ECG Basics: Ventricular Tachycardia

Wed, 12/20/2017 - 15:00 -- Dawn

V tach is identified by:  wide QRS complexes (>.12 seconds), rate faster than 100 bpm.  In MONOMORPHIC V tach, all QRS complexes look alike.  There are other mechanisms of wide-complex tachycardia, but they can be difficult to differentiate from a single rhythm strip.  All WCT should be treated as V tach until proven otherwise.

Ventricular Tachycardia In A Patient With Myopathy

Tue, 12/19/2017 - 23:15 -- Dawn

These two ECGs are from a 77-year-old woman who was complaining of palpitations and mild shortness of breath.  She stated a history of atrial fibrillation.  She was alert, with a systolic BP over 120.  At the hospital, she was found to have cardiomyopathy, resulting in global hypokinesis. She also had significant coronary artery narrowing in her left main, left anterior descending, and circumflex, which were treated with coronary artery bypass graft surgery.
