Protocols for antitachycardial pacing including biphasic stimulation administered at, or just above, the diastolic depolarization threshold potential; biphasic or conventional stimulation initiated at, or just above, the diastolic depolarization threshold potential, reduced, upon capture, to below threshold; and biphasic or conventional stimulation administered at a level set just below the diastolic depolarization threshold potential. These protocols result in reliable cardiac capture with a lower stimulation level, thereby causing less damage to the heart, extending battery life, causing less pain to the patient and having greater therapeutic effectiveness. In those protocols using biphasic cardiac pacing, a first and second stimulation phase is administered. The first stimulation phase has a predefined polarity, amplitude and duration. The second stimulation phase also has a predefined polarity, amplitude and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is first applied and followed by cathodal stimulation. In this fashion, pulse conduction through the cardiac muscle is improved together with the increase in contractility.

A semiconductor substrate is manufactured in which a plurality of single crystal semiconductor layers is fixed to a base substrate having low heat resistance such as a glass substrate with a buffer layer interposed therebetween. A plurality of single crystal semiconductor substrates is prepared, each of which includes a buffer layer and a damaged region which is formed by adding hydrogen ions to each semiconductor substrate and contains a large amount of hydrogen. One or more of these single crystal semiconductor substrates is fixed to a base substrate and irradiated with an electromagnetic wave having a frequency of 300 MHz to 300 GHz, thereby being divided along the damaged region. Fixture of single crystal semiconductor substrates and electromagnetic wave irradiation are repeated to manufacture a semiconductor substrate where a required number of single crystal semiconductor substrates are fixed onto the base substrate.

Embodied in the flexile forms of both an endless-loop and as a linear-tape, a unique tooth flossing device for cleaning away bacteria between the teeth is set forth. Comprised of a nontoxic extrusion-molded thermo-plastic polyurethane having particular properties of excellent elasticity, almost film-like guage of thickness, and a natural random surface-texture serving to aid the flossing procedure. In use, a FLOSS-LOOP(TM) is simply held in the user's thumb-&-forefinger of both hands, so as to pre-stretch "thin" that portion to be slid vertically between the teeth. The exceptionally high stretched tensile-strength of this device enables it to endure the duress of insertion between the teeth, yet once interposed interstitially adjacent the gum-line, the release of excess tension upon the tensioned segment of the loop enables it to resume it's natural thickness-guage of approximately 0.325 mm(0.0128-inch). This novel variable-guage capability of the device, making it able to more effectively burnish away substances from the tooth and sulcus of the gum-tissue during it's thicker guage modality; then again be retensioned to approximately only 0.200 mm-guage for easy interstitial removal. Either version of the device may be coated with various agents effective in combating diseases of the teeth and gums.
