<p><b>Cardiac monitoring</b> generally refers to continuous or intermittent <a href="Monitoring_(medicine)" title="Monitoring (medicine)">monitoring</a> of <a href="Heart" title="Heart">heart</a> activity to assess a patient's condition relative to their <a href="Cardiac_cycle" title="Cardiac cycle">cardiac rhythm</a>.

The two may be performed simultaneously on <a href="Critical_care_medicine" class="mw-redirect" title="Critical care medicine">critical</a> heart patients. Cardiac monitoring for ambulatory patients (those well enough to walk around) is known as ambulatory electrocardiography and uses a small, wearable device, such as a <a href="Holter_monitor" title="Holter monitor">Holter monitor</a>, <a href="Wireless_ambulatory_ECG" title="Wireless ambulatory ECG">wireless ambulatory ECG</a>, or an <a href="Implantable_loop_recorder" title="Implantable loop recorder">implantable loop recorder</a>.

</p>
<ul><li>Class I: Cardiac monitoring is indicated in all or most patients.</li>
<li>Class II: Cardiac monitoring may be beneficial, but it is not essential.</li>
<li>Class III: Cardiac monitoring is not indicated because the patient's serious event risk is low. Monitoring will not have therapeutic benefit.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup></li></ul>

<p>In the setting of out-of-hospital <a href="Acute_(medicine)" title="Acute (medicine)">acute medical care</a>, ambulance services and other <a href="Emergency_medical_services" title="Emergency medical services">emergency medical services</a> providers utilize heart monitors to assess the patient's cardiac rhythm.

<p>Some digital patient monitors, especially those used by EMS services, often incorporate a defibrillator into the patient monitor itself. These monitor/defibrillators usually have the normal capabilities of an ICU monitor, but have manual (and usually semi-automatic AED) defibrillation capabilities. This is particularly good for EMS services, who need a compact, easy to use monitor and defibrillator, as well as for patient transport. Most monitor defibrillators also have transcutaneous pacing capability via large AED like adhesive pads (which often can be used for monitoring, defibrillation and pacing) that are applied to the patient in an anterior-posterior configuration. The monitor defibrillator units often have specialized monitoring parameters such as waveform capnography, invasive BP, and, in some monitors, Masimo Rainbow SET pulse oximetry, which can also monitor <a href="Carbon_monoxide" title="Carbon monoxide">carbon monoxide</a> and <a href="Methemoglobin" title="Methemoglobin">methemoglobin</a> levels. Most modern monitors also allow for transmission of an ECG sample to an emergency department for interpretation; this process may be used to speed up patient care in certain situations, such as bypassing the ED and proceeding to a <a href="Cath_lab" class="mw-redirect" title="Cath lab">cath lab</a>.

<p>There are two broad classifications for cardiac event monitors: manual (or dumb) and automatic. Automatic ECG event monitors have the ability to monitor the patient's ECG and make recordings of abnormal events without requiring patient intervention. Manual ECG event recorders require the patient to be symptomatic and to activate the device to record an event; this makes these devices useless whilst, for example, the patient is sleeping. A third classification, the <a href="Implantable_loop_recorder" title="Implantable loop recorder">implantable loop recorder</a>, provides both automatic and manual abilities.
</p><p>An example of automatic monitoring is the transtelephonic cardiac event monitor. This monitor contacts ECG technicians, via telephone, on a regular basis, transmitting <a href="ECG" class="mw-redirect" title="ECG">ECG</a> rhythms for ongoing monitoring. The transtelephonic cardiac event monitor can normally store approximately five "cardiac events" usually lasting 30–60 seconds.

Such heart rate monitors are largely used by performers of various types of <a href="Physical_exercise" class="mw-redirect" title="Physical exercise">physical exercise</a>.
</p><p>A generic cardiac monitor has the following functions:
</p>
<ul><li>A display of heart rate and heart rhythm</li>
<li>Sound alarms above and below a pre-set limit</li>
<li>Ability to determine the presence of arrhythmia</li></ul>
<p>There are many different types of cardiac monitors. In personal use, the <a href="Holter_monitor" title="Holter monitor">Holter monitor</a> is an external monitor which uses wires with patches that attach to the skin to continuously measure and record heart activity for 1–2 days.<sup id="cite_ref-5" class="reference"><a href="#cite_note-5"><span class="cite-bracket">[</span>5<span class="cite-bracket">]</span></a></sup> An Event Recorder can be worn on the body for up to 30 days.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup> A Mobile Cardiac Telemetry unit is a wearable monitor that detects, records, and transmits heart rhythms for up to 30 days.
