	<description>I started his blog while in the Paramedic Class in order to share my class notes. I’ve since graduated and now hope to post regularly with articles I find interesting as well as call anecdotes and reviews. Comments always welcome.</description>

		<description><![CDATA[<div id="fb-root"></div>I’ve read many opinions over time about which EKG leads we should be monitoring and I’d concluded that my best 3 to monitor are II, aVL &#038; aVF as the 3 that give the best all around picture of what’s going on. I’ve seen many medics that have their lifepak 12 set to monitor II, [...]]]></description>

		<description><![CDATA[GOOD TO KNOW, to say the least! &#160; (RELATIVE) CONTRAINDICATIONS: Cardioversion is unlikely to be successful and may be harmful in dysrhythmias due to enhanced automaticity (i.e. digoxin toxicity) because a homogenous depolarization state already exists Cardioversion is usually not only ineffective but is associated with a higher incidence of post-shock VT/VF.&#160; Medications are usually [...]]]></description>

		<description><![CDATA[I came across this great article focusing on ECG differences seen with pediatric patients. This is quite important to really know as something as simple as a normal PR interval for an adult could signify a AV block in a child. Electrocardiogram (ECG) interpretation usually is taught in courses that focus on adults. For those [...]]]></description>

		<description><![CDATA[In our protocols we have two beta blockers to choose from depending on the patient’s problem. The two are Metoprolol and Labetalol and they are actually quite different in their actions and therefore, their use. Metoprolol is a selective beta 1 blocker which will specifically block the effects of epinephrine and norepinephrine on the heart. [...]]]></description>

		<description><![CDATA[(Hat tip Medic 122) An explanation I found&#8230;. Because the aortic valve is tight/stenosed, it restricts the amount of blood being ejected from the ventricle. With nitro (and most other drugs that effect peripheral resistance) the peripheral vessels will dilate. A normal ventricle would be able to &#8216;relax&#8217; a bit because peripheral resistance is lowered [...]]]></description>
