		<title>Atrial Flutter with High-Degree AV Block and Ventricular Standstill</title>
		<description><![CDATA[


Sorry for not posting much lately, folks! I guess I&#8217;ve just been too busy&#8230;! Anyway, hope you like this one. It was brought to me by a colleague who thought I might enjoy it. He was perfectly right about that! 
The patient: Elderly male, admitted to the CCU for near syncopes and episodic dizziness. He [...]]]></description>

		<title>Site update!</title>
		<description><![CDATA[Dear friends!
As you&#8217;ve probably discovered already, the ECG blog has been down for almost a week. And now it&#8217;s back up again, but looks weird&#8230;..! The address, ecgblog.com will be kept, by the way.
Well, it&#8217;s all my fault. I&#8217;ve moved the blog from the Wordpress servers to a private host, and it&#8217;s been a bit [...]]]></description>

		<title>Happy birthday, ECGBlog!</title>
		<description><![CDATA[Happy birthday, folks!
It&#8217;s been a year since I created The ECG Blog, imagine that. I first started it because I needed a place where I could share my interest for ECG interpretation with others. I wanted to meet and discuss with people, to learn and be inspired. All of this and even more has come [...]]]></description>

		<title>Adams-Stokes / Complete (Third Degree) Atrioventricular Block</title>
		<description><![CDATA[Patient: 75 y/o male. Medical history and anamnesis unknown. Experienced several Adams-Stokes episodes and his wife called EMS. This is a prehospital 12 lead from the LP12.
ECG description:

No P-QRS relationship. Independent pacemakers.
Atrial rate is 125 bpm. Ventricular rate is close to zero.
No escape rhythm present
P axis is normal at 60 degrees

Discussion:
This is ventricular standstill. The [...]]]></description>

		<title>Sinus Rhythm evolving into PEA and Asystole</title>
		<description><![CDATA[Patient: n/a
ECG discussion: The top strip starts with sinus rhythm at ca. 75 bpm. Note that this generates a mean arterial pressure (MAP) of only 18 mmHg. A marked horizontal ST depression is also seen, which correlates with the pleth signal showing SpO2 of 74%. After 8 beats, there is no visible sinus activity any [...]]]></description>

		<title>Second Degree AV Block Mobitz 1; Wenckebach with 4:3 conduction + Ventricular and Junctional Escape Beats</title>
		<description><![CDATA[Patient/anamnesis: n/a
ECG interpretation/discussion: This ECG is a printout from a telemetry station, derived from a 5 lead patient monitoring.  So, what have we here? The underlying rhythm is sinoatrial, but both PR and RR interval varies. Remember, Wenckebach is not the name of a certain type of block, but rather a type of conduction. This [...]]]></description>

		<title>Pace Symposia&#039;s ECG simulator &#8211; as close to real as it gets</title>
		<description><![CDATA[Dear readers and fellow ECG enthusiasts.
The strict purpose of The ECG Blog is to discuss and educate ECG interpretation. I want to maintain a serious profile, so therefore every blog post has been a clear cut case presentation. Today however, I&#8217;ve decided to make an exception to be able to share some good news with [...]]]></description>

		<title>Atrial Bigeminy and Premature Ventricular Contraction</title>
		<description><![CDATA[Patient: n/a
ECG description:

Sinus tachycardia
Supraventricular bigemeny
One premature ventricular contraction

Discussion:
There is a baseline sinus tachycardia with a PR interval of 130ms, regularly interrupted by premature atrial contractions (PAC). Each PAC depolarizes the atria and resets the SA node, causing a change in automaticity and a noncompensatory extrasystolic pause. Judging by the PR interval as well as P [...]]]></description>

		<title>Sinus Arrest With Atrial Escape</title>
		<description><![CDATA[
Patient: Woman, 55 y/o, using metoprolol. Diabetes Mellitus II, angina pectoris, adipositas. Admitted with general weakness and fatigue, dehydration and dyspnea. Blood pressure is 100/55. No signs of infection.
ECG description:

Sinus rhythm with sinus arrest
Axis within the normal quadrant, at ca. 0 degrees
Poor R wave progression
Low amplitude in limb leads
Baseline artefact from patient movement
T wave flat/inverted [...]]]></description>

		<title>Dysrhythmia during hemodialysis</title>
		<description><![CDATA[Arrhythmias frequently occur in patients undergoing hemodialysis. Shinichi, et al. (American Heart Journal, Vol. 131, Issue 6, 1996:1137-1144) reports that out of 221 patients receiving hemodialysis, a total of 65% (143 pts) had ECG abnormalities, excluding sinus tachycardia and sinus bradycardia. The study looks at ECG abnormalities, not only arrhythmias, and left ventricular hypertrophy has [...]]]></description>
