices can be implanted in patients suffering from advanced heart blocks or congestive heart failure.
Standard types of pacemakers supply electrical pulse when the device feels that the heart rhythm has fallen below a certain speed. Some types of pacemakers create impulses on request and adapt the heart rhythm at the time of decrease or increased physical activity. Defibrillator Cardiostimulators also emit electrical impulses when the inner sensor detects a potentially fatal heart rhythm.
