Teaching Series - Tachycardia and Left Anterior Fascicular Block

Sat, 10/15/2016 - 15:48 -- Dawn

This series of three ECGs is from a 60-year-old man who was brought to the Emergency Department after being involved in a motor vehicle accident.  No injuries were found, but the patient was severely intoxicated by alcohol consumption.  He was conscious but agitated. 

ECG NO. 1     15:07:23

Teaching Series: Acute Anterior Wall M.I.

Sun, 06/26/2016 - 15:33 -- Dawn

Intermittent chest pain.     This series of three ECG were taken from a 41-year-old man with a two-week history of intermittent chest pain.  At the time of the first ECG, 12:05 pm, he was pain-free.  We see a sinus tachycardia at 102 bpm, and has just come under the care of paramedics. There is a very subtle ST sagging and T wave inversion in Lead III, and no other ST changes. He had an uneventful trip to the hospital.

ECG Basics: Paroxysmal Supraventricular Tachycardia Treated With Adenosine

Sun, 12/28/2014 - 17:43 -- Dawn

This series of ECG rhythm strips shows a paroxysmal supraventricular tachycardia successfully treated with adenosine.  The patient was complaining of a rapid heart rate and palpitations, but was hemodynamically stable.  It is not known whether any parasympathetic stimulation, such as a Valsalva maneuver or carotid sinus massage, was used initially.   

Teaching Series: Atrial Fibrillation With Left Bundle Branch Block

Thu, 05/29/2014 - 23:28 -- Dawn

This is a good example of atrial fibrillation with left bundle branch block.  You get two ECGs with this one, because the patient presented to EMS with a fast heart rate, and the rate was slowed with the drug diltiazem.  We do not have any other patient information, unfortunately.

Teaching Tips: ECG Series WO 118: STEMI With Changing ST Elevations

Thu, 01/23/2014 - 23:15 -- Dawn

Continuing with our theme of using  series of ECGs for teaching, we present the case of an 83-year-old woman with weakness, chest pain, and near-syncope.  The first ECG, taken by paramedics at her home, shows a sinus rhythm with a slightly wide QRS complex.  At this point, it is unclear whether this represents left bundle branch block or a non-specific interventricular conduction delay. There is the most subtle ST elevation in Leads III and aVF. In LBBB without acute M.I., we would expect the ST segments to be discordant, or opposite, the QRS complexes.
