Welcome to the lesson on narrow QRS complex. pediatric techie arrhythmias are first divided into narrow, complex or wide complex techie cardia. In this video, we'll discuss the narrow QRS complex tacky Cardenas narrow QRS complex. Stacie hardy is include atrial flutter, sinus tachycardia, and super ventricular tachycardia, or svt. atrial flutter is an uncommon rhythm distinguished on an ECG as a sawtooth pattern. It is caused by an abnormal reinterred pathway that causes the atria to beat very quickly and effectively.

Atrial contractions may exceed 300 beats per minute, but not all of these will reach the AV node and cause a ventricular contraction. Most often as a PA LS provider, you'll have to distinguish between two similar narrow QRS complex techie arrhythmias, sinus tachycardia, and super ventricular tachycardia or svt. SVT is more commonly caused by accessory pathway re entry, AV node re entry, and a topic atrial focus project details and differences between sinus tachycardia and SVT please refer to table 17 in your correspond pls manual. This concludes our lesson on narrow QRS complex. Next, we'll review wide QRS complex.
