WebDefinition HR>100 with a QRS duration <0.12 sec (120 ms), can be regular or irregular. Given their narrow QRS duration they originate above the ventricle and are commonly referred to as a supraventricular tachycardia (SVT). An SVT may also have a wide QRS when there is aberrant conduction. WebIt is normal to have a narrow QS and rSr' patterns in V 1, and this is also the case for qRs and R patterns in V 5 and V 6. The transition zone is where the QRS complex changes from predominantly negative to predominantly positive (R/S ratio becoming >1), and this usually occurs at V 3 or V 4. dangerous dogs act section 1 https://revolutioncreek.com
