1st degree block indicates slowed transmission of electrical activity through the AV node – therefore giving a prolonged PR interval. It can be a normal variant. 2nddegree heart block There are two varieties of 2nd degree heart block to be aware of: ...
1st degree AV block Not every atrial impulse is able to pass through the AV node to the ventricles, some P waves fail to conduct to ventricles so the ratio of P waves to QRS is over 1:1 2nd degree AV block Mobitz Type 1 (Wenckebach) 2nd degree AV blocks almost always occur ___ WI...
2nd degree AV block mobitz II There are intermittent blocks of sinus impulses in the AV node. Dropped beats occur without warning. Asystole The P wave may or may not be present. There is no conduction of the atrial impulse to the ventricles. QRS complexes are absent. Sinus Bradycardia The ...
