<ul>
    <li>Pacing systems</li>
    <li>Implantable cardiac defibrillators (ICDs)</li>
    <li>Automatic external defibrillators (AEDs)</li>
</ul>
<h3>Pacing Systems</h3>
<p>Pacing systems consist of pacemakers and programmers that are needed to monitor and correct slow heart rhythms.&nbsp;The following&nbsp;pacing system&nbsp;components work together to relieve symptoms of bradycardia (slow heart rate):</p>
<ul>
    <li>Pacemaker&mdash;Implantable device that electrically stimulates the heart to pump blood.&nbsp;It contains an electronic circuit and a battery.</li>
    <li>Pacing Lead&mdash;An insulated wire that carries a tiny electrical pulse to the heart to initiate&nbsp;heartbeat.&nbsp;</li>
    <li>Programmer&mdash;Monitors the pacemaker.&nbsp;Cyclone&trade;&nbsp;II FPGAs and MAX<sup><font size="2">&reg;</font></sup>&nbsp;II CPLDs are ideal candidates for&nbsp;use in programmers (see below for more information).</li>
</ul>
<h3>Implantable Cardiac Defibrillators</h3>
<p>ICDs&nbsp;are similar to pacing systems in that they continuously monitor the heart&rsquo;s rhythm. Specifically, ICDs treat tachyarrhythmia (fast heart beat).&nbsp;If the heart beats too quickly,&nbsp;the ICD issues a lifesaving jolt of electricity to restore the heart&rsquo;s normal rhythm and prevent sudden cardiac death. Like pacing systems, ICDs have similar components, including a defibrillator, lead, and a programmer that is&nbsp;ideally suited for low-power Cyclone II&nbsp;and MAX II devices.</p>
<h3>Automatic External Defibrillators</h3>
<p>AEDs are used to jump-start a heart that&nbsp;has failed due to heart attack or&nbsp;cardiac arrest.&nbsp;Designed&nbsp;so that even a&nbsp;layman can operate it without much difficulty,&nbsp;AEDs are rapidly gaining popularity.&nbsp;They can even be found in public places such as airports, train stations, and airplanes. Due to their low cost and high performance, Cyclone II FPGAs and&nbsp;MAX II CPLDs are perfect for use in AEDs.</p>
<h3>Low-Cost Programmable Solutions for CRM Applications</h3>
<p>Altera&rsquo;s low-cost&nbsp;, low power <a href="/products/devices/cyclone2/cy2-index.jsp">Cyclone II FPGAs</a>&nbsp;and <a href="/products/devices/cpld/max2/mx2-index.jsp">MAX&nbsp;II CPLDs</a> are ideal for CRM applications because they provide the most cost-effective programmable solution for data processing. Cyclone&nbsp;II&nbsp;FPGAs and MAX&nbsp;II CPLDs also contain system functions that complement available ASSPs, such as on-screen display (OSD) and timing display.</p>
<p>Altera&rsquo;s Cyclone series of FPGAs offer designers unparalleled capability at the lowest cost. Designed on an advanced, highly efficient architecture, Cyclone&nbsp;II FPGAs feature high density and performance that easily meet&nbsp;the price requirements of high-volume CRM applications. For a high-performance, cost-efficient processing solution, Altera&rsquo;s Nios<sup><font size="2">&reg;</font></sup>&nbsp;II embedded processors can be implemented in a Cyclone II device.</p>
<p>Altera&rsquo;s MAX series of CPLDs include the industry&rsquo;s most successful and widely used CPLD solutions. Altera&rsquo;s latest CPLDs, MAX II devices, are designed for low-cost and low-power applications. MAX 3000A devices are optimized for high-volume, cost-sensitive applications. The non-volatile and low-cost features of the MAX&nbsp;series make them ideal for functions such as address decoding, system timing, and system bug fixes.</p>
