DIATHERMY ‘Diathermy' means 'through heating' or producing deep heating directly in the tissues of the body. Externally applied sources of heat like hot towels, infrared lamps and electric heating pads often produce discomfort and skin burns long before adequate heat has penetrated to the deeper tissues. In diathermy technique, the subject's body becomes a part of the electrical circuit and the heat is produced within the body and not transferred through the skin VM Umale Dept. of Electronics and Telecommunication Engineering 7

Electrotherapy Typical i-t curves of a normal muscle and degenerated muscle. The curve shows that decreasing excitability with progressive degeneration requires extended stimulation times and increased current strength for achieving successful stimulation The chronaxie and rheobase can be easily read from the i-t curves. The rheobase is the minimum intensity of current that will produce a response if the stimulus is of infinite duration, in practice an impulse of 100 ms being adequate for estimating this. The chronaxie is the min. duration of impulse that will produce a response with a current of double the rheobase. For example if the rheobase is 6 m. A, the chronaxie is the duration of the shortest impulse that will produce a muscle contraction with a current of 12 m. A. VM Umale Dept. of Electronics and Telecommunication Engineering 9

Other type of pulse Biphasic Stimulation: : § The cell recovery from the effect of a stimulus current can be hastened by the passage of a lower intensity current of opposing polarity over a longer period so that the net quantity of electricity is zero. § Combination of positive and negative pulses is called biphasic stimulation. § The stimulating pulse may be followed by a pulse of opposite polarity of onetenth the amplitude and 10 times the width. § Biphasic stimulation also helps to neutralize the polarization of the recording electrodes in case silver-silver chloride electrodes are not used. This means that there are no electrolytic effects, nor are any macroscopic changes affecting either the skin or the electrodes observed. § Also, there is reduced muscle fatigue, since each current pulse is immediately followed by an opposite current phase of the same magnitude. § The stimulation current intensity required during treatment is less as compared with monophasic currents.

Stimulators Other stimulators 3. Transcutaneous electrical Nerve stimulator(TENS) Transcutaneous electrical nerve stimulation (TENS) therapy involves the use of low-voltage electric currents to treat pain. Electrodes or mediums for electricity to travel to the body, placed on the body at the site of pain deliver electricity that travels through the nerve fibers. The electric currents block the pain receptors from being sent from the nerves to the brain. A patient will receive a small, battery operated TENS machine to use at home. In most cases, a doctor, physical therapist, or acupuncturist adjusts the machine to the correct settings. The provider shows the patient how to use the machine before sending him or her home with the TENS device. VM Umale Dept. of Electronics and Telecommunication Engineering 24

CARDIAC PACEMAKER : Fixed Rate Pacemaker: This type of pacemaker is intended for patients having permanent heart blocks. The rate is pre-set, say at 70 bpm. The rate can be varied externally in implanted units by magnetically actuating a built-in relay. Since the fixed rate pacemaker functions regardless of the patients' natural heart rhythm, it poses a potential danger because of competition between the patients' rhythm and that of the pacemaker. Demand Pacemaker: These pacemakers have gradually almost replaced the fixed rate pacemakers because they avoid competition between the heart's natural rhythm and the pacemaker rhythm. The demand unit functions only when the R-R intervals of the natural rhythm exceed a pre-set limit. R wave Triggered Pacemaker: The ventricular synchronized demand type (R wave triggered) pacemaker is meant for patients who are generally in heart block with occasional sinus rhythm. The pacemaker detects ventricular activity (R wave of ECG) and stimulates the ventricles after a very short delay time of some milliseconds. If there is sinus rhythm, the stimulating impulse will occur in the ventricular de-polarization. If there is asystole, the unit will stimulate the heart after a pre-set time.

CARDIAC PACEMAKER : Ventricular Inhibited or R Wave Blocked Pacemaker: The ventricular inhibited type (R wave blocked) pacemaker is meant for patients who generally have sinus rhythm with occasional heart block. The circuitry detects spontaneous R wave potentials at the electrodes and the pacemaker provides a stimulus to the heart after pre-set asystole. However, in the case of ventricular activity, the R-wave does not trigger the output circuit of the pacemaker but blocks the output circuit and no stimulation impulse is given to the heart. Atrial Triggered Pacemaker: This is a R wave triggered or atrial triggered pacemaker. The pacemaker detects the atrial de-polarization and starts the pulse forming circuits after a delay so that the impulse to the ventricles is delivered after a suitable PR interval. The major advantage of this pacemaker is its ability to provide maximum augmentation of cardiac output at changing atrial rates to meet various physiological requirements. Dual Chamber Pacemakers: These devices are capable of treating the majority of those patients who suffer from diseases of the sino-atrial node by providing atrial stimulation whenever needed. In these devices, both the atria and the ventricles are sensed and stimulated as needed while maintaining proper synchronization of the upper and lower chambers. Rate–adaptive features available with dual chamber pacemakers include the automatic adjustment of stimulus intensity and gains for the various sensing channels.
